Image quality in any projection system depends on the optical lens, which determines brightness, focus, and overall image stability. Union-Optech develops projection lenses with a compact design, strong brightness, and precise images for different environments, from homes and classrooms to offices and commercial displays. These projection lenses are easy to install and deliver clear, vivid visuals that create a flexible and immersive viewing experience.

• China’s first ultra-short throw ratio 4K ultra-high-definition projection lens, engineered for ultimate performance.
• Global leader in ultra-short throw projector lens shipment
• Widely used in laser TVs, smart homes, business and education systems, and engineering projects.

• Laser Light Source These projection lenses are designed for laser systems that reach up to 25,000 CVIA lumens and can last around 30,000 hours, roughly 20 years if used four hours a day. And their built-in light compensation system keeps the brightness stable over time, so the image stays clear even after years of use.
• Ultra-Short Throw Lenses Our self-developed Tr0.18 ultra-short throw lens projects 100-inch images from just 0.2 m away. Using aspherical molded glass lenses, it keeps edge distortion below 1%, providing a clear and stable picture even at very short distances.
• Thermal Control To handle heat and noise during operation, the lenses work with a hidden dual-fan cooling system that keeps the surface temperature below 40 °C and reduces noise to 28 dB, similar to a quiet library, so the projection stays stable and the environment remains comfortable.

Nowadays, success in the AR (Augmented Reality) and VR (Virtual Reality) device market depends more on user experience than on technology itself. Modern users want a convenient and enjoyable device, rather than just a collection of visual displays and interaction features. Key factors in choosing a device are comfort during wearing, smooth performance, and reliability. AR/VR devices should be ergonomic and comfortable to wear for long periods, responsive to dynamic environments, and able to operate under different conditions. Union-optech has addressed these requirements with its specialised solution, which makes AR/VR devices smaller, improves visual clarity and image quality, and ensures smooth performance in all conditions.

• Pancake Ultra-Slim Design Pancake design refers to a folded optical system without bulky components. It reduces thickness and overall volume of the device by more than 30%. The optical engine is reduced to 15mm (from the original 30mm), resulting in a smaller and more comfortable device for continuous use.
• Glass-Plastic Hybrid Optics This solution combines glass and plastic lenses with molded aspherical lenses. This type of lens ensures image clarity from the centre to the edges, expanding the field of view to over 90˚. The result is balanced precision, reduced eye strain, and true-to-life visuals.
• Brighter and Smaller AR Optical EngineLeveraging integrated innovations, the design delivers a lightweight, high-brightness AR light engine with a volume of 0.15 cc, a weight of 0.3 g, and a 30° FOV. Its green-bean–sized form factor is 50% smaller and lighter than traditional light engines. It outputs 8 lm while consuming only 60 mW in notification scenarios. With its tiny size, low power, and high brightness, Union-Optech sets a new benchmark for AR light engines and an ideal choice for ultra-light AR glasses.
