SVBONY 1.25" & 2" UV/IR Cut Filter

The SVBONY UV/IR Cut Filter is an essential imaging accessory for CCD, CMOS, DSLR, planetary cameras, and modified webcams. Designed to block unwanted ultraviolet and infrared wavelengths, it helps produce sharper stars, improved colour accuracy, and better focus consistency across your astrophotography setup.

Available in both 1.25" and 2" sizes, this filter is ideal for use with colour astronomy cameras, DSLR imaging trains, and telescope eyepiece accessories.

Improves Astrophotography Sharpness

By blocking out-of-focus UV and IR wavelengths, this filter reduces star bloat, colour fringing, and soft focus issues often seen with refractors, guide scopes, and colour cameras. The result is tighter stars and cleaner image detail.

Ideal for OSC, DSLR & Planetary Cameras

This is an excellent match for one-shot colour cameras, planetary CMOS cameras, DSLR astrophotography, and modified webcams. It ensures only the visible light spectrum reaches the sensor for better colour fidelity and improved focus.

Advanced Multi-Layer Coatings

Precision optical coatings provide highly effective UV and IR suppression while maintaining excellent visible light transmission. This helps preserve natural star colours and improves contrast across lunar, planetary, and deep-sky imaging.

Compatible with Most Imaging Setups

Choose from:

• 1.25" filter thread for standard eyepieces, diagonals, and planetary cameras
• 2" filter thread for DSLR imaging trains, flatteners, reducers, and larger accessories

Best Uses

• Colour CMOS astrophotography
• DSLR deep-sky imaging
• Planetary imaging
• Refractor star bloat reduction
• Modified webcam astronomy
• General visible spectrum imaging
