SOMABLACK FILM is a light shading/reflection preventing film for use in optical instruments.
High lights shading type [H type] of high optical density films for light shading parts like shutters and diaphragms used in optical equipments such as cameras. It has long time performance records and reputation.


  1. It is made of a polyester film in which carbon black is mixed, and has excellent dimensional stability and good for punching work.
  2. With double-side sand-matte finishing, light reflectance is lowered, and further by special coating, electrical conductivity and sliding property are given.
  3. H type products particularly have high light-shading property which is comparable to silver-halide cameras.
