1535nm Narrow Bandpass Filter
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.
