Diffraction grating, 100 lines/mm
Grating copy encapsulated between two glass plates for protection and flatness. Active grating area approx. 45 × 30 mm; total glass plate size approx. 63.5 × 48 mm. The grating constant (100 l/mm) gives clearly separated diffraction maxima when using common light sources and lasers.

Optical gratings, 3-in-1
This set consists of three original gratings from Paton Hawksley with 100, 300 and 600 lines per mm respectively. The gratings are mounted between plane-parallel glass plates in a cardboard frame of 90 x 30 mm. The middle grating corresponds to 7500 lines per inch, which gives an accurate line count of 295.28 lines per mm. Each grating has an area of 9 x 16 mm.
