ZWO LRGB Filter Set 36mm, unmounted

ZWO LRGB Filter Set 36mm, unmounted

Four multi-coated interference filters. Optimized for imaging with monochrome CMOS and CCD cameras. It consists of:

♦ 36 mm interference filter red, green, blue
♦ 36 mm UV/IR block filter

This filter set is an interesting alternative to the significantly more expensive filter sets from other manufacturers on the one and to simple colored glass filters on the other hand. Compared with the latter, the ZWO filters offer a brighter and more contrasty image. The ZWO LRGB  36mm filter has 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 2mm

Technical Parameter:

Name: ZWO LRGB  36mm filter(4 filters)

Size: 36mm

Thickness: 2mm

Optimized for ASI cameras, these filters can also be used with Atik or Moravian systems.
