ABSTRACT:
A spectrometer construction is shown in which the chassis of the spectrometer is fabricated by stamping, punching, and bending sheet metal. The mirror supports and other elements are also formed from sheet metal. Precision locations are assured by tab and slot, or half-shear and recess, matching of the sheet metal parts. The mirrors in the spectrometer (other than those in the interferometer) are secured directly to vertical sheet-metal walls without intervening adjustments. The mirrors have unitary reflection and backing structures formed either by a diamond-cutting lathe, or by precision plastic molding. The same mirror locating means are used both during formation of each curved mirror surface and also in assembling of the mirror body in the spectrometer.
