ZWO 1.25" CCD LRGB Filter Set Optimised for 1600MM Cameras

This ZWO 1.25" CCD LRGB Filter Set Optimised for 1600MM Cameras (3 Color Filters + IR Cut Filter) is specially designed for the ZWO ASI1600 cameras.

The new  ZWO LRGB Filters  are designed to approximately equalize the flux of the ASI1600 monochrome sensor.

It offers better transmission, better coating, better color separation and also with a clever design, there is a small spectral gap that helps to reduce the effect of light pollution.

The RGB colors combined flux will be approximately 1:1:1

• Fine-optically polished to ensure accurate 1/4 wavefront
• More than 92% transmission at passband
• Infrared wavelength 700-1100nm cut-off
• Precision off-band blocking
• Multi-layers anti-reflection coating
• Small spectral “gap” to minimize effect of light pollution
• Highly parfocal – thickness 1.9+/-0.03 mm

**Never use any eyepiece filter for solar observation without objective front filter!
