Demonstration of a monolithic micro-spectrometer system

PDF Version Also Available for Download.

Description

The starting design of our spectrometer was based on a modified Czerny-Turner configuration containing five precision surfaces encapsulated in a monolithic structure. We were interested in exploring novel system designs, fabrication technologies, and examining numerous material systems, in the development of the micro- spectrometer. Our purpose at the early stages was to demonstrate the feasibility of the technology and not an attempt to address a specific sensing problem. Thus we had great liberty to select the first prototype material, which was optical quality polymethyl methacrylate (PMMA). However for most aerospace applications, more robust materials would be required such as BK7, ... continued below

Our purpose at the early stages was to demonstrate the feasibility of the technology and not an attempt to address a specific sensing problem. Thus we had great liberty to select the first prototype material, which was optical quality polymethyl methacrylate (PMMA). However for most aerospace applications, more robust materials would be required such as BK7, sapphire, quarts, etc. In addition, these materials, as well as many III-V and II-VI, would allow tremendous wavelength flexibility to support most applications. Although many of these materials can be diamond-turned, some brittle substrates require ductile-grinding with some post-polishing to achieve the desired performance.
