Customized pentagonal prisms, available in different sizes as per your requirements. Minimum order quantity: One piece. Bulk orders enjoy discounts.
The pentagonal prism produced by UItraopto Precision Optics Co. Ltd.has a 90° light deflection characteristic and can generate right-handed images. The reflective surface is coated with an AL film. Even a slight movement of the prism does not affect the precise right Angle of light reflection, so the pentaprism is an ideal tool for generating right-angle deflection in optical systems. Custom pentagonal prisms of all sizes are accepted. UItraopto Precision Optics Co. Ltd. can stably provide such products with high beam offset and high resolution through precise control of polishing, coating and bonding processes.

Ultraopto’s Pentagonal Prism is a high-precision optical component expertly engineered for stable 90° light beam deflection and upright image transmission, serving as a core part in surveying and mapping instruments, laser scanning systems and projection display equipment. Characterized by its unique five-sided structural design, our Pentagonal Prism features the outstanding advantage of angle-independent 90° light deflection – the incident light beam is stably deflected by 90° regardless of changes in the optical axis and incident light angle, and the image is kept upright without inversion or distortion, which is crucial for optical systems that require high-precision and stable light path control, and eliminates the need for frequent recalibration caused by light angle changes, significantly improving the work efficiency of optical instruments.
Crafted from premium BK7 grade A optical glass (H-K9L), our Pentagonal Prism is manufactured with ultra-precise grinding and polishing processes, implementing strict micron-level dimensional tolerance control (±0.2mm) and angular tolerance control (90° deviation tolerance as low as <1 arc second for high-precision series), with superior surface flatness of λ/2 @632.8nm and a surface quality rating of 60-40 scratch and dig, ensuring low optical loss and high-fidelity light and image transmission for precision optical systems.
Our Pentagonal Prism is optimized with professional optical coating technology, with multi-layer anti-reflection coatings on the incident and emergent surfaces, achieving an average reflectivity of less than 0.5% in the visible light band (630~680nm), and enhanced aluminum coatings with black paint on the reflection surfaces, with an average reflectivity of over 85% @630~680nm, effectively reducing surface reflection loss and improving light transmittance and image clarity. The product features a compact and robust structural design with customizable chamfer sizes (<0.5mm×45°) and an effective aperture of over 90%, ensuring seamless integration with various optical systems and avoiding light path offset and coupling errors caused by dimensional deviations.
With excellent mechanical strength and environmental adaptability, our Pentagonal Prism is resistant to temperature changes, mechanical vibration and industrial field wear, ensuring long-term stable operation in complex working environments such as outdoor surveying and mapping, industrial laser scanning and indoor projection display. We also offer customizable coating processes for specific spectral ranges including UV and infrared, tailoring the product to the unique wavelength and application requirements of your optical system, and further enhancing its optical performance and adaptability.
Ultraopto’s high-precision Pentagonal Prisms are widely applied in a broad range of professional optical fields that demand stable 90° light deflection and upright imaging, including surveying and mapping where they serve as the core component of theodolites, total stations and other surveying instruments, providing stable light path control for high-precision geographic mapping and engineering measurement.
They are also essential in laser scanning and alignment systems, ensuring stable 90° laser beam deflection for precise laser scanning of industrial products and laser alignment of precision equipment, and in projection display systems for light path adjustment and upright image projection, delivering clear and stable display effects for large-screen projection and professional optical projection. In industrial machine vision systems, our Pentagonal Prisms are used for 3D modeling and stereoscopic vision creation, distributing laser beams and correcting optical paths to generate high-precision depth images for accurate dimensional measurement and surface defect detection of industrial products. Additionally, they are applied in visual aiming systems, aerospace optical sensors and scientific research optical experiments, providing stable and reliable 90° light deflection and upright image transmission, and meeting the diverse high-precision optical path design requirements of surveying, laser technology, display and scientific research fields.
