Parfocal LRGB Filters

Broadband filters are parfocal which ensures that you will not have to refocus when you quickly switch filters to capture images.

 

Anti-Reflection Coatings

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 Polution

A gap between green and red filters blocks out the primary Sodium light pollution line at 589nm and improves color balance and separation.

Luminance UV/IR Cut filter

The Luminance UV/IR Cut filter is designed for ultraviolet and infrared wavelength blocking to improve sharpness of the image and reduce halos on lens optical systems.
It can be used on a CMOS and CCD cameras which do not have an IR protection filter toward an image sensor or were remodeled (DSLR, Mirrorless).
This type is required to unfiltered CCD and CMOS sensors as they are extremely susceptible to UV and IR rays just outside the visible spectrum can have a very negative impact on image quality.
