Immersion grating coating
WitrynaE-coat is a unique immersion coating process in which electrically charged particles are deposited out of a water suspension to coat a conductive part. Electrocoating market … WitrynaHere, we present a novel method to fabricate long period gratings using standard single mode optical fibers (SMF). These optical devices were fabricated in a three-step process, which consisted of etching the SMF, then coating it with a thin-film and, the final step, which involved removing sections of the coating periodically by laser ablation.

WitrynaPaper Abstract. Silicon immersion gratings (SIGs) offer several advantages over the commercial echelle gratings for high resolution infrared (IR) spectroscopy: 3.4 times … WitrynaOur Ge immersion grating has dimensions of 49 × 41 × 155 mm as shown in the top panel in Fig.1 (a). The blaze angle is 75 ° and the lattice constant (groove spacing) is 476 μm. The diffraction surface is Au-coated to maximize the diffraction efficiency. The input facet of the immersion grating is AR-coated to cover the whole
WitrynaMore specifically, the immersion grating disclosed herein may be used to narrow the spectrum of light emitted by excimer laser systems. Narrower spectral linewidth of excimer laser systems may enable the creation of smaller feature sizes in semiconductor structures manufactured using UV photolithography processes. ... Anti-reflection … WitrynaSilicon immersion gratings (SIGs) offer several advantages over the commercial echelle gratings for high resolution infrared (IR) spectroscopy: 3.4 times the gain in dispersion or ~10 times the reduction in the instrument volume, a multiplex gain for a large continuous wavelength coverage and low cost. We present results from lab characterization of a …
WitrynaSince an immersion grating provides n (n: refractive index of its material) times higher spectral resolution compared to a conventional reflective grating of the same size, an immersion grating is a powerful optical device for the infrared high-resolution spectrometer. Recently a high-resolution spectrometer in the infrared wavelength … WitrynaAn immersion grating includes a dielectric substrate having an incident light surface and a second surface opposing the incident light surface. ... When metal is used as a coating to provide high- efficiency diffraction from the grating, the light is incident from the air and reflectively diffracts off the metallic grating structure, never ...
