This new set of 4 LRGB filters is mounted in 2" barrels and it is specifically designed for full frame cameras such as the ASI 6200.

The L filter is an IR-UV cut filter for the luminance. 

The filters are parfocal so there is no need to refocus when the filter changes. The surfaces of the filters are optically polished and fully multi-coated. 

Each filter cuts off the ultraviolet and infrared violet so there is no need to use the L filter in combination with the colour filters.
