ZWO 36mm LRGB Filter Set 

ZWO's 36mm LRGB Filter Set is ideal for the ZWO EFW7. This filter set also works perfectly on any filter wheel that takes 36mm unmounted filters! This high-performance imaging filter set features four 36mm filters: Luminance (UV-IR Cut), Red, Green, and Blue. At passband, each filter delivers over 92% light transmission and has precision off-band blocking and a 700-1100nm infrared wavelength cut-off. There is a spectral gap in these filters that will minimize the effects of light pollution.

The ZWO 36mm LRGB filters are fine-optically polished to reach an accuracy of 1/4 wave. Their performance is further enhanced by multiple layers of anti-reflection coatings.
