We provide precision NIR bandpass filters with minimum angle dependency and effective blocking, Maximum
transmission capacity of the illumination wavelength (laser or LED) with excellent signal to noise ratio is required.
The filters are utilized in atmospheric monitoring, topographical, laser guiding and ranging instruments used in the
harshest environments
