Spectrogon is a world leading manufacturer of Optical Interference Filters and Holographic Diffraction Gratings.
Product range includes filters for wavelength region 200-15000 nm. Most common manufacturing sizes are: Ø6.0, Ø10.0, Ø12.7, Ø25.4, Ø50.8, Ø75.0, Ø100.0 and Ø200.0 mm. These filters can easily be cut to the required size in our cutting facility. All filters are manufactured with a hard coating technique, which give films with superior environmental stability. We have over 300 000 filters in stock for immediate delivery. These are produced on various wafer sizes, ready to be cut according to your requirement. On our website we present a selection of over 1000 different filter types with specifications and spectral curves. For prototype or production, we have several thin film designers ready to review your specifications.
Spectrogon manufactures holographic diffraction gratings for UV-NIR. Our custom made gratings have high efficiency, low stray light, wide tuning range, high damage threshold and optimized for specific applications. For custom designs we have several grating designers ready to review your specification. We help you to determine a specification that is both technically feasible and economical to manufacture. For prototype work and for predefined gratings we list approximately 250 gratings with optical characteristics and other specification in our website www.spectrogon.com. All grating requests submitted to us are calculated and simulated for optimal performance and matched against stock or manufactured gratings.
