This auction is for 1 piece of Headwall Concave Holographic Diffraction Grating.
These are 1" diameter.
Originally made for use in a spectrometer. These came with some other gratings that were 1800 lines/mm, so I assume these are similar.
10 Available.
These are in good condition, may have slight coating marks on edges, but center is very clean.
Please ask if you have any questions.
Buyer to pay shipping.
Thanks for looking!
- Replica gratings from master holographic gratings recorded in concave substrates
- Perfect periodicity of grooves
- Very low stray light compared to concave ruled grating
- Grating preferably used in mountings based on Rowland circle
- slit is located in a circle equal to the radius of curvature of the grating
- allow to obtain high resolution spectrograph
- Substrate materials: Pyrex, Zerodur
