Zeiss T* CSC Filter 72mm – Curved CSC interference design cuts UV and IR and prevents green/cyan color casts

The Zeiss T* CSC Filter 72mm uses a curved CSC interference design to reduce unwanted UV and IR light while avoiding the green and cyan color casts that can appear with some filters. You will notice these issues most often with wide-angle lenses, and this filter addresses that specific problem.

Design and construction

The filter is constructed as a two-component system. It pairs a negative and a positive optical glass element with equivalent refractive power. Between these glass elements, Zeiss places a dedicated filter layer. As a result, light rays pass through the assembly while remaining straight.

Optical performance

Because of the curved CSC interference construction, the filter cuts off UV and IR components almost completely. At the same time, it preserves natural-looking colors by preventing the green and cyan casts that can occur—especially when using wide-angle lenses.

Key features

  • Curved CSC interference filter design.
  • Two-component construction: negative and positive optical glass with equivalent refractive power.
  • Intermediate filter layer that keeps light rays straight.
  • Effectively cuts off UV and IR components almost completely.
  • Reduces green and cyan color casts, particularly noticeable with wide-angle lenses.

FAQ

Question: Will this filter help with color casts on wide-angle lenses?
Answer: Yes. The curved CSC interference design specifically avoids the green and cyan color casts that are often noticed with wide-angle lenses.

Question: How does the filter keep light rays straight?
Answer: The filter pairs a negative and a positive optical glass element with equivalent refractive power and places a filter layer between them. This construction maintains straight light rays through the filter.

Question: Does the filter block ultraviolet and infrared light?
Answer: Yes. The curved CSC interference filter cuts off UV and IR components almost completely, reducing their impact on the image.
