Elliptical Mirror

Elliptical mirroris still a flat mirror, but the shape is cut into an oval, and the outer circle and the mirror into a 45 ° angle. When the elliptical mirror is mounted in the optical path by 45 [deg.], The optical aperture of the lens is just circular.

Elliptical mirrorsare also divided into metal coated mirrors and dielectric coated mirrors. The wide-band dielectric film reflector has a high reflectivity, and the metal film reflector has a wide reflection band.

Ellipse mirrors are typically used at 45° where a circular cross section of a given size is asked for. Our stock range of elliptical mirrors are machined from standard sheets of enhanced aluminium giving 94% reflectivity for visible applications. Generally elliptical mirrors are used as secondary mirrors in Newton telescopes or mounting in a tube where maximum aperture is required such as in perescopes.

Our stock mirrors have a guarenteed flatness of 1λ over 25mm. Where greater precision is required we offer elliptical mirrors with flatness better than λ/10 as a custom option. We also stock a range of standard front surface mirrors sheets for use in UV/ NIR and IR applications these can be cut and edged into elliptical mirrors at short notice.
