A series of 520 nm green laser diodes from Arima Lasers, a Laser Components supplier, features eye-safe operation. The integrated automatic power control switches off the laser source as soon as a certain operating current level is exceeded. The chip contains the electronics as an application-specific integrated circuit and as a photodiode. The laser diodes are installed in a 3.3 mm housing, which protects them from electrostatic discharges up to 10 kV. Depending on the model, they guarantee a stable output power of 5 mW or 10 mW at supply voltages of 5.8 V to 7.0 V (DC). Their pulse width can be modulated up to 2 MHz.

Atik Cameras has released the first in its series of highly sensitive cameras for advanced scientific and industrial imaging. The model TE-77 uses the Teledyne e2v CCD77-00 sensor, which features 24 µm2 pixels over a 12.3 mm2 sensor area. Because the camera can be reliably cooled to −60 °C, it can achieve very low read noise and detect the faintest signals. Minimal saturation and exceptional detail are achieved as a result of the deep full-well depth of 300 000 e (summing-well depth of 600 000 e). Another key feature of CCD technologies is asymmetric binning to achieve even greater detail. Multiple options are available, including a 45 mm bistable, high-speed scientific shutter capable of 20.0 ms opening times. The TE-77 is suitable for demanding applications such as chemiluminescence, fluorescence, spectroscopy, microscopy, and bioluminescence imaging.

According to Toptica, its TopWave 229 CW laser is a suitable excitation source for deep-UV Raman and deep-UV fluorescence spectroscopy. Key features include its short wavelength, ultranarrow laser linewidth of less than 1 MHz, and output power of 10 mW at 229 nm. For fluorescence-free Raman, excitation below 250 nm is crucial for avoiding the overlap between the spectral regions of the Raman signal and the native fluorescence. In fluorescence spectroscopy, the 228.5 nm emission allows the detection of molecules with fluorescence spectra of less than or equal to 270 nm, which can only be excited with shorter-wavelength light. As a CW laser system, the TopWave 229 is free of the nonlinear and saturation problems common with pulsed-laser sources. To ensure high reliability and consistent, diffraction-limited beam quality (M2 < 1.3), the complete UV beam path is enclosed in a specially sealed compartment.

A new 375 nm UV-laser module in the Photon laser range from ProPhotonix is available in power levels up to 70 mW. The Photon laser is suitable for applications that require fast curing from a very focused UV light and for 3D printing applications, many of which currently use 405 nm lasers. The shorter wavelength allows the use of resins that are not as light sensitive, which reduces waste and the need to shield the resin from environmental light to prevent accidental curing. Available add-ons include various optical, CW, and modulation options; adjustable optics; and an enhanced boresight. They allow the compact, reliable Photon laser modules to be configured to address a range of applications. Those include particle analysis, since the shorter wavelength allows smaller particles to be detected and measured. ProPhotonix Ltd, 13 Red Roof Ln, Ste 200, Salem, NH 03079,

Andor Technology, an Oxford Instruments company, says its BC43 benchtop confocal microscope represents breakthrough instrumentation. Typically, microscopes that capture images in 3D are costly, complex to use, and located in specialized darkroom facilities. That is especially true for confocal technology, which delivers the highest-quality 3D images, particularly in thick and clinical specimens. The BC43 overcomes those challenges by delivering 2D confocal images in milliseconds and generating 3D views in real time. The compact design means it can sit on a bench in a regular laboratory, saving space and time. The cost-effective BC43 is simple to use but can address complex imaging needs for live and fixed specimens. It handles a range of scales, from the subcellular and single-cell levels through those of huge tissue samples and large model organisms.

Thanks to its back-illuminated image sensor, the pco.edge 10 bi CLHS scientific CMOS camera from PCO, an Excelitas company, delivers a quantum efficiency of up to 85% and a broad spectrum out to the near-IR. The sensor incorporates microlenses and a full-pixel-height deep-trench isolation for cross-talk suppression, which results in a high modulation-transfer function. By using a high-resolution 10.5-megapixel image sensor with a square pixel size of 4.6 µm, the camera provides a large image circle. Thermal stabilization and active sensor cooling produce a very low dark current and readout noise of 0.8 e. The sensor technology reduces the noise peak and tail to a level comparable to the noise behavior of CCD sensors. Together with a high full-well capacity, that yields a dynamic range of 25 000:1. The pco.edge 10 bi camera offers high frame rates, of up to 120 fps, and transmission via a fiber-optic link. It is suitable for applications in microscopy and the life and physical sciences.

PI (Physik Instrumente) has redesigned its portfolio of compact vertical positioners for microscope objectives, known as PIFOCs. They are suitable for integration in objective revolvers of upright and inverse microscopes. The new P-725 piezo-based lens scanners offer higher dynamics due to optimized levers and steel mounts and are available in three travel ranges: 100 µm, 400 µm, and 800 µm. Handling of the PIFOCs has been optimized: The aperture has the largest possible diameter, and a set of adapter rings can be used to screw in different objectives up to M34 in size. A new cable sheathing makes possible much tighter-bending radii, which help protect the signal- and current-carrying cable from the mechanical strain induced by repeated rotations of the nosepiece to change magnification. The PIFOCs can be used in the life sciences, materials microscopy, quality assurance, and the semiconductor industry. PI (Physik Instrumente) LP, 16 Albert St, Auburn, MA 01501,

Nanosurf has announced a new atomic-force-microscopy (AFM) imaging mode available exclusively on the company’s DriveAFM platform. According to Nanosurf, WaveMode is the fastest force-curve-based imaging mode that can be applied to all samples and all environments. It is based on CleanDrive, Nanosurf’s exclusive photothermal cantilever actuation, which provides stable, low-drift, and high-signal-to-noise cantilever tunes that are insensitive to changes in the environment. WaveMode represents the first commercially available off-resonance mode that can use photothermal actuation of the cantilever—instead of traditional piezoacoustic actuation—to enable fast, stable, and gentle imaging. WaveMode offers fully automated laser and photodetector alignment. Usable in both liquid and air environments, it is suitable for AFM imaging in life and materials sciences applications.

Raptor has added the Eagle 1MP to its range of cooled CCD cameras. With a back-illuminated CCD sensor from Teledyne e2v (CCD47-10) providing 1056 × 1027 pixels with 13 µm × 13 µm pixel pitch, the Eagle 1MP enables large-field-of-view imaging and ultrasharp image resolution. It is housed in Raptor’s proprietary PentaVac vacuum enclosure and cooled to −90 °C with air and liquid and −80 °C with only air to minimize dark current for longer exposures. Using low-noise electronics, the Eagle 1MP offers less than 2.3 e readout noise unbinned and programmable binning options up to 16 × 16 pixels and dual readout rates of 75 kHz and 2 MHz. It comes with a C mount and an integrated shutter, which is closed during readout to avoid vertical smear. According to the company, at 140 mm × 126 mm × 120 mm, the Eagle 1MP is the smallest camera in its class.
