Thorlabs' selection of dielectric-coated spectral filters are presented here. Soft-coated bandpass filters are available in the visible, near-IR, and infrared ranges. Our bandpass filters feature a dielectric-stack Fabry-Pérot interferometer design. Our hard-coated bandpass filters offer higher transmission and are more durable and longer-lasting than our soft-coated bandpass filters. We offer an IR blocking filter that rejects light in the NIR range.
