optical glass material

Products description It's fabricated by special color glass material(band pass filter, long or short pass filter, neuftral density filter). The material will absorption some wavelengh and appeare different colors. Guoguang Optics can manufactrue variety types of optical glass material which are similar with Schott products. It can provide any size, shape and quality required by customer. Products classfication Guoguang filters material can be classified into three groups according to transmission curve. • Band pass filter material: Selectively transmit a desired wavelength range • Short, long pass filter material: Block the short or long undesired wavelengh range • Neutral density filter material: Similar absorption for the whole visible wavelength range Guoguang filters material can be classified into according to products series. • HB, HWB (Schott RG): Red and black glasses, IR transmitting • ZWB(Schott UG): Black and blue UV transmitting • QB (Schott BG): Blue, blue-green and multi-band glasses • LB (Schott VG): Green • JB, CB(Schott GG): Nearly coloress to yellow, IR transmitting • CB(Schott OG): Orange • ZAB (Schott NG): Neutral density glasses with uniform attenuation in the visible range • GRB (Schott KG): Heat absorption filters Advantages • All the filter glass material can be used as substrates for thin film coating to manufacture so-called interference filters. • Material used in colored glass filters include basic glass types, ionically colored glass as well as colloidally colored glass. Fabrication Capabilty Shape: customization Dimension: customization Surface quality: 60-4- commonly, up to 40-20 Flatness: Lambda/2 commonly Parallelism: <30" Ar coating is available upon request.
