Diffraction Amplitude Gratings

Black And White Gratings Product Features:

• All back white stripe amplitude gratings are produced with K9 optical glass, suitable for visible wavelength applications.


• The orientation of the grating is parallel to the short side or parallel to the change, very easy to determine the direction and installation alignment.


• We use photolithography and metal film deposition for high line width accuracy.
  Our standard B/W grating products have a period range of 10um-500um, a line width of 8um-250um, and a line pair count of 2.0-100.0 lines/mm.

Precision Grating Black and White Grating Applications:

• Industry
  In industry, black-and-white optical encoders are mainly used in the fields of precision measurement and structured light projection. In machine building, semiconductor processing and surface inspection, displacement and shape measurements can be encoded by the encoder.


• Imaging
  In imaging techniques for optical microscopy and OCT, B/W gratings can modulate stripes to enhance the visibility of tiny structures and can be used as wavefront modulation and optical interference in imaging systems.


• Research
  In the field of research, black and white gratings are usually the basic components in the laboratory, mainly used for optical experiments and optical field modulation for laser beam shaping and interference experiments.
