Narrow Bandpass and Laser Line Filters
These filters are narrow bandpass filters centered at the specified
centre wavelength (CWL, which can be a laser line). They are used to reject the background plasma and secondary
emissions that often result in erroneous signals in spectroscopic
measurements. In the case of diode lasers and LEDs, these filters can be
used to make the light output more monochromatic. Newlight Photonics
bandpass filters provide a very high peak transmission with steep edge slopes
for maximum spectral noise rejection.
