Grating prisms (grism) designed for near-infrared spectroscopy typically make use of high-refractive index materials such as zinc selenide (ZnSe), at the expense of large Fresnel losses ( 18%). Part of the loss can be recovered by using anti-reflecti

ZnSe has a high refractive index (n~ 2.45) and low optical loss (< 0.1/cm) from 0.8 to 12 um. Therefore ZnSe immersion gratings can enable high-resolution spectroscopy over a wide wavelength range. We are developing ZnSe immersion gratings for a grou

We diamond fly cut 2 sets of germanium grisms for the LMIRcam 3-5 micron Fizeau imager for the combined focus of the Large Binocular Telescope (LBT). The grisms mount in a filter wheel near a pupil to enable moderate resolution (R~300) spectroscopy.

The WINERED spectrograph requires a large (9 cm × 9 cm aperture), 70° blaze ZnSe immersion grating to achieve a resolution of ~100,000. It will be implemented as a mosaic of 3 gratings of aperture 3 cm × 9 cm. LLNL is diamond machining a subscale
