WebOct 23, 2001 · We discuss the design and performance of TEXES, the Texas Echelon Cross Echelle Spectrograph. TEXES is a mid‐infrared (5–25 μm) spectrograph with several operating modes: high resolution, cross‐dispersed with a resolving power of R = λ/δλ ≈ 100,000, 0.5% spectral coverage, and a ∼1.″5 × 8′′ slit; medium resolution, long‐slit with … WebEchelle grating. An echelle grating (from French échelle, meaning "ladder") is a type of diffraction grating characterised by a relatively low groove density, but a groove shape which is optimized for use at high incidence angles and therefore in high diffraction orders. Higher diffraction orders allow for increased dispersion (spacing) of ...
