Concave parabolic mirrors are frequently used to accurately collimate point sources of visible and IR radiation. However, precise alignment is required to obtain optimal performance, and lengthy set-up times may be encountered, especially if the mirror is frequently moved.

SORL's TOAN Series Off-Axis Newtonian Collimators incorporates one of our precision, zero thermal-expansion, off-axis parabolic mirrors, interferometrically aligned in a rugged and compact housing. Twenty-one models are offered, providing unobstructed apertures from 4 to 14 inches, a variety of f/numbers, and two wavefront accuracy specifications. Below is a listing of our standard models.

Features

Strict attention has been paid to mechanical configuration and stability of the TOAN Series. Combined with SORL's dedication to quality in optical fabrication and superior test capabilities, the result is reliability and performance unparalleled by similar units commercially available today. The optical path is baffled, minimizing extraneous radiation which can limit signal-to-noise performance.
For applications in the visible and near-infrared, higher quality systems can provide a lambda/4 wavefront, as tested at 632.8 nm. Enhanced aluminum coatings to improve visible transmission and complete interferometric data are supplied.
