HHV’s black absorber coatings are developed using an optimal design of multiple metal-dielectric layers on stainless steel substrates. These coatings are hard and adherent and have an average reflectance of less than 1% in the visible range. They are widely used in space applications. These high absorbance coatings provide superior stray light suppression and attenuation, thereby significantly improving signal to noise ratio. Coatings are space worthy. PRODUCT FEATURES - Substrate: SS-304, Glass - Dimension: Diameter up to 200 mm - Durability: MIL-C-675A, MIL-M-13508C - Custom coating designs developed and produced on request. APPLICATIONS - Used for light trapping applications in lens housings, light baffles, IR sensors and light detectors .
