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

Bạn đang xem: Toán 10"s TOAN Series Off-Axis Newtonian Collimators incorporates one of our precision, zero thermal-expansion, off-axis parabolic mirrors, interferometrically aligned in a rugged và compact housing. Twenty-one models are offered, providing unobstructed apertures from 4 to lớn 14 inches, a variety of f/numbers, và two wavefront accuracy specifications. Below is a listing of our catalog models.
