LDF-NB Series

Lights for Interference Fringe Inspection LDF-NB Series
Lights that make coating presence or unevenness on thin film visible

* Interference fringes: Alternating bright and dark bands that can be observed when light is reflected from the top and bottom layers of a thin film.

Features

Features

  • Replacement for fluorescent lights and sodium vapor lamps
  • CCS unique optical technology enables lower speckle noise*1
  • Four emission colors (red, green, blue, RGB) available to suit individual needs

*1 Speckle noise is a typical phenomenon associated with laser diodes.
