Many optical systems - especially refractors and camera lenses - allow ultraviolet (UV) and infrared (IR) light to pass through unobstructed. But these wavelengths are not focused on the same plane as visible light, leading to blur, color shifts or blurry stars.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This filter blocks both UV light (below ~400 nm) and IR radiation (above ~700 nm), while allowing the full visible spectrum to pass through. This allows you to maintain true-to-life colors, sharper details and better focus in your images. The filter is therefore ideal for use with CCD and CMOS cameras, especially when photographing with APO refractors or fast lenses.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The 1.25\" version is compatible with any standard eyepiece, camera adapter, or filter wheel. The optical glass is multi-coated for maximum transmission in the usable range and minimum reflections.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Advantages<\/strong><br>\u2713 Blocks both UV and IR outside the visible spectrum<br>\u2713 Improves sharpness and focus in color cameras<br>\u2713 Preserves color fidelity in astrophotos<br>\u2713 Reduces halos and color shifts around bright stars<br>Fits all 1.25\" accessories and filter wheels<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Specifications<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Type:<\/strong> UV\/IR Cut-off filter<\/li>\n\n\n\n<li><strong>Connection:<\/strong> 1.25 inches (31.75 mm)<\/li>\n\n\n\n<li><strong>Transmission:<\/strong> Passage from 400-700 nm, blocking beyond that<\/li>\n\n\n\n<li><strong>Mounting:<\/strong> Aluminum, black anodized<\/li>\n\n\n\n<li><strong>Coating:<\/strong> Multiple anti-reflective<\/li>\n\n\n\n<li><strong>Application:<\/strong> Astrophotography with color cameras and refractors<\/li>\n\n\n\n<li><strong>Not suitable for:<\/strong> Narrowband use or emission line isolation.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Observation goals<\/strong><br>The Omegon UV\/IR Cut-Off Filter 1.25\" is designed for photographers working with a color camera or DSLR in combination with lenses or telescopes that are sensitive to chromatic aberrations.
