Paper Abstract

Within this paper, we present a novel approach for an optical system for a near infrared (IR) line camera, which exists of only one monolithical optical element with 3 optical free form surfaces. The optical design was performed with respect to the following requirements given by the application: wavelength range 0.9 μm to 1.7 μm, field angle 75° x 2°, horizontal angular resolution 0.5°. Within the design process one of the three optical surfaces is formed biconic, two are realized as cylindrical surface. The calculated component was realized by means of diamond UP manufacturing. Two of the optical surfaces were metallized to work as mirrors for the above mentioned spectral range. The realized element has a size of less than 8 cm3; it was finally characterized.
