Astronomik IR-Blocking Filter - 2" Round Mounted

Astronomik IR-Blocking filters are optimally suited for when low sensitivity sensors in the UV portion of the spectrum, such as with Webcams, Meade DSI and LPI, and most video systems, are being used. With this filter placed in front of your DSLR camera, common IR induced nuisances like bright halos surrounding objects and overall image softness are completely eliminated.

When compared with transmission data from other sources, the Astronomik IR Blocking Filter is already what the majority of other manufacturers would call a UV-IR blocking filter. However, what Astronomik determines to be a "UV-IR blocker" bests any UV-IR blocker available from any manufacturer on Earth!

Optimized for systems featuring focal ratios spanning from f/0.5 to f/50, the Astronomik 2" IR-Blocking Filter has a typical transmission above 99%. It can be used in lieu of the UV-IR Blocker if your camera has low sensitivity at short wavelengths; to protect your DSLR camera or Schmidt-Cassegrain, Schmidt-Newtonian, or Maksutov telescope from dust; and, if your system does not have any refracting elements, as a substitution for the MC Clear filter.
