high quality plano-convex lens ,VR optical lens , optical glass lens with coating film

UV grade JGS1 FUSED QUARTZ GLASS OPTICAL LENS CUSTOMIZED 

Ultraviolet-melt quartz has a high transmittance from ultraviolet to near infrared (185-2100nm), with high transmittance in the deep uv region.In addition, compared with h-k9l (n-bk7), it has better uniformity and lower thermal expansion coefficient, especially suitable for high power laser in ultraviolet to near infrared band.When the light is converging, if the absolute magnification is less than 0.2 or greater than 5, the convex lens is usually selected.When the magnification is between 0.2 and 5, a double convex lens is more suitable.In order to reduce the difference of the ball, the parallel light in the focus should be on the surface of the flat convex lens.Various coatings can be selected. Please refer to the technical data for detailed parameters.The price is the tax price of coating, please consult customer service for the price of the substrate.
