SOMABLACK is a light shading/reflection preventing film for use in optical instruments.
It has a proven track-record for many years and reliability among users for use in camera units, etc. of silver-halide cameras, digital cameras and mobile phones.


Features

  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.
  4. NR type products offer excellent reflection prevention effects comparable to pile (nap) finishing.
