U19515 Set of 4 gratings
6/03 ALF
®
Transmission gratings for spectroscopic examinations
and for experiments on diffraction and interference.
1. Safety instructions
• To avoid scratching or soiling the surface of the grat-
ing, hold the slide only by its edges.
2. Description, technical data
Four line gratings mounted in slide frame with protec-
tive glass plates. Useful for students and demonstra-
tion experiments to study the relation between line
spacing, angle of diffraction and wave length.
Dimensions: 50 mm x 50 mm
Projection aperture: 24 mm x 35 mm
No. of lines: 80, 100, 300, 600 lines / mm
Grating constant: 12,5 µm, 10 µm, 3,3 µm, 1,7 µm
