Filters are designed by their manufacturers to transmit or absorb different wavelengths of light. Optical Filter is widely used in medical instrument, finance, metallurgical, photography,cameras, navigation, military, biography instrument, optical instrument and science field etc.
Longpass filters are designed to have a sharp transition from reflection to transmission, making them ideal for various applications. Available in a variety of cut-on wavelengths, these filters are designed for fluorescence and order sorting applications.
China star optics can supply a full range of filter. They are shortpass, longpass, band pass, ultraviolet, infrared, heat absorbing, 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.
