The Offner spectrometer was the first such instrument; it has almost exclusively been employed on satellite platforms, and has had little impact on ground-based instruments. WebbOffner design is employed, where orientation of the two mirrors is slightly asymmetric. This configuration offers a larger field of view and lower aberrations. These spectrometers have a concentric structure and thus a compact design. They operate with a relatively low F-number ( ≤f/2), meineke credit card approval odds
