When used in the visible range NG glass is suitable for these purposes because filters with uniform spectral transmittance are required at various attenuation stages. We will handle from processing to filter framing.
* If you are looking for transmittance priority, please refer to this page.
Actual measurement data of transmittance (charged) can be attached. (Measurement model: Shimadzu UV-3600)
Color glass is RoHS exempted item. For related materials, please click here (English).
It is a filter that transmits only wavelengths shorter than a certain wavelength. It is used as heat absorption / cold light filter.
"SCHOTT" Color Glass Filters are classified into the following groups.
SCHOTT Color Glass stands out due to its selective absorption in the visible wavelength range. And the color glass filter's effect lies within the visible lights spectrum, so it makes the filters become a very indispensable and useful optical part in so many kinds of instrument like camera, physics and chemistry equipments etc..
