Optical Interference Filters and Holographic Diffraction Gratings

A world-leading manufacturer with decades of expertise supplying superior optical filters and holographic diffraction gratings for high-demand applications.

Optical Interference Filters

SPECTROGON designs and manufactures thin film filters supporting various high-demand applications including gas analysis, thermal imaging, defense/surveillance, gas/flame detection, process control, power distribution, medical, automotive, semiconductor, environmental monitoring, distance measurement, scanning system, food/beverage and space. Our optical filters and windows cover the range of 380-15000 nm, in sizes from Ø 5 to Ø 200 mm. Wafers can be diced to the required size in our high-performing dicing facility and delivered on tape frames. We produce bandpass, long/shortwave-pass, and broad-bandpass filters to customers specifications. Our filters, manufactured using a hard coating technique, offer superior environmental stability. Thin film designers are ready to review your requirements and propose solutions. All production is in Sweden, with a selection of coating machines suitable for different wavelength ranges and volumes. For low volume prototypes, an extensive range of filters from stock can be offered. 

Holographic Diffraction Gratings

SPECTROGON manufactures holographic diffraction gratings for UV-NIR. Our custom-made gratings have high efficiency, low stray light, a 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 can help you to determine a specification that is both technically feasible and economical to manufacture. All grating requests submitted to us are calculated and simulated for optimal performance and matched against stock or previously manufactured gratings.
