UV/IR-CUT filter
. . . . Rs.
5,700.
The only infrared blocker in this price range featuring a
plane optically 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.
*Reflects destructive heat radiation.
*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 dielectric coating layers.
*98% Transmission average across the visible spectrum.
*Enables pinpoint star images with digital and CCD-
equipment.
*Ultra-hard and durable Ion-Beams IR-cut coatings, may be
cleaned ant time without fear.
*Hard and absolutely scratch resistant 7-layer-multicoat
featuring 0.3% residual reflection versus the regular 4.6 % of an uncoated
substrate.
*Freedom from ghost images due to highest quality Coatings.
*Plane optically polished! Retains full image resolution even at highest
magnification during solar observation or eyepiece projection.
Most effective when used with larger, fast focus telescope in a light polluted sky. These filters dramatically improve image contrast by removing most of the "noise" or ambient light from the background sky. Light from natural oxygen emission, ionized mercury and sodium (vapor lamps) are selectively removed, while emission nebula wavelengths are allowed through. The effect of the filter is that nebular light reaching the eye is observed visually in dramatically increased detail, while the effects of unwanted
city light are greatly reduced
31.7mm (1.25") Eyepiece filter.
