Dove prisms are used as reflective prism inverting the image. Dove prism is shaped from a truncated right-angle prism. Normally, dove prisms are used in the parallel optical path based on critical angle principle to meet total internal reflection with limited FOV. A beam of light entering one of the sloped faces of the prism undergoes total internal reflection from the inside of the longest (bottom) face and emerges from the opposite sloped face. Images passing through the prism are flipped, and because only one reflection takes place, the image is inverted but not laterally transposed. A beam of light entering the sloped faces undergoes total internal reflection from the bottom surface, and emerges from the opposite sloped face. Also interestingly whtn dove prisms optical are rotated along longitudinal axis, the image rotates at twice the rate of the prism which have applications in fields such as interferometry, astronomy, and pattern recognition. Dove prisms can be also used as right angle prisms with sloped faces HR coated.

Elliptical Mirror is 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 mirrors are 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. Elliptical 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. For more information on our stock elliptical mirrors, to place an order or to find out more about our custom capabilities please contact our technical sales team.

The concave mirror is the reflection imaging, it is not the light through, but the reflection back to the imaging instrument, the light observes the reflection law. A concave mirror is a spherical mirror which has no chromatic aberration because there is no refraction but still has a spherical aberration. If a mirror without spherical aberration is required, a parabolic / ellipsoidal / hyperboloid mirror can be selected.
