4-Series Centennial Tripod

Spectrometers can also be used to test the efficiency of an optical filter in order to evaluate color neutral performance

The reduction of reflections also improves the contrast of the image by elimination of stray light

X4 CPL incorporates our state-of-the-art nanotec® Nano Coatings Technology

Our proprietary MRC coating is structurally harder than the glass itself and the reduced reflections improve the efficiency since less light is lost

As a result the X4 CPL sees a decline in IR transmission across the visible spectrum and is very well controlled throughout the IR range
