Dove Prism

Dove prisms are specialized precision optical components designed as image rotators. As light transmits through a Dove prism, the image is inverted by 180°—a key trait for optical orientation adjustment.

Metal-coated Dove prisms are capable of replacing retroreflectors in specific optical setups, offering a compact alternative with reliable performance. Structurally, Dove prisms can be regarded as right-angle prisms with excess right-angle sections removed—this optimized design not only reduces the prism’s weight but also minimizes internal reflection of stray light, enhancing optical clarity.

Dove prisms boast broad applicability across various optical devices, including cameras, projectors, fingerprint scanners, optical accumulators, rangefinders, viewfinders, and mechanical sights. These devices often rely on Dove prisms to redirect light paths, adjust image orientation, or achieve other specialized optical effects, leveraging the prism’s versatile optical properties.

AOS Optics can provide metal-coated Dove prisms tailored to your requirements, paired with optional anti-reflection coatings to further optimize light transmittance and reduce stray light interference, perfectly matching the performance needs of your optical systems.
