Design, calibration and assembly of an Offner imaging spectrometer

We present a rapid and efficient method of design, assembly and calibration of an Offner dispersive imaging spectrometer. Experimental results are described from a laboratory prototype that was built adapting an analytic model to an experimental design. This imaging spectrometer has a spectral range from 400 nm to 1000 nm, 245 spectral bands and an f number of 2.4. Therefore, this work allows high optical quality and low cost imaging spectrometers to be built.
