Products Description

LP1500 Longpass Filter | 1475-1800nm Transmission
The OPTOStokes LP1500 is a high-performance short-wave infrared (SWIR) longpass filter designed for precise spectral separation. Engineered with hard optical coatings on durable substrates, this filter provides a sharp cut-on slope to isolate critical SWIR wavelengths while effectively blocking shorter visible and near-infrared light. It serves as an ideal component for maximizing signal-to-noise ratios in high-precision optical systems.
