With high sensitivity, high speed, and high data rate transmission, Hamamatsu’s InGaAs linear image sensor modules perform reliably in the near-IR for easy image acquisition, transfer, and synchronization. Featuring our top-performing InGaAs image sensor, the module offers sensitivity in the NIR region of 0.95 to 1.7 μm, and reaches a high-speed line rate of 40 klines/s.

Bristol Instruments’ popular 871 system measures laser wavelength at a sustained rate of 1 kHz, the fastest available. It also measures wavelength to an accuracy as high as ±0.0001 nm. By combining proven Fizeau etalon technology with automatic calibration, the most reliable accuracy is ensured for the most meaningful experimental results.

Linear apodizing filters are used to eliminate undesirable intensity variations in optical systems. When inserted in front of a detector, a filter can be used as a soft slit to reduce diffraction patterns, eliminate detector saturation, and obtain a uniform light intensity to the detector. The filters have a constant density in one direction and variable neutral density filtering in the other direction.
