950nm Bandpass Filter,IR glass filter

Bandpass filters transmit light only within a defined spectral band ranging from less than one to many nanometers wide.It's preferable to monochromators because of their higher transmission and better signal-to-noise

1) specially designed for 950nm LED or Laser light source

2)deeply block the other spectrum, no visible red light transmittance, which makes the LED light source completely invisible.

3)Standard or customized features with different functions for the special applications
