TS Optics 2'' IR and UV blocking filterBlocks IR and UV light for improvement of contrast during imaging
A superb filter that blocks infrared and ultraviolet light. The filter
has the 2" filter thread on both sides. The optical quality is
excellent, the surfaces are precisely polished. The filter has a
dielectric coating which also improves longevity and resilience of the
Webcam and CCD sensors can detect UV and IR light. However the telescope
lenses, barlow lenses, image correctors etc are not corrected for light
outside the visible part of the spectrum. The result of this is an
image that lacks contrast and sharpness.
By using this filter you can eliminate this negative effect entirely.
Whenever any lenses are between the object and the camera the filter
should be used. (Telescope objective, SC corrector plate, eyepiece,
barlow, image corrector...).
The filter is also recommended for solar observing with Herschel prisms,
since these transmit a significant amount of UV and IR light which
would damage your eyes.
The filter alone does not substitute a solar filter. For solar observation, you definitely need a sun filter.Delivery contents
