The PIN detector is a high-performance photodetector made of InGaAs material, designed specifically for wide wavelength response and high sensitivity applications. It can effectively detect wavelengths in the range of 990nm to 1650nm, featuring excellent responsivity and low dark current characteristics. This makes it highly suitable for optical measurement equipment and laser radar systems.
The 1535nm narrow bandpass filter is a high-performance optical filter specifically designed to allow light at the central wavelength of 1535nm to pass through while effectively blocking light at other wavelengths. This filter features a narrow bandwidth, high transmission rate, and a wide operating temperature range, making it ideal for applications in LiDAR and laser ranging.
