Laser line
filters are narrow bandpass filters centered on the resonance
of the laser, which attenuate the background plasma and
secondary emissions that often result in erroneous signals.
Application
diode lasers
LEDs
Instruments
Features
high transit efficiency to 70%
low wavelength shift to 1nm
low scratch loss
optical performence stable
