Catadioptric Lenses

Overview

Most of the lenses in this range provide a diffraction limited performance over the total field of view and spectral range for which they are designed. The images are large (>10mm diameter) and because the performance is diffraction limit, they can be used with any CCD to a maximum of 2/3”.

These lenses have been ruggedised and a-thermalised to maintain performance specification over a temperature range of at least -20°C to 60°C.

Special care is taken in the mechanical design to provide effective baffling, thereby minimising glint and the “white-washing” of images when bright sources such as the sun illuminate the front of the lens.

Every lens is tested and the measured MTF graph is supplied with the lens. Note that due to manufacturing tolerances the actual MTF performance is typically 5 to 10% lower than the design graph.

NOTE: CHROMAR Technology preserves the right to change any design or specification in order to improve a product or to more closely reflect actual performance, however, all effort will be made to maintain form and fit while improving function and performance.
