Micro Prism

Micro prisms, produced by UItraopto Precision Optics Co. Ltd, are micro prism products specifically designed for laser light sources and imaging applications. They offer coated and uncoated versions. These 45°-90°-45° right-angle prisms have a size range from 0.2 millimeters to 5.0 millimeters (A=B=C)  equilateral format), and are manufactured using high-precision grinding technology to ensure the accuracy of angles and surfaces.

Customized anti-reflection/reflective coatings can optimize the performance for specific wavelengths, meeting the strict requirements of micro-optical systems for compactness and reliability. They are ideal choices for optical fibers, laser radars, and precision instruments, performing well in high-precision devices with limited space.

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 orders for prisms of various specifications.

Ultraopto’s Micro Prism is an ultra-compact high-precision optical component expertly engineered for precise light beam deviation, redirection and control, serving as a core part in miniaturized optical systems, fiber optic communication devices and high-precision measurement setups. As a specialized miniaturized optical prism, our Micro Prism is crafted from premium optical materials including BK7 grade A optical glass and Corning Fused Silica 7980, with ultra-precise grinding and polishing processes ensuring strict angular and dimensional tolerance control, delivering a reflectivity of over 95% per face at 1550nm wavelength and minimizing optical signal loss for high-fidelity light transmission. Designed with an ultra-compact structure, our Micro Prism occupies minimal space inside optical assemblies while achieving high-precision light path adjustment, enabling the miniaturization and high efficiency of optical switches, circulators and interleavers in fiber optic communication systems, and perfectly matching the compact design requirements of modern micro-optical devices.

Our Micro Prism boasts exceptional optical performance with precise light deviation accuracy, where the carefully engineered prism faces and angles ensure light beams deviate at the intended angle with high consistency, and the light reaches the target position more reliably than traditional mirror or multi-component systems that require perfect alignment. The product supports stable light control at core communication wavelengths of 1310nm, 1550nm and 1590nm, with a surface quality rating of 40-20 scratch and dig, superior flatness of λ/2 @632.8nm and a clear aperture of over 90%, further reducing light scattering and reflection loss and ensuring stable optical performance in long-term use. We also offer customizable bevel designs from 0.1mm to 0.2mm and wavelength-specific anti-reflection coatings, tailoring the product to the specific application requirements of different optical systems and enhancing light transmittance for UV, visible and infrared spectral ranges.

Ultraopto’s high-precision Micro Prisms are widely applied in a wide range of professional optical fields that demand compact size and precise light control, including fiber optic communication where they realize high-precision light beam switching and redirection for stable signal transmission, and laser interferometry for measuring surface topography with sub-nanometer accuracy and enhancing the efficiency of light collection and detection in spectroscopy. They are also essential components in aerospace optical navigation systems and aircraft manufacturing precision alignment systems, providing reliable light path control for high-precision measurement in extreme environments, and in the medical field for precise eye measurements in vision correction surgery and improved visualization in minimally invasive endoscopy procedures. In the manufacturing sector, our Micro Prisms are used for quality control and inspection in semiconductor production and accurate metrology in automotive component measurement, as well as in defense and security target acquisition and tracking systems for precise optical sensing and detection.

As a leading manufacturer of precision optical prisms, Ultraopto offers fully customized Micro Prism solutions to meet your unique micro-optical application requirements. Our professional R&D and engineering team can provide personalized customization of prism types including micro penta prisms and micro right-angle prisms, with strict control over 90° deviation tolerance (as low as <2 arc seconds for precision series), dimensional tolerance (±0.0,-0.1mm) and flatness to match the most stringent optical system specifications. We also support custom material selection and coating processes, tailoring the product to your specific wavelength and environmental requirements, and ensuring high reflectivity and low signal loss for your optical devices.
