A new motorized polarizer module from Telops allows hyperspectral measurement at user-defined angles of infrared scenes in a linear polarization state. The Hyper-Cam is claimed to provide good resolution of optically active targets such as man-made objects, surface contaminants, liquid films, and minerals. The module integrates an IR polarizer mounted on a 360° rotation stage that has a continuously tunable angle capability. Specifically designed for operation in the medium- or long-wave spectral bands, the wire-grid polarizer filters out off-axis polarization components of the incident light from the scene. The module can be quickly installed between the sensor head and the calibration module, allowing for calibrated data even in polarized mode.—Telops, 100-2600 St-Jean-Baptiste Avenue, Québec City G2E 6J5, Québec, Canada.

The Cazadero Scientific fiber-based femtosecond laser has been designed to offer a reliable, economical alternative to solid state laser amplifiers in biomedical, scientific, industrial, and research. Green (515 nm) and UV (343 nm) laser output options are now available in addition to the primary 1030-nm wavelength. The output of the three wavelengths can be collinear or from separated ports. The fiber laser-based chirped pulse amplification system generates high-energy, ultra-short (<0.5 ps) pulses at a repetition rate up to 1000 kHz for either 1 or 1.5 μm wavelengths. The pulse repetition rate and pulse energy are user-selectable and the pulse width tunable up to 30 ps. The user can optimize the pulse shape and its minimum width for any given repetition rate. The system starts with a passively mode-locked seed fiber laser. The short pulse is time-stretched by frequency (chirped) for lower-intensity amplification through a high-power fiber amplifier stage. Up to 30 μJ of short pulse energy is delivered into free space, with a typical minimum pulse width of 370 fs. The company's “arbitrary pulse picker” feature permits the user to select individual pulses to be emitted. Customizable “burst” mode pulse sequences and air-cool features are offered, and a RF output signal allows easy synchronization to the laser. A data log functions as a tool for system diagnostics and quality assurance, measuring and recording all relevant performance data over the life of the laser. Applications for the lightweight, compact, flexible system may be found in nanoscience, materials precision machining, biomedical instrumentation, terahertz radiation, and nonlinear optical studies.—Calmar Laser, Inc., 575 North Pastoria Avenue, Sunnyvale, California 94085.

According to McPherson, its STS spectral test and calibration station critically analyzes and tests the spectral and spatial performance of sensors reliably and conveniently. Broadband, multispectral, and hyperspectral sensors and imagers are widely deployed and commercial, military, and research sectors have special IR or UV response requirements. Users of the STS can test and characterize optical seekers, spectral signatures, integrated imagers, and bare sensors. They can conduct absolute measurements of transmission, reflection, stray light sensitivity, and head-on or incidence-angle-dependent response. The instrument uses a single optical path, simply providing continuity for measurements from the UV through the visible and into the mid- and long-wave IR. Reflective optics enables efficient operation throughout the wide spectral measuring range. Features include variable bandwidth, easy-to-change diffraction grating, light source, and detector turrets. Linearity and signal-to-noise ratio measurements are simplified since the STS can easily change bandwidth. The instrument can be customized to meet specific needs, for example, systems providing high spectral purity or those having large format receivers and senders with up to 300-mm clear apertures or more.—McPherson, Inc., 7-A Stuart Road, Chelmsford, Massachusetts 01824-4107.

Bruker has introduced the Opterra multipoint scanning confocal microscope for integration of confocal imaging with photoactivation. Novel features are used to obtain the speed of wide-field imaging and the resolution of traditional confocal systems while minimizing phototoxicity, making the Opterra suitable for gentle, fast confocal imaging of live cell preparations. A seven-position pinhole/slit aperture allows it to be optimized for varying objective lens magnifications. Therefore it can image deeper into tissue than conventional disk scanning confocal microscopes. Based on Bruker's patented swept-field imaging scanner, which allows high-speed confocal imaging of live cell and small organism preparations at resolutions comparable to conventional point scanners, the Opterra includes a second scanner for photoactivation/bleaching/ablation. It can operate simultaneously with imaging. The photoactivation scanner can be coupled to both visible and multiphoton lasers, thus allowing the use of the full range of photoactivatable molecules and photochemical techniques available to life sciences researchers. In the case of multiphoton lasers, this provides precise three-dimensional control over photoactivation. The applications addressed by Opterra include kinetics of photoactivatable fluorescent proteins; fluorescence recovery after photo-bleaching; and response to local stimulation of channel proteins and to DNA and cell membrane damage. Bruker's Prairie View 5.0 software provides an intuitive interface environment for defining image acquisition and photoactivation protocols.—Bruker Nano Surfaces Division, 3400 East Britannia Drive, Suite 150, Tucson, Arizona 85706.

Asylum Research, an Oxford Instruments company, has announced an atomic force microscopy (AFM) technique that enables nanoscale mapping of permittivity and conductivity with high sensitivity and resolution on any material, including conductors, semiconductors, and insulators. Scanning microwave impedance microscopy (sMIM) is the latest tool in Asylum's “beyond topography” initiative that seeks to provide useful nanomechanical

and nanoelectrical information in addition to high-resolution AFM topography. Incorporating electronics and proprietary AFM probe technology developed by PrimeNano, sMIM is available integrated exclusively with Asylum Research MFP-3D and Cypher AFMs. Nanoelectrical AFM modes have long been used in microelectronics R&D applications because they can provide valuable insight into device structure, function, and failure. However, most conventional modes have been limited to measuring either resistance or capacitance and have required laborious sample preparation. According to the company, sMIM improves on these technologies because it senses sample variations in both conductivity (resistance) and permittivity (capacitance) while requiring only minimal sample preparation. These capabilities also make sMIM applicable to a broader range of samples, including ferroelectrics, piezoelectrics, and low-dimensional nanomaterials like graphene, boron nitride, and molybdenum disulphide.—Asylum Research, 6310 Hollister Avenue, Santa Barbara, California 93117.

Harvard Apparatus-Hugo Sachs Electronik has released a pressure monitor and limiter for use with any small animal volume-controlled ventilator. The new peripheral is designed to protect the lungs of rodents, including mice, from typical barotrauma caused by mechanical ventilation. An analog output of the ventilation pressure signal allows researchers monitoring system pressure to make corrections, optimizing animal ventilation. They can also set a system pressure limit; if a condition causes the pressure to exceed the limit, a valve opens and the excess pressure is exhausted. Of a size appropriate for mice, rats, and guinea-pigs, the unit features a peak inspiratory pressure range of 10–50 cm H2O, continuous ventilation pressure measurement, transistor–transistor logic output of valve status, audible alarm, and compatibility with any small-animal mechanical ventilator, for example, the company's model 683 or Minivent.—Harvard Apparatus, 84 October Hill Road, Holliston, Massachusetts 01746.

Version 3.0 data acquisition software is now available for PicoQuant's PicoHarp 300 time-correlated single photon counting (TCSPC) system. The new software provides a programmable time offset in the sync input to replace adjustable cable delays (4 ps resolution, ±100 ns) and a programmable time offset in all PHR 800 router channels to tune for relative delay (4 ps resolution, ±8 ns). Improvements in usage and user interface include a future-proof file format and export of histograms

directly to ASCII files. The PicoHarp 300 is based on a new time digitizer with 4 ps resolution, a very short dead time, a processing rate of up to 107 counts/s, and an extremely low differential non-linearity. Compared to classical TCSPC systems it provides novel features, notably two identical input channels that can operate independently, but with a common crystal time base. Therefore, users can obtain not only traditional TCSPC histograms for the measurement of fluorescence decays, but also picosecond coincidence correlations. This is implemented using the instrument's time-tagged time-resolved (TTTR) mode, which records the picosecond arrival time of each individual photon. External marker signals can be recorded for synchronization with other processes, allowing fluorescence lifetime imaging with most existing imaging devices including laser scanning microscopes. Dedicated upgrade kits are available for popular microscope models. Fluorescence lifetime images can be recorded at virtually any resolution and size. The new version provides a programmable marker holdoff time to suppress glitches on the control signals. Software-controlled constant fraction discriminators in all input channels ensure precise, optimized timing for a wide range of detectors. Optional accessories for signal conditioning such as pre-amplifiers, attenuators, and signal inverters allow adaptation to many laboratory signal sources. Sync/excitation sources can be as fast as 85 MHz, but even very slow sources can be used efficiently with “multi-stop” acquisition on the detector channel. The software provides warnings in situations where measurement conditions are suboptimal or user settings are potentially erroneous. The PicoHarp 300 is designed as a USB 2.0 “Plug and Play” device, allowing control and data acquisition from a desktop or notebook personal computer. The USB interface is designed to guarantee a sustained TTTR mode throughput of 5 × 106 counts/s for virtually any measurement time required. The new software is provided free of charge to owners of a PicoHarp 300.—PicoQuant GmbH, Rudower Chaussee 29, 12489 Berlin, Germany. (49-(0)30-6392-6942)http://www.picoquant.com

Golden Software has released Surfer 12, a new version of its gridding and contour mapping software package used by geologists, hydrologists, and engineers to transform data into clear, accurate, presentation-ready maps. It offers 12 different gridding methods, including Kriging with variograms, to convert irregularly spaced XYZ data into a uniform grid. A grid or digital elevation model may be displayed in one of eight fully customizable 2D and 3D grid-based map types: contour, watershed, image, shaded relief, 1-grid and 2-grid vector, 3D wireframe, and 3D surface maps. Post and base maps can be added to enhance the display. New features in Surfer 12 include the ability to grid and display data using a logarithmic scale. The log of the Z data can be taken prior to gridding and the grid saved with either log or antilog values. Contour maps with logarithmically scaled contour intervals can be created, and maps filled with a logarithmically scaled color gradient. This is useful for creating accurate maps when the data set spans several orders of magnitude. Users can now also reverse the X or Y axis direction and use date/time data to create maps. Descending data, such as depth data, can be shown in the correct orientation without modifying the raw data, and data visualized with respect to time. Other upgrades to Surfer 12 are downloading free online maps directly from Web Map Service (WMS) servers, saving server response files in the format of the previous version of Surfer, and adding multiple labels to points in a post map. Surfer connects directly to online WMS servers, allows the user to pick the layers desired for download, and integrates the images into existing projects. A Surfer 12 user can share their project with others who have not yet upgraded by saving it in Surfer 11 format. Among enhancements to post maps is the ability to create multiple labels for each point. Users can display all the important information at each point location with a click of a button.—Golden Software, Inc., 809 14th Street, Golden, Colorado 80401-1866.
