Diffraction Grating Slides
These Holographic Diffraction Gratings are highly efficient embossed Holographic Optical Elements (H.O.E.). The quality of the spectrum produced from these gratings is the brightest possible with the minimum of distracting visual noise. Each grating is mounted in a ridged cardboard frame allowing ease of handling and use.
The slides are available as 500 and 1000 lines/mm linear gratings, or 200 lines/mm for the double axis grating.
With these you can:
Physical dimensions (same as a 35mm projector slide)
Frame Size: 50mm x 50mm
Active Area: 35mm x 24mm |
