Economical Optical Flat

For the illumination optical system and a simple experiment, it is the glass substrate of which high surface quality used for the optical element is not required. Surface accuracy and parallelism (tolerance of wedged) is the same as optical flats for a laser.

  • It is also available for manufacturing with a coating as requested to the plane substrate.
  • In additional to the circle, square type, rectangular type of planar substrate, it is also available a wedge substrate and the parallel planar substreae which has high surface accuracy of both side.
