ZWO New 1.25inch LRGB Filters for CMOS camera

ZWO New LRGB Filters for CMOS Cameras

The new ZWO LRGB Filters are specially engineered to balance the flux captured by CMOS camera sensors, providing:

• Better color separation

• Improved transmission efficiency

• Enhanced anti-reflection coating quality

Technical Specifications

• Name: ZWO New LRGB Filters optimized for CMOS cameras (Set of 4 filters)

• Size: 1.25″

• Thickness: 5.5 mm + 2.5 mm (thread)

• Thread: M28.5 × 0.6 male

• Key Features

  • RGB color combine weights designed to be approximately 1:1:1 for balanced color capture

  • Fine-optically polished glass ensuring accurate 1/4 wavefront quality

  • High transmission: More than 92% within the passband

  • Infrared cut-off: Blocks 700–1100 nm wavelengths

  • Precision off-band blocking for minimal contamination

  • Multi-layer anti-reflection coating to reduce reflections and increase contrast

  • Minimal spectral gaps to reduce light pollution effects

  • More parfocal: Glass thickness precisely controlled at 1.9 ± 0.03 mm
