Fabrication of Metal Mirrors for Far-Infrared Wavelengths.

Abstract

A simple machining procedure has been applied successfully to produce metal mirrors suitable for far-infrared wavelengths. Ninety-degree off-axis paraboloidal or ellipsoidal mirror sections may be cut from brass or aluminum by means of a series of pre-determined increments on a conventional laboratory lathe. Paraboloidal mirrors with low f-numbers (f/2) have been used with good results as part of the collecting optics of a far-infrared heterodyne receiver. (Author)
