Set of LRGB filters (luminance, red, green, blue) optimized for monochrome CMOS cameras.

The most important features

• better transmission, better coatings, better color separation
• allow to obtain almost equal weight in each of the channels (R: G: B about 1: 1: 1)
• 1/4 λ accuracy for the wave front
• transmission over 92% for the passband
• cut infrared in the range of 700 - 1100 nm
• a small spectral gap in the vicinity of the Hg and Na lines to minimize the light pollution effect (artificial pollution of the sky with urban light)
• filters are parfocal to a large extent - thickness 1.9 mm +/- 0.03 mm
• MC coatings
• filter holder (length): 5.5 mm + 3.5 mm thread
• thread: M28.5x0.6
• Size: 1.25 "/ 31.7 mm
