New Arrival of Microprisms

UltraOpto New Product Launch | Microprism, the Ultra-Precise Light Path Control Core for Miniaturized Optical Systems

UltraOpto newly launches the Microprism, an ultra-precise micron-level optical core component, specially designed for miniaturized and integrated optical systems. It can achieve precise light path deflection, beam splitting and combining, and retroreflection in extremely small sizes ranging from 0.2mm to 2mm. It features high reflection efficiency, ultra-high angle consistency, small volume, and strong adaptability, making it a key basic component for miniature optical devices in consumer electronics, automotive electronics, medical imaging, and other fields.

The regular version of the product selects high-quality N-BK7/H-K9L optical glass. Fused silica can be customized for ultraviolet/high-precision scenarios, and silicon-based substrates are suitable for infrared bands, covering the needs from visible light to communication bands. The micron-level processing precision is strictly controlled, with dimensional tolerances of ±0.01~0.1mm, angle tolerances of high-precision models <5 arcseconds, surface flatness of λ/[email protected], surface roughness of RMS≤1nm, and effective light-transmitting aperture >90%. It can be customized with any deflection angle <60°, with excellent consistency in mass production.

The optical surface supports customized coating systems such as AR anti-reflection, HR high reflection, and beam splitting coatings, and can also adopt total internal reflection without coating design. It adopts wafer-level structured processing, ultra-precision molding/etching core processes, combined with optical contact splicing to achieve precise forming of micron-level microstructures, with an annual production capacity of tens of millions. The products are fully inspected by high-precision equipment such as white light interferometers before leaving the factory, and have passed high-temperature resistance, high and low-temperature cycle tests. The optical performance does not drift under temperature change and vibration environments, and the structure is firm, suitable for long-term stable work.

It is widely used in various scenarios such as smartphone periscopes, AR/VR waveguides, vehicle-mounted lidar/HUD, micro endoscopes, fiber optic communication optical switches, and micro industrial cameras. While greatly reducing the volume of equipment, it ensures high-precision light path control. Mainstream specifications are available in stock. Substrates, coatings, and deflection angles can be customized non-standard. Small-batch sampling is supported, and delivery is stable, providing a highly reliable solution for miniaturized optical applications in emerging fields such as metaverse, autonomous driving, and portable medical care.
