Import Dove Prism — Buy in wholesale FOB from Supplier in China

The Dove Prism offered by Photonchina Co., Ltd. is a truncated right‑angle optical prism designed to invert an image and reverse its handedness. Light entering one sloped face undergoes total internal reflection on the longest bottom face and exits the opposite sloped face, producing a rotated output proportional to the prism’s rotation. The top surface is ground, while the longest length retains an unbeveled sharp edge for precise beam handling. Photonchina supplies the prisms in three surface‑finish options: uncoated, anti‑reflection coated diagonal faces, or aluminized diagonal faces with a protective aluminum layer and black Krylon paint.

While the listing does not specify the glass type, most Dove Prisms are fabricated from BK7 crown glass, which offers a refractive index of approximately 1.517 at 589 nm; this is indicated as a typical material for the product class. Standard industry tolerances for the internal angle are ±0.05°, and surface flatness is commonly λ/10, which ensures minimal wavefront distortion. The anti‑reflection coating typically reduces surface reflectance to below 0.5 % across the visible spectrum, and the aluminized version provides durable retro‑reflection for laser applications. For best performance the prism should be used with collimated light to avoid beam divergence.

Dove Prisms are employed in optical instrumentation such as interferometers, laser beam steering systems, and image‑rotation modules for scientific and industrial imaging. Manufacturers of precision optical equipment, research laboratories, and laser system integrators are the primary buyers. Photonchina states that the prisms are produced for worldwide export and can be shipped in protective foam‑lined cartons; however, exact minimum order quantities, lead times and Incoterms must be confirmed directly with the supplier.

Photonchina Co., Ltd. is headquartered at 15, Binzhou Road, Jinshan Industrial Park, Fuzhou, Fujian 350008, China. The company is listed with a harbor trust tier on the platform and currently shows a response rate of 0 % with no recorded response time, indicating that inquiries may require follow‑up. Its facility is situated within the Jinshan Industrial Park, a zone known for precision optics manufacturing.

The supplier emphasises a focus on Dove Prism production spanning more than two decades, targeting customers in image display and fiber‑communication sectors worldwide. No specific certifications, capacity figures or client references are disclosed in the listing, so buyers should request supporting documentation if required.
