Astronomy Monocular Filter UV IR Cut For Astronomical Telescope Outdoors

Description

Astronomy Monocular Filter UV IR Cut For Astronomical Telescope Outdoors
SVBONY produces the world's finest UV/IR cut filter.  it use has become the defacto standard for imagers around the world.  This filter is a must for all digital imaging with Digital Cameras, CCD/CMOS Cameras, and WebCams. Also useful for protecting valuable H-Alpha filters from heat stress and damaging IR (Daystar, etc). Due to their extremely high optical quality, these filters may be stacked and used far in front of the focal plane (necessary for imaging uses). The UV-IR-Cut filter uses the very latest coating technology, to deliver the finest filtration quality - and lifetime durability.
★Extremely Sharp Cutoff at 680nm (leaves all the visible red, including the important 656nm H-alpha emission line).
★Sharp cutoff below 420nm. Eliminates violet halos around bright stars (more effectively than simpler so-called Minus Violet photographic filters).
★True optical quality glass substrate and coatings. Why spend all your money on quality primary optics - only to place a lower grade filter optic in the path?
★Combine with any of the other SVBONY filters, to deliver the sharpest images possible.
★Reflects destructive heat radiation!
★Protects your valuable solar observing equipment such as DAYSTAR-Filters and the like from excessive heat-stress (ie, from cooking the immersion liquid!)
★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”.
★Enables pinpoint star images with digital and CCD- equipment.
★Ultrahard and durable Ion-Beam IR-cut coatings, may be cleaned any time without fear.
★Non-aging sealed coating edges
★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.
★Low priced
★Better, more elaborate filter cell design than any competing filter, featuring a CNC-milled “crown” for ease of handling and attachment.
Improve image sharpness with the addition of an UV-IR Cut Filter, which blocks Ultraviolet and Infrared transmissions but lets the visible spectral region shine through. The IR (700nm to 1100nm) and UV (300nm - 400nm) part of the spectrum are invisible to human eyes, but not to most CCD and other digital cameras, which are sensitive to 300nm to 1100nm. With the UV-IR Cut filter installed, violet halos and an overall soft image are a thing of the past. This filter also reflects heat radiation and provides great protection against dust. The 36mm Unmounted UV-IR Cut Filter is made with glass that has been multi-coated with an ion-assisted deposition technology to ensure scratch resistance and stability on the central wavelength, or CWL. This UV-IR Cut filter is designed to be used with color filter wheels that accept 36mm Unmounted filters. 95% transmission at visible spectral region 420-680nm highly passing the major nebula emission lines of H-Alpha 656nm, SII 672nm and NII 654nm and 658nm. Ultraviolet 300-400nm and infrared wavelength 700-1100nm cut-off. Each filter comes with a plastic case with high pressure EVA
