ZWO 31mm LRGB Filter Set
The ZWO 31mm LRGB filters are enhanced by multiple layers of anti-reflection coatings. The four filters in this set are fine-optically polished to reach an accuracy of 1/4 wave.
Perfect for the ZWO EFWMini or EFW8, and will work fine on any filter wheel that accepts 31mm unmounted filters! This affordable imaging filter set includes four 31mm 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 700-1100 nm infrared wavelength cut-off. There is a spectral gap in these filters that will minimize the effects of light pollution.
