Rhombic Prism

Rhombic Prisms, also known as oblique prisms or Fresnel prisms, are often used in applications where the direction of the laser beam remains unchanged. The rhombic prisms produced by UItraopto Precision Optics Co. Ltd. are frequently employed for beam deflection. In imaging applications, the rhombic prism can shift the optical axis while keeping the image from flipping. The lateral offset is equal to the length of the prism (calibrated by D). UItraopto Optoelectronics can produce rhombic prisms with high precision Angle tolerances, ensuring that the parallelism error between the output beam and the input beam is within 30 UItraopto Precision Optics Co. Ltd. accepts custom rhombic prisms of all specifications.

By precisely controlling the polishing, coating and bonding processes, UItraopto  Optoelectronics can stably provide this type of product and accept custom prisms of various specifications.

Ultraopto’s Rhombic Prism is a high-precision optical component engineered for non-deviating, non-rotating beam displacement, serving as a core part in high-resolution optical imaging systems, laser alignment setups, precision optical instrumentation and professional optical equipment across aerospace, biomedical and industrial fields. Featuring a symmetrical rhombic structural design with four precisely polished optical surfaces, our Rhombic Prisms shift the incident light path parallel to itself without altering the beam’s direction or causing image rotation, which is critical for optical systems where light path adjustment is required without distorting the original optical signal. 

We manufacture our Rhombic Prisms with advanced ultra-precise grinding and polishing technologies, implementing strict micron-level tolerance control over all critical optical parameters including side length accuracy, angular parallelism, surface flatness and optical transmittance. Every Rhombic 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 performance in ultraviolet (UV), visible and infrared (IR) spectral ranges, high surface hardness and stable mechanical properties, able to withstand complex industrial working conditions and high-precision scientific research requirements. Our strict multi-stage production quality control system, from raw material screening to finished product performance testing, ensures that each Rhombic Prism meets international high-end optical manufacturing standards, delivering consistent and reliable beam displacement performance with low optical loss in the stringent working environments of optical imaging, laser processing and scientific research laboratories. 

Our Rhombic Prisms boast outstanding core optical advantages, with ultra-precise parallel beam displacement that ensures the incident and emergent light paths are perfectly parallel, eliminating beam deviation and image distortion to maintain high optical signal fidelity, which is essential for high-precision optical imaging and laser alignment applications. The optimized symmetrical structural design and advanced surface processing technology realize high light transmittance and minimal optical loss, minimizing reflection and scattering loss on the prism’s optical surfaces through precision polishing, maximizing the utilization of light energy and reducing signal attenuation in the beam transmission process. The high dimensional precision and flawless surface quality of the prism ensure seamless integration with various optical systems and laser equipment, avoiding optical path offset, coupling errors and signal distortion caused by dimensional deviations or surface defects, and enhancing the stability and reliability of the entire optical setup during long-term operation. We also provide customized wavelength-specific anti-reflection (AR) coating services for Rhombic Prisms, further reducing surface reflection loss and improving optical transmittance for specific spectral ranges, making the product more suitable for the unique wavelength and application scenarios of customers' optical systems. In addition, the prism features a robust and compact structural design, with excellent resistance to temperature changes, mechanical vibration and industrial field wear, ensuring long-term stable and reliable operation in complex industrial working environments, harsh outdoor optical application scenarios and high-precision laboratory conditions.
