Products Description

LP920 920nm Longpass Filter | Ultra-Thin 0.55mm for Compact NIR Systems(pic1)

The OPTOStokes LP920 is a high-performance 920nm longpass filter specifically engineered for applications where space and weight are critical constraints. This ultra-thin filter provides a sharp spectral transition, effectively blocking shorter wavelengths up to 900nm while maintaining over 90% transmission in the Near-Infrared (NIR) spectrum. Its precision thin-film construction makes it an ideal IR window for advanced sensing modules.
