BK7/B270 optical glasses 

   Color optical glass of Ruisen Optics has hundreds of different curve. Supply optical filter from 200nm to 2500nm. Optical glass has color optical glass and colorless optical glass. Color optical glass has phosphate glass and silicate glass. Apply Se and Cd color and selective absorption glass of ion color neutral(Dark) glass. They are widely used in university and institute, research development and military, policy, medical instrument and finance etc.

    cut-off type: block the short wavelength by ab sorption and transmit the long wavelengthselective absorption type:transmission (or absorption) one wavelength (or several wavelengths)neutral density type:similar absorption for the whole visible wavelength range

    The optical glass is the glass material used in the lens, prism, reflector and windows of optical instruments and optical equipments. The various kinds of optical glass are as the follows: Uncolored optical glass, colored optical glass, laser glass, radiation resistance laser glass, radiation protection laser glass and quartz glass. The uncolored optical glass is commonly regarded as the optical glass, which is one of the general specifications in glasses. There are over 200 kinds of number features in total. Each feature has its own optical constants, uniformity, transparency and chemical durability.
