ZWO CCD LRGB Filter-Set 1.25" Optimised for ZWO ASI1600 and Other ZWO CMOS Cameras

CCD LRGB Filter-Set 1.25" (3 Color Filters + IR Cut Filter) specially designed for the ZWO ASI1600 cameras, but also recommended for the full range of ZWO CMOS cameras and most likely also compatible with other CMOS cameras as well.

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

The new  ZWO RGBL 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
