Dichroic Filters
Dichroic Filters
Dichroic filters represent Andover's advanced solution for precise color separation and light management.
Using hard dielectric film technology instead of organic dyes or gelatin, these filters provide exceptional spectral isolation while maintaining long-term stability.
Their unique ability to both transmit and reflect specific wavelengths makes them ideal for applications requiring precise light beam separation or combination.
The filters can be optimized for different angles of incidence, with many applications utilizing their reflective properties at 45° for color combining.
