NSF Funded Study of VPH Gratings
Eight gratings are being fabricated and evaluated.
1200/1620 l/mm Ha/Hb multiplex grating
1200 l/mm reflection grating
2400 l/mm at 1064 nm with prism substrates
4800 l/mm at 532 nm with prism substrates
300 l/mm 10th order at 532 nm grating attempt
Some gratings will be distributed to US community at the end of this study.
