Quartz Glass Laser Flow Tubes/ Laser Cavity Filters/ Laser Reflectors
Beijing Zhong Cheng Quartz Glass can produce different size of laser cavity filter according to customer’s requirement.
Custom Range- Single or multi-hole
- Inner diameter range：10-300mm
- Materials: Based on the different block of UV light and other required properties, materials available are as below:
Borosilicate glass (Pyrex glass)
Synthetic fused silica
Fused quartz
Cerium Doped Quartz
Europium Doped Quartz
Ti Doped Quartz
Samarium Doped Glass - Available surface coating: silver, aluminum, gold, etc.
The ceramic reflector body is made with 99% Al2O3, and the body is fired at an appropriate temperature to achieve the appropriate porosity and strength. The surface of the reflector is fully coated with high reflectivity ceramic glaze. The biggest advantage compared with the gold-plated reflector is that it has a very long service life and the reflection characteristic is diffuse reflection.
Main Features
1. The surface is fully glazed for maximum reflectivity and easy to clean.
2. The reflectivity reaches 97% at the wavelength of 600-1000nm.
3. The reflectance efficiency exceeds 95% in the 400-1200nm spectrum range.
4. The green body has proper porosity and high strength.
