Abstract

High performance infrared lens used in aerospace optical remote sensing systems have great benefit in resource exploration, pollution monitoring etc. However the high technical threshold of manufacture, the production and launch cost due to the heavy infrared optical materials, and the long period of alignment have restricted its use especially for civil and commercial aerospace. Here we present a realization of aerospace infrared lens for mass production. An unique opto-mechanical structure design has been implemented in order to meet the requirements of the mass production of space infrared lens. Some high effective, low cost processing technology are used both for optical and mechanical parts. The produced lenses have the biggest diameter of 300mm and the best RMS of λ/50(λ=632.8nm). A smart alignment based on an online device with lens alignment and image quality measurement reduces the period from 30 days to 7 days. With the well assembled infrared lens, the space camera has a system wavefront of 0.1λRMS (λ=3.39μm) and the MTF of 0.38(@25lp/mm).
