The OPTOStokes LP910 is a high-precision 910nm longpass filter engineered for advanced Near-Infrared (NIR) systems. This longpass filter features a sharp transition edge, providing superior suppression of visible light and shorter NIR wavelengths (350-880nm) while maintaining exceptional throughput (T > 90%) for signals above 910nm. It is a critical component for achieving a high high SNR in demanding optical environments.
