MRC16 Coating

Breakthrough's state-of-the-art multi-resistant coating (MRC) is an optical coating applied to both surfaces of the glass disk to reduce reflection and to increase surface durability. Breakthrough's proprietary MRC coating is structurally harder than the glass itself and the reduced reflections improve the efficiency since less light is lost. The reduction of reflections also improves the contrast of the image by elimination of stray light. The real world result? Better contrast and color.

Low light transmission and green flaring are common problems with uncoated glass. As MRC coatings are added to each side of the optical disk light transmission steadily increases with flaring steadily decreasing. In our lab tests light transmission apexes at about 16-layers of MRC, and slowly decreasing in transmission at 18 and above. 8-layers of MRC are applied evenly to both sides of each optical disk resulting in MRC16.

Worlds Most Color Neutral ND Filter. 100% Guaranteed.

Most of the neutral density filters on the market exhibit a strong blue or magenta cast. The higher the ND factor the more pronounced the color cast. To achieve the most color neutral ND performance, Breakthrough developed an alternative manufacturing method to the conventional oven process.

A breakthrough design with traction.

Constructed of high quality brass CNC machined with Breakthrough's signature traction frame, the X4 ND is easier than ever to attach and remove securely, even with gloves on in cold conditions. The X4 ND is specifically designed be a workhorse ND filter for field work, built to withstand extreme wind, salt water, dust and other abrasive conditions and elements.
