Gentec-eo UV Bandpass Filters and IR Filters. Wavelength management using coloured glass filters for UV and IR applications.
UV Bandpass Filter
We offer a coloured glass filter specifically designed for the UV spectrum. Depending on the
wavelength, the UG11-UV filter
transmits 20% to 70% of the input beam power. It is particularly useful for applications with wavelengths between 250nm and 370m, Other wavelengths are blocked by the filter.
IR Filter
The B3-IR-Filter coloured glass filter is specifically designed for IR applications. Acting as a
longpass filter,the B3-IR-Filter cuts all wavelengths below 1250nm and only lets the
IR wavelengths pass through.It transmits approximately 70% of the incident light.
