Abstract

Image mapping spectrometer (IMS) allows to obtain 3D (x,y,λ) datacubes instantaneously in a snapshot mode. It has a wide range of applications, including cell signaling, cancer diagnostics, and retinal imaging. The key component, multifaceted mapping mirrors, were fabricated by diamond machining, which have issues causing the variant intensity of facets and limited spatial samplings. Here we present an entirely new fabrication technique using lithographic Two-Photon Polymerization (2PP). A pixelized mapping mirror with an aluminum coating was designed and fabricated to overcome the challenges brought by prior mapping mirrors. A prototype IMS was set up on the bench to show preliminary fluorescence hyperspectral images.
