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.
Here is the the transmission curve
