Off-axis parabolic mirrors

Off-axis parabolic mirrors offer the advantage of unobstructed aperture and easy access to the focal plane. What’s more, their achromatism makes them particularly suitable for broadband or multi-wavelength applications. Off-axis parabolic mirrors often offer an optical solution without compromising performance, and can solve many optical design problems.

Applications include mirror collimators, mirror beam expanders, high-power laser beam focusing, MTF bench, spectrograph mirrors…

Off-axis parabolic mirror specifications include diameters up to 600 mm, non-circular shapes, off-axis angles up to 45 degrees, surface accuracy down to λ/20 @ 633 nm, microroughness typically less than 1,2 nm RMS, and a wide range of available optical coatings.
