The need for powerful reflective optics operating over a broad bandwidth has motivated the development of off axis parabolas with higher imaging performance then ever before. Within the last five years everything about OAP’s has evolved – tolerances for quality and performance, manufacturing methods, testing methods, thin film coatings and alignment technologies. AOS has re-engineered the Off-Axis Parabola for the 21st Century.
In this example, we’re going to design, position, and clock an OAP in an optical system in such a way as to provide a specified output, and then we’re going to specify the placement of the OAP relative to other optical elements in the system. This is a realistic design problem, and one that demonstrates many different, useful Zemax techniques. The article is accompanied by a zip file which can be downloaded from the last page. It contains the starting point of this design. Parabolic mirrors Parabolic mirrors produce perfect images for infinite-conjugate on-axis points (that is, for perfectly collimated light directed along the optical axis of the parabola.
For astronomical applications, we have so far used off-axis parabolae from the long list available from the Edmund's catalog. Main problem/limitation is the coating: Edmund only sells protected-Al and protected-Au; while we need protected-Ag. We are very excited to see that you offer the same type of parabolae silver-coated. Pity that you presently have only a limited choice of angles and focal lengths.
