Bristol Instruments has added the model 671A-MIR to its 671 series of laser wavelength meters. The 671A-MIR supports the characterization of free-space, mid-IR lasers operating in a broad spectral range. The most precise instrument in the 671 product family, it provides an accuracy of ±0.2 ppm in the 1.5–5 µm spectral range and an accuracy of ±1 ppm in the 5–12 µm spectral range. To achieve reliable accuracy for demanding applications, the 671 laser wavelength meters are continuously calibrated with a built-in helium–neon (HeNe) laser. This is an ideal reference source because its wavelength is well known and fixed by fundamental atomic structure. To achieve the highest accuracy, the model 671A uses a single-frequency HeNe laser that is stabilized using a balanced longitudinal mode technique. For less exacting experiments, the company offers the more economical model 671B with an accuracy of ±0.75 ppm. It uses a standard HeNe laser as the wavelength reference.

Cryomech has unveiled its PT450 pulse-tube cryocooler and CP3000-series helium compressor. According to the company, the combination delivers a heat removal rate, or heat lift, of 5.0 W at 4.2 K, which will facilitate advances in ultralow-temperature applications, including the superconducting qubit modality in quantum technology. The demand for higher-powered dilution refrigerators to cool superconducting qubits has increased, and with it the need to balance the high heat lift and the ultralow vibration required to achieve fast cooldown. Cryomech says its pulse-tube cryocoolers meet those demands. The PT450 features a base temperature of less than 2.8 K, a cooldown time of 60 min to 4 K, and a long maintenance interval. And it’s compact compared with many available 4 K cryocoolers. Cryomech Inc, 6682 Moore Rd, Syracuse, NY 13211,

Rohde & Schwarz now offers new software for its BBA300 RF amplifiers. The BBA300-PK1 software option lets users accurately set the operating parameters of the amplifier and manage test sequences. It introduces two tools with which users can fine-tune test signals and react flexibly to various requirements. The first is the ability to shift the operating point between Class A and Class AB, which changes the amplifier’s response. As a Class A amplifier, the BBA300 provides excellent linearity and harmonic performance. Shifting to Class AB allows pulsed signals to be reproduced accurately and more efficiently at high power. The BBA300-PK1 software also lets users set the amplifier between high power mode for maximum power with a well-matched RF path and VSWR (voltage standing wave ratio) mode for rated power with high tolerance to load mismatches. The VSWR mode is useful in electromagnetic compatibility applications because it maintains rated power up to a VSWR of 6:1. Rohde & Schwarz GmbH & Co KG, Mühldorfstrasse 15, 81671 Munich, Germany,

PicoQuant has announced its Snappy application programming interface (snAPI). It is a Python wrapper that enables seamless communication and configuration with the company’s time-correlated single-photon counting (TCSPC) and time-tagging electronics. By leveraging the power of Python, users can build their own algorithms, implement complex calculations, and develop tailored data-processing pipelines for analysis. Taking advantage of C++ for optimal speed and performance, snAPI bridges the gap between the high-speed capabilities of PicoQuant’s TCSPC devices and the ease of use and flexibility of Python. The low-level control offered by C++ ensures smooth data processing and enables efficient handling of large photon counts and their real-time analysis. The wrapper provides the option to access unfolded data from the TCSPC devices or conveniently read from PTU (Performer Terrain Utilities) files. That allows researchers, developers, and scientists to explore their data more deeply and extract valuable insights. PicoQuant’s snAPI is available free at GitHub.

The IRis-C is the next-generation instrument in IRsweep’s quantum cascade laser (QCL) frequency-comb spectrometer line. It uses the same dual-comb spectroscopy technology as IRsweep’s IRis-F1, which offers microsecond time resolution, high spectral resolution, and high optical brightness in the mid-IR, but has been reduced in size and cost. Within a compact design, the prealigned reference-beam path ensures high signal quality, and the free-space sample beam ensures easy coupling to any application-specific interface. The high optical power of QCLs facilitates their use with strongly absorbing samples, such as aqueous solutions, and the internal coalignment of the two frequency combs ascertains good copropagation over distances of up to 2 m. The IRis-C is suitable for chemical and biochemical reaction kinetics, protein folding and similarity tests, catalysis studies, combustion diagnostics, and other challenging vibrational spectroscopy tasks.
