ZWO LRGB Filters - New version

The new  ZWO RGBL Filters  are designed to approximately equalize the flux of ASI1600 mono sensor

Better transmission, Better coating,  Better color separation

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 700-1100nm 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
