The Blue Photographic Filter is a high contrast Blue filter suitable for CMOS and CCD sensors. This filter is IR-blocked.
Parfocal LRGB Filters
Broadband filters are parfocal which ensures that you will not have to refocus when you quickly switch filters to capture images.
Multi-layers anti-reflection coating ensure no halos, ghosting or reflections. Filters are resistant to scratches and do not get affected by temperature change.
Equal Weight on RGB Filters
RGB color combine weights are 1:1:1.
Limit Sodium Light Pollution
A gap between green and red filters blocks out the primary Sodium light pollution line at 589nm and improves color balance and separation.
Filters have been designed to allow max transmission for true original, natural color imaging.
