Quartz Parts
    1. CNC Quartz Parts / Glass Parts
    2. CNC Quartz Parts / Glass Parts With the help of CNC design and software control, we are able to fabricate the precision glass parts and precision quartz parts especially when doing Two and Three-dimensional Curved Surface(three axis), arc, lope, slots, sphere, hole, angle and screw thread processing according to customer's own design.
    1. Laser Flow Tubes
    2. Laser Flow Tubes The laser cavity filters are widely used in the development of lamp, laser, and other fields. In Beijing Zhong Cheng Quartz Glass, laser cavity filters are manufactured with high precision, strict tolerance, improved strengthened performance to guarantee the satisfied quality.
    1. Fiber End Caps
    2. Fiber End Caps Quartz end caps are manufactured using high quality quartz glass and corning, and are primarily used in high-power devices for high-power fiber lasers and amplifiers. Beijing Zhong Cheng Quartz Glass carries out special processes so that we are able to reduce the end light reflection, and ensure the output light distortion will be very small.
    1. Optical Coatings
    2. Optical Coatings High reflection coatings (HR), made from gold, silver, aluminum etc., are a kind of thin film material mainly used for light or laser beam manipulation. Metallic high reflective coatings have very high reflection at specific wavelengths or designed spectral range at specific angle or angle range of incidence.
Quartz Plate / Optical Window
    1. Quartz Plate / Optical Window
    2. Quartz window or optical glass window, a kind of transparent optical elements, are used when an optical system passes from one atmospheric environment to another.
      We also provide various AR coatings, UV/IR filter (hard coating) and high reflection coatings (HR) on optical windows.       Read more
