Spectrum filter, for shallow to medium depth, for Nauticam WWL-1

The Spectrum Filter M2 for the Nauticam WWL-1 wet lens is designed for medium depth and converts the ambient light to white light within a depth range from about 5 to 12 meters. 

This filter can be changed underwater. It is placed between the Nauticam WWL-1 wet lens and the flat port on the camera housing. Two notches at the edge of the filter indicate that it is a M2 type filter.

The above CIE color coordinates diagram shows how the color coordinates of the ambient light are shifted to the region of white light. A perfect match with daylight is at about 7.5m depth. A this depth the color coordinates of the filtered light corresponds to about 6000 Kelvin.
