UG1-ZWB2 Ultraviolet optical glass
Product description:
Nantong Haisheng Optical Co.,Ltd. can supply full range of filters. They are short pass Filter, long pass Filter, band pass Filter, ultraviolet Filter, infrared Filter, heat absorbing Filter, and color temperature conversion filters. We use material by China to Schott, Hoya, and other manufacturers to process them. Metallic films, colored glasses and thin dielectric films filter are all available per your requirements.
Filters are designed by their manufacturers to transmit or absorb different wavelengths of light. And they are widely used in scientific experiments and industrial applications where that change is necessary.
