WebThe Cobra spectrometer shows excellent modulation transfer functions (MTF) across the entire field, while the standard lenses show significant degradation of the MTF at the camera extremes.One can see that the MTF for Cobra spectrometers are better than 80% for 50 lines/mm frequency, corresponding the Nyquist frequency of a 10 μm pixel width. WebA collimating mirror would try to collect as much light as possible on the entrance slit. How much light the instrument can collect, depends on the focal length of C, though. If it is short, it collects light from wider angles than with a long focal length, very similar to a camera lens.
