872A-VIS and 872A-NIR Laser Wavelength Meters
Bristol Instruments has announced a new Laser Wavelength Meter ideal for the frequency stabilisation of lasers. The new models 872A-VIS and 872A-NIR combine high measurement resolution with reliable accuracy. Supporting laser wavelength
measurements from 375 to 1,700nm, the new models offer a frequency resolution better than 300kHz at 300,000GHz, which results in exceptional sensitivity to wavelength deviations. With a built-in PID controller and 1kHz sustained measurement rate, the 872A system is well suited to precisely stabilise lasers used for applications such as atomic cooling and trapping. According to Bristol Instruments,
the new Laser Wavelength Meters provide the highest resolution wavelength measurement of virtually any laser, and are set to benefit scientists and engineers who need to maintain the exact wavelength of their lasers.

Advanced LTO Infrared Detectors
Laser Components has introduced the ultrathin LTO detector (Lithium Tantalate: LiTaO3), which minimises noise while at the same time exhibits high responsivity via sub-pixel binning. The Advanced LTO Infrared
Detectors operate well within room temperature with no depoling concerns and require no
OmniCure LS200 UV LED Radiometry and Calibration System Excelitas Technologies has launched the OmniCure LS200 UV LED Radiometry and Calibration System for precise and accurate measurement and calibration in UV LED spot curing. The system has applications in electronics assembly, medical device manufacturing, automotive, defence/aerospace and more. The LS200’s sensor calibration is NRC traceable to
provide additional assurance of accuracy. The company says the system’s OmniCure Beam Positioning Kit and LX500 controller deliver exceptional control and repeatability of output measurement, boosting productivity and final-product quality. Users can choose between two LS200 models to perform either irradiance measurements or optical
power measurements based on application needs. The system measures optical power across a 1mW to 2,000mW range, or a 50mW/ cm² to 40W/cm² irradiance range, to enhance support of applications with higher power requirements. To simplify the setup process and ensure users have
all the required tools for accurate measurement and calibration in one package, Excelitas offers complete OmniCure LS200 calibration kits. The kits include all of the necessary components such as Excelitas’ light sensors, a LM2011 Light Meter Display, and a Beam Positioning Kit for precise alignment of LED heads for accurate measurement.

QE195LP-S-MB and HP100A-50KW-GD beam detectors Gentec-EO has recently launched two measurement solutions for extra wide and extra high-power laser beams. The QE195LP-S-MB features an effective aperture of 195mm. This pyroelectric laser energy detector can measure every pulse at up to 200Hz and up to 700J. With a noise level as low as 0.1mJ, this detector can be useful in a wide range of experiments. Gentec-EO also recently added a 145mm aperture model that can measure up to 385J. The instruments were designed to meet the needs of laser scientists and engineers in industries such as high-energy laser science, advanced materials research and processing, energy production, and fusion research.
The HP100A-50KW-GD laser power detector was designed mainly for high-power laser and laser system
manufacturers, factories that cut thick metal parts with high-power lasers, and military applications. With its gold reflector cone and back-reflection reducing geometry, the HP100A-50KW-GD traps > 97% of the incident light and can handle up to 50kW of continuous laser power. The very low back-reflections of the detector ensure a safer working environment with high-power lasers. This detector can also handle the high intensities of smaller beams.

temperature stabilisation, which is typical for DLaTGS detectors. These pyroelectric detectors operate within single channel voltage mode without the need for cooling. The company states the detectors can maintain high performance up to 1kHz and can be used out to approximately 10kHz with fast response to IR flux changes. The flexibility for users to choose a wavelength range that best fits
an application is enabled with the selection of transmission windows. The prominent choice that is identified being a KBr window that transmits out to 30µm with an option for a parylene moisture protective coating. Additional BaF2, CaF2, CsI, CVD diamond, silicon, and ZnSe transmission windows are also available from Laser Components.
