Precision Optical Components
Optical Filters, Mirrors, Coatings & Light-Control Components
Organized by optical function — find the right product family for your wavelength, thermal, reflection, or beam-management challenge.
Filter Families
Transmission, rejection & spectral shaping
Isolate useful wavelengths, suppress unwanted bands, manage heat, and improve spectral repeatability.
Mirror Families
Beam paths & thermal management
Broadband reflection, wavelength-selective routing, color-channel splitting, and heat separation.
Coatings & Beam Management
Reflection control, stray light, and beam routing
Increase useful transmission, limit parasitic reflection, split beams, and control off-axis light.
Specialty Components
Aperture control & solar simulation
Precision accessories for optical tuning, calibration, and application-specific setups.
Selection Support
Not sure which product family?
Start with the optical problem: isolate a band → bandpass, notch, shortpass, or longpass. Managing heat → hot mirrors, cold mirrors, IR filters. Reflection or stray light → AR coatings and black coatings.
If you know the light source, detector, wavelength region, or target behavior, KUPO can help map that to the right family or discuss a custom direction.

Custom Programs
Beyond standard collections?
Many programs need more than a stock part. KUPO supports application-driven selection where wavelength region, blocking level, thermal behavior, substrate, and system constraints matter together.
