Baader IR-Pass 670nm Filter - 1.25" Round Mounted - FIRP-1

Baader Planetarium delivers the latest tool in the planetary imager's bag of tricks. The Baader 1.25" IR-Pass Filter blocks wavelengths below 670 nm. At these longer wavelengths, planetary images are less disturbed by wavefront distortions in the atmosphere (seeing). By combining a luminance image taken with the IR-Pass filter, along with RGB frames, overall image sharpness is significantly enhanced. Some of the world's best amateur planetary images have been taken with this technique.

The Baader IR-Pass Filter shares the same outstanding features as all the other Baader filters. High optical quality, Striae-free substrate, and high efficiency multi-coatings result in the sharpest and highest contrast image possible.

• The Baader IR-Pass Filter blocks wavelengths below 670nm.

   

• Planetary images are less disturbed by wavefront distortions at these longer wavelengths.

   

• Each Baader Planetarium IR-Pass Filter substrate is fine-optically polished plane parallel for 1/4 wavefront over entire surface.

    

• Multi-layer dielectric coatings are plasma-assisted and ionbeam-hardened using the latest technology.

    

• Coatings will never degrade from use or normal cleaning.
