ZWO New LRGB Filters for CMOS camera

The new ZWO LRGB Filters are designed to approximately equalize the flux of CMOS camera sensor.

Better transmission, Better coating, Better color separation

Technical Parameter:

Name: ZWO New LRGB Filters Optimized for CMOS camera (4 filters)

Size: 1.25″

Thickness: 5.5 mm+2.5 mm(thread)

Thread: M28.5*0.6

the RGB color combine weights will be approximately 1:1:1

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