Wedge Prism

The Wedge Prisms produced by UItraopto Precision Optics Co. Ltd can be used to separately deflect the laser beam to a certain angle, or to combine two wedge prisms together for beam deflection applications. 

A single prism can shift the incident beam by a certain angle. If measured in diopters, it is equivalent to a diopter, which is approximately 1 centimeter of deflection at a distance of 1 meter. UItraopto Optoelectronic offers customized wedge prisms in various specifications.


UItraopto Precision Optics Co. Ltd can consistently supply this type of product through precise control of polishing, coating and bonding processes. It also accepts customized prisms of various specifications.

Ultraopto’s Wedge Prism is a high-precision optical component engineered for precise beam deflection and fine optical path adjustment, serving as a core part in laser alignment systems, industrial optical equipment, precision optical instrumentation and various professional laser setups. Featuring a specialized single or double wedge structural design, our Wedge Prisms can realize accurate, adjustable beam deflection angles by rotating a single prism or combining two matched wedge prisms, enabling micro-adjustment of the light path without changing the overall layout of the optical system, which greatly improves the flexibility and precision of optical path control for industrial production and scientific research applications. We manufacture our Wedge Prisms with advanced ultra-precise grinding and polishing technologies, implementing strict micron-level tolerance control over all critical optical parameters including wedge angle accuracy, surface flatness, parallelism and beam deflection precision. Every Wedge Prism is crafted from premium high-transmittance optical materials including N-BK7, Fused Silica and other high-quality optical substrates, carefully selected for their excellent optical transmittance in ultraviolet (UV), visible and infrared (IR) spectral ranges, high laser damage threshold and stable mechanical properties, able to withstand high-power laser irradiation and complex industrial working conditions, and meet the diverse wavelength and application requirements of professional optical and laser systems. 


Our strict multi-stage production quality control system, from raw material screening to finished product performance testing, ensures that each Wedge Prism meets international high-end optical manufacturing standards, delivering consistent and reliable beam deflection performance and low optical loss transmission in the stringent working environments of aerospace, biomedical detection, industrial laser processing and scientific research laboratories. Our Wedge Prisms boast outstanding core optical advantages, with ultra-precise wedge angle control that ensures accurate and repeatable beam deflection, realizing micro-adjustment of the light path with angular accuracy up to arcsecond level, which is essential for high-precision laser alignment and optical measurement applications. The optimized optical design and advanced surface processing technology realize high light transmittance and low optical loss, minimizing reflection and scattering loss on the prism surface, maximizing the utilization of light energy and reducing signal attenuation in the beam transmission process, effectively improving the overall performance of the optical and laser system. The high dimensional precision and excellent surface quality of the prism ensure seamless integration with various optical systems and laser equipment, avoiding optical path offset, coupling errors and beam distortion caused by dimensional deviations or surface defects, and enhancing the stability and reliability of the entire optical setup. 


We also provide customized wedge angle design and wavelength-specific anti-reflection (AR) coating services for Wedge Prisms, with customizable deflection angles and coating specifications to match the specific application requirements of customers' optical systems, and the durable vacuum-plated coatings further enhance the laser damage threshold and environmental adaptability of the product, making it suitable for long-term use in complex industrial fields. In addition, the prism features a compact and robust structural design, with excellent resistance to temperature changes, mechanical vibration and industrial field wear, ensuring stable and reliable operation in harsh outdoor optical application scenarios and high-precision laboratory environments. Ultraopto’s high-precision Wedge Prisms are widely applied in a full range of professional optical and laser fields that demand precise beam deflection and fine optical path adjustment, including industrial laser alignment and calibration such as precision equipment installation, laser processing path adjustment and optical instrument debugging, realizing accurate beam steering for stable laser operation; optical adjustment systems such as industrial machine vision, biomedical imaging and astronomical observation equipment, providing flexible light path micro-adjustment for clear imaging and precise detection; high-power laser systems such as laser welding, laser cutting and laser marking, withstanding high-power laser irradiation and realizing accurate beam deflection; as well as precision optical instrumentation, aerospace optical sensors, laboratory optical experiment platforms and industrial non-destructive testing equipment in the scientific research, aerospace and industrial sectors.
