Sapphire Prism

The Sapphire Prism produced by UItraopto Precision Optics Co. Ltd.. is used for rotating, reversing or retroreflective images, UItraopto depending on the rotation Angle of the prism and the light entering the surface of the prism.  

Optoelectronics can produce custom sapphire prisms of various material, size, Angle accuracy, surface shape accuracy, coating and other specifications according to customer requirements.

High transparency and wide spectral transmittance: 

Sapphire prisms have a wide range of transmittance, from ultraviolet to infrared bands (0.17-5.5μm) with good transmission performance, which can reduce the energy loss of light during conduction and ensure efficient light transmission.

Refractive index stability: 

The refractive index of sapphire prisms is stable and does not change significantly due to variations in environmental factors such as temperature and humidity, ensuring the stability of the optical system.

Low birefringence: 

Light is less likely to polarize and disperse as it passes through a sapphire prism, which helps maintain the stability and accuracy of the light.

Ultraopto’s Sapphire Prism is a high-performance optical component crafted from high-purity single crystal alumina (Al₂O₃), engineered to deliver exceptional optical and physical performance in the most demanding industrial, scientific and aerospace applications. Boasting a Mohs hardness of 9, second only to diamond, our Sapphire Prisms exhibit unparalleled scratch and wear resistance, maintaining pristine optical surface quality even after long-term use and rigorous cleaning, eliminating performance degradation caused by surface damage in high-precision optical systems. This premium optical prism features an ultra-broad spectral transmittance range, with excellent light transmission from the deep ultraviolet (0.15μm) to the mid-wave infrared (5.5μm) band, enabling reliable light conduction and beam control across diverse wavelength requirements for laser technology, spectral analysis and optical detection systems. 

Manufactured with ultra-precise grinding and polishing processes, our Sapphire Prisms achieve strict dimensional tolerance control and superior surface flatness, with low birefringence that minimizes light polarization and dispersion during transmission, ensuring high-fidelity light signal delivery and accurate optical performance for precision optical instrumentation. Beyond its optical advantages, this prism offers extraordinary thermal and chemical stability, with a melting point of 2050°C that allows stable operation in extreme high-temperature environments, and strong corrosion resistance to common acids, alkalis and chemical solvents, making it suitable for harsh industrial processing and aerospace working conditions. We implement multi-stage quality inspection throughout the production process, from high-purity sapphire material selection to precision processing and finished product testing, ensuring each Sapphire Prism meets international high-end optical manufacturing standards and delivers consistent, reliable performance in critical applications. 

Ultraopto’s Sapphire Prisms are widely applied in a wide range of professional fields that demand high durability and stable optical performance, including laser systems where they withstand high-power laser irradiation with efficient heat dissipation, semiconductor manufacturing as high-precision substrate materials for GaN growth, and aerospace & defense systems that require reliable optical components in extreme temperature and corrosive environments. They are also essential in high-precision optical instruments such as spectrometers and spectrophotometers for accurate spectral analysis, medical devices for clinical detection and laser therapy, and scientific research experiments for optical measurement and material analysis under complex environmental conditions.
