Practical Guide To Off-Axis Parabolic Mirror Alignment

opt

Drawing upon over 50 years experience in producing the most demanding high precision off-axis parabolic (OAP) mirrors - Optical Surfaces Ltd. has produced a new 10-page practical alignment guide to enable users to get top performance from their optics.

The illustrated alignment guide includes an introduction to OAP geometry as well as step-by step instructions on initial alignment ; tips to correct for errors in focus & tilt, set off-axis distance and rotation and a final alignment procedure to ensure optimised performance.

Off-axis paraboloids (OAPs), sometimes refered to off-axis parabolic mirrors or off-axis parabola, provide an unobstructed aperture allowing complete access to the focal region as well as reducing the size and minimising the weight of a design. They are especially suitable for broadband or multiple wavelength applications due to their completely achromatic performance. All together these advantages produce a cost-effective solution for many optical design problems with no compromise in performance.
