NSF Funded Study of VPH Gratings

Eight gratings are being fabricated and evaluated.

• 300 l/mm at 1064 nm

• 1200 l/mm at 532 nm

• 2400 l/mm at 532 nm

• 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.
