Bandpass Filter against stray light

Description

Osela Bandpass-Filter

Using a bandpass filter reduces disturbing backlight and eliminates scattering light and noise to increase your signal. All filters offer an efficiency of 85%!

When we ship a filter we take care about the "blue shift". This effect comes up while the laser heats up and changes its wavelength by 0.2 to 0.3 nm per °C. The bandwidth of the filter will be selected in order to fit the application.
