Silicon immersion gratings and their spectroscopic applications
Witryna20 paź 1993 · 20 October 1993. Physics. An immersion grating with a high refractive index, n, increases the spectral resolution by a factor n over that of a reflective surface grating of equal length. A silicon immersion grating has been developed and tested; initial results are reported here. View on SPIE. Witryna26 cze 2016 · Abstract. We have explored a number of lithographic techniques and improvements to produce the resist lines that then define the grating groove edges of silicon immersion gratings. In addition to our lithographic process using contact printing with photomasks, which is our primary technique for the production of immersion … chip hitman pro
Immersion grating and etched gratings for infrared astronomy
Witryna18 paź 2016 · TOKYO, October 18, 2016—Canon Inc. announced today the successful development of the world’s first * indium phosphide (InP) immersion grating. † Strengthening its lineup of immersion gratings, which includes gratings made from germanium (Ge) and cadmium zinc telluride (CdZnTe), Canon is contributing to even … WitrynaThe FIRST silicon immersion grating, with 54.74 degree blaze angle and 16 l/mm groove density, has been fully characterized in the lab. The 50x50 mm square grating entrance pupil is coated with a single layer of anti-reflection coating resulting in a 2.1% measured reflection loss. The grating surface was coated with a gold layer to … Witryna10 lut 2024 · The immersion grating of claim 1 where the at least one dielectric layer is characterized by a thickness between 0.55 μm and 0.7 μm. 12.
