Gratings-Ronchi Rulings, Electron Microscopy Sciences
Graticules, Reticles and Grids
The grating covers the entire plate with the exception of R25, R26 and R27 where the grating occupies a 30 mm wide central strip. The glass is B270 with refractive index of 1.52.

  • Paired as light gates
  • Demonstrate interference patterns
  • Produce optical gradients

Metallic grating pattern on glass squares with opaque lines approximately 50% of the pitch. Stock items are on 50×50 mm squares of glass 1.5 mm thick.

Mutually perpendicular pairs produce a screen of square apertures. Vacuum deposited chrome gratings on glass substrate. Typically used for testing of resolution, field distortion and parfocal stability.
