Colored glass absorptive filters are a kind of absorptive-type optical filter which functions by absorbing light within the rejected wavelength range. Actually, the fraction of light absorbed is a function of the thickness of the material and the amount of dye present.  

The main features of Colored glass absorptive filters includes: Cost-friendly, Insensitive to the Angle of incident(AOI) of light, High chemical resistance to contamination, fume, chemical attacks as dye is impregnated throughout the filter. NO polarization effects, Having the advantage in isolating a broad range of wavelengths, they especially do a excellent job in applications requiring the blocking of short wavelengths of light and transmission of longer wavelengths of light.

However, there are also disadvantages. If the light of incident is too intense the filters are likely to heat up and deform, therefor glass filters are not relatively very suitable for high power applications. Before placing orders, please carefully considering the wavelength range of interest, operating environment and power of incoming light. Feel free to contact us for consultancy, our experienced and professional engineer are always willing to guide you to a optimized solution.

Hangzhou Shalom EO offers optical glass filters with high durability and stability reliable under various conditions and for manifold applications. Our Standard or customized glass modules offered by Chinese suppliers are identical to that produced by SCHOTT or HOYA .
