Systems design involves the combined use of optical elements, lens assemblies, lasers, modulators, gratings, scanners and other elements to perform a specified function. All optical systems including the eye, 35 mm or digital camera, telescope or FLIR have the following block diagram: a light source, a beam shaping or imaging optical system and a final image plane.
The light source may be a laser, reflected light or intrinsic radiator while the image plane can be a CCD, the retina, photographic film or just a substrate that is “marked” among others. The optical system is everything in between to get the light to the image properly. Even for non-imaging systems, the basic block diagram holds even though there is no “image” in the usual sense.
Typically, these components are mounted and aligned on some kind of optical bench or other mounting structure in order to register these components with respect to each other. To assure a robust system that performs to specifications requires strong knowledge of optical systems design and the interaction of various components and sub-assemblies.
Good system design requires understanding the effects of misalignment and concurrent development of a suitable alignment method. Andorra has been extensively involved in optical systems design, alignment and testing for many complex systems in printing and data recording, test benches, spectrometers, and diffuse light illuminators among others.
