Optolong UV/IR Cut Filter

Introducing the Optolong 1.25" UV/IR Cut Filter

The Optolong UV/IR Cut Filter 1.25" is a vital accessory for astronomers and astrophotographers who demand the highest image quality from their observations and captures. Specifically designed to block ultraviolet (UV) and infrared (IR) wavelengths, this filter ensures that only visible light reaches your camera sensor or eyepiece, resulting in sharp, clear, and high-contrast images. Whether you are observing celestial objects or capturing stunning astrophotographs, the Optolong UV/IR Cut Filter enhances the quality of your results by eliminating unwanted wavelengths and preventing image distortion.

Features of the Optolong UV/IR Cut 1.25" Filter

The Optolong UV/IR Cut Filter 1.25" is engineered with advanced features that cater to the needs of professional and amateur astronomers:

• High Transmission Rates: The filter boasts impressive transmission rates: 96% at 486nm (H-beta), 95% at 496nm (OIII), 92.5% at 501nm (OIII), and 98% at 656nm (H-alpha). This ensures that key emission lines pass through while blocking unwanted UV and IR light.
• Effective Wavelength Blocking: Blocks wavelengths outside the 450-520nm and 620nm range, eliminating UV and IR light that can cause image distortion and reduce contrast.
• Superior Material Quality: Constructed with high-quality optical glass that is 1.85mm thick, providing durability and ensuring the filter does not degrade the optical performance of your telescope.
• Advanced Coating Technology: Features multi-layer anti-reflection coatings and non-cementing optical substrate coatings applied via electron-beam gun evaporation with ion-assisted deposition, enhancing durability and scratch resistance.
• Precision Engineering: The filter cell is CNC machined from aero-metal, sand-blasted, black anodized, and laser engraved for a high-quality finish that resists fading.
• Ultra-Thin Design: The ultra-thin filter cell minimizes vignetting and maximizes the clear optical aperture.
• Parfocal Design: The filter is parfocal with other Optolong filters, meaning it maintains focus when switching between filters without the need for refocusing.
• Durability: The filter is completely resistant to high humidity, scratches, and aging effects, ensuring long-lasting performance.
