Dove Prisms
Image Inversion and Rotation: Dove Prism is capable of inverting and rotating images, depending on the rotation angle of the prism relative to the incident light beam. This property makes it a versatile tool in optical systems requiring image manipulation.
Retroreflection Capability: It can function as a retroreflector, where incident light is reflected back along the same path, but with a possible image rotation. This feature is useful in applications where precise beam alignment is crucial.
Beam Steering: By rotating the prism, the propagation path of the light beam can be altered, allowing for dynamic beam steering in optical systems.
Stable Performance: The solid construction of the Dove Prism ensures stable performance over time, making it suitable for long-term use in demanding applications.
Compatibility with Various Coatings: Dove Prisms can be coated with various materials to enhance their optical properties, such as anti-reflection coatings or aluminization, depending on the specific application requirements.
Reduced Weight and Internal Reflection: As a truncated right-angle prism, the removal of the pinnacle contributes to reduced weight and minimized internal reflection, improving overall efficiency.
Applications: Astronomy, Interferometry, Optical Communication, Laser Systems, etc.
A Dove prism is a type of reflective prism derived from a truncated right-angle prism. Its primary functions include inverting and rotating images, or it can serve as a retroreflector depending on the prism’s rotation angle relative to the light’s propagation path. The Dove prism can be seen as a right-angle prism with its pinnacle cut, which offers advantages such as reduced weight and minimized internal reflection.

Our Dove prisms are capable components in astronomical and interferometrical applications. However, it is important to note that when used with converging light, refraction at the entrance and exit surfaces may result in significant image astigmatism. Therefore, we recommend using them with collimated light to achieve optimal performance.Choose Kingwin Optics for high-quality, custom Dove prisms tailored to your unique application requirements.
