Where to Buy Interference Filters

Artifex Engineering offers custom interference filters for use in the UV, VIS and IR. Bandpass filters, notch filters, highpass or lowpass filters are available and can be cut to any shape. To reduce the number of layers, absorption filters (color filters) can be combined with a dielectric coating. Black anodized aluminium rings may be provided for ease of mounting. Visit our product page for more information. We look forward to your inquiry.
