High Reflective Optical Mirror With Aluminium Coating Gold Coating And Dielectric Coating

Hanzhoung Heng Pu K9 optical glass, K9 (H-K9L, N-BK7) is the most common optical materials, from the visible near infrared (350-2000nm) has excellent transmittance, in the telescope, laser and other fields are widely used. H-K9L (N-BK7) is the most commonly used in the preparation of optical glass with high quality of optical elements, when additional advantages do not need UV melted quartz (transmittance and low coefficient of thermal expansion is very good in the UV band), will generally choose H-K9L. Hanzhoung Heng Pu UV melting stone, UV melting zircon (JGS1, F_SILICA) from the ultraviolet to the near infrared band (185-2100nm) has a high transmittance in the deep ultraviolet region has high transmittance, which is widely used in UV laser. In addition, compared with H-K9L (N-BK7), UV grade fused zircon has better uniformity and lower thermal expansion coefficient, which can be applied in the ultraviolet to the near infrared band, high power laser and imaging field.
