Product Description

Dichroic Shortpass Filters

Dichroic Shortpass Filters are designed for a 45° or 0° angle of incidence. The rejected light is reflected at 90° or 0°, making these filters ideal for use in fluorescence applications or as spectral beamsplitters. The filters feature low polarization dependence, broad spectral ranges, and a precision fused silica substrate.

Short pass filters can effectively cut off the near-infrared band of light. They are widely used in various cold light sources, optical fiber lighting, LED lighting, metal halide lamp insulation, and infrared cut-off filters for optical imaging schemes: optical engines, filters for digital cameras to eliminate near-infrared interference from CCD and CMOS, to ensure the normal operation of photoelectric instruments and equipment.
