Astronomik - UV/IR Blocking Filter Canon EOS Clip

UV and IR cut Filter for digital photography.
The Astronomik UV-IR Blocker lets the full range of sensitivity of the human eye (according to DIN 5031) pass, and blocks all
other parts of the spectrum in the UV and IR. The Astronomik UV-IR Blocker is the ideal choice as a luminance filter for any kind
of digital photography.
Because of the perfect blocking of UV and IR all optical problems in these parts of the spectrum are avoided.
The filter is optimized for systems with focal ratios between f/0.5 and f/50. The typical transmission is higher than 99%.
Main use
The UV-IR Blocker gives you a perfect parfocal filter for the luminance channel. It is also great as a dust protection for
your telescope and camera. Other uses

As a dust protection of Schmidt-Cassegrain, Schmidt-Newton or Maksutov system or as a dust protection in front of DSLR
camera. 
As an alternative instead of the IR-Blocker if your camera has a high sensitivity at short wavelengths. 
As an alternative instead of the MC Clear if your system has any refracting elements

Alternatives
You should think about using the IR-blocker if your camera has a low sensitivity at short wavelengths. Think about using the
MC Clear glass if you have a system without any refracting elements. If you do color imaging from light polluted places, please
think about using the CLS CCD filter for the luminace data instead!
