Abstract

A new design and fabrication method is presented for creating large-format ( $> 100$ mirror facets) image mappers for a snapshot hyperspectral biomedical imaging system called an image mapping spectrometer (IMS). To verify this approach a 250 facet image mapper with 25 multiple-tilt angles is designed for a compact IMS that groups the 25 subpupils in a $5 \times 5$ matrix residing within a single collecting objective’s pupil. The image mapper is fabricated by precision diamond raster fly cutting using surface-shaped tools. The individual mirror facets have minimal edge eating, tilt errors of $< 1 mrad$ , and an average roughness of $5.4 nm$ .
