Band Pass Optical Filters

Sofradir IR Viewers are nearing the end life as a product line.
We can offer an alternative though, so please contact us!


Band Pass Filters


These optical filters are perfect for many imaging applications that benefit from blocking the transmission of electromagnetic radiation while allowing a specific band of radiation to pass through.

Features

  • Narrow bandpass in near-infrared band
  • Excellent in-band transmission
  • Sharp transition assures precise blocking(typical)



Specifications


Diameter
25.4mm +0.0/-0.25mm

λc = Cut-on wavelength at which transmission is 50% Tpeak
HW = Half-width at 50% Tpeak
Tpeak = Minimum Peak Transmission in (%)
Brange = Blocking spectral range with OD# blocking of spectral range except for band pass
OD = Attenuation of transmittance by 10OD
