New UV/IR Blocking Filter From Baader Planetarium. Recommended For Use With CCD,
Video & WebCams For Sharper Images.

Baader UV/IR Cut Filter - Planeoptically Polished. The only infrared blocker in this price range
featuring a planeoptically polished substrate, parallel to within 30 seconds of arc!

In combination with the unique properties of the Baader Contrast Booster the resulting
spectral window eliminates all known effects of image deterioration - an absolute MUST for
digital imaging.

Properties:

* Reflects destructive heat radiation!
* Protects your valuable solar observing equipment such as DAYSTAR filters and the like
from
excessive heat stress.
* Stays cool and will not shatter if subjected to great thermal stress, since even intensive
radiation is not absorbed - as with ordinary heat protective filters, such as KG-3 or KG-5.
Energy is reflected due to an elaborate interference system of 39 dialectric coating layers.
* 98% Transmission average across the visible spectrum.
* Enables pinpoint star images with digital and CCD equipment.
* Ultrahard and durable Ion-Beam IR Cut coatings, may be cleaned anytime without fear.
* Hard and absolutely scratch resistant 7-layer multicoat featuring 0.3% residual reflection
versus the 4.6% of an uncoated substrate.
* Freedom from ghost images due to highest quality coatings.
* Planeoptically polished. Retains full image resolution even at highest magnification during
solar observation or eyepiece projection.
* Available in 1.25" and 2" size.
* Incredibly low priced
* Larger clear aperture than any competing 1.25" or 2" filter.
* Better, more elaborate filter cell design than any competing filter, featuring a CNC-milled
"crown" for ease of handling and attachment.
