Optical Filter by Reynard Corporation

Note: Your Quotation Request will be directed to Reynard Corporation.

The R0140x-00 from Reynard Corporation is a density gradient filter that allows transmission at a wavelength range from 375 nm to IR. It has a calibrated wavelength of 632.8 nm and an optical density of 0.04 - 5. This optical filter is manufactured using BK7 or equivalent substrate material and has a scratch & dig surface quality of 80 - 50. It has a clear aperture of 90 % and bevel of 45 degrees. This optical filter has an outer diameter of 25 mm ± 0.2 mm and a clear center. It has a beam deviation of up to 3 arc minutes and transmitted wavefront error of up to 2 waves per 25 mm. 

The R0140x-00 has an absorption of 10 % - 35 % depending on the coating materials and an inverse apodizing configuration. It can eliminate undesirable intensity variations in optical systems or to modify the wavefront of an illumination source. This optical filter has continuous wave laser damage of up to 30 W/cm2 and the size can be varied from 25 mm to 50 mm (customizable). It is ideal for astronomy, entertainment, imaging, industrial, military, photography, scientific, and semiconductor applications.
