High-Precision Optical Components & Semiconductor-Grade Photomask Substrates (Photo Reticle) Manufacturing Solutions
As a global leading precision optical components manufacturer (Optical Components Manufacturer), we specialize in delivering full-chain, one-stop solutions—from optical blank processing (Optical Blank Processing) to semiconductor-grade photomask substrates (Photo Reticle Substrates)—for the semiconductor, display panel, professional photography, and high-end scientific research industries. Leveraging our proprietary large-scale double-sided lapping and polishing technology (Double-sided Lapping & Polishing), we can reliably process everything from micro-scale optical components to massive 50-inch (1250mm) ultra-large precision substrates, achieving nano-level surface flatness and breaking import dependency. We provide cost-effective, high-performance import substitution optical products to customers worldwide.
Why Choose Our Precision Optical Processing Services?
In an era where semiconductor lithography processes are becoming increasingly stringent, display panel resolutions continue to rise, and photography filters demand extreme light transmittance, selecting a supplier that truly masters core processing technology is critical. We are not just a manufacturer—we are your trusted technical partner:
Fully vertically integrated supply chain: From raw material melting, blank cutting, double-sided grinding, precision polishing, ultrasonic cleaning, to final inspection, every step is controlled in-house with our self-developed equipment. This means shorter lead times, more stable quality, and no middlemen.
Nano-level processing precision: Our internationally advanced 60B large-scale double-sided polishing machines deliver sub-nanometer surface roughness (Ra < 0.1nm) and ultra-flat surfaces that exceed industry standards.
Ultra-large production capacity: Our 50-inch large-format production line achieves a monthly output exceeding 500,000 pieces, supporting everything from small-batch prototyping to million-piece OEM/ODM mass production to meet global supply chain demands.
Proven import substitution capability: We fully replace high-end imported photomask substrates, camera filter blanks, and large-size optical windows, helping customers reduce costs by 30%–50% while matching or surpassing international brand performance.
One-stop custom service: From design to mass production, we provide complete technical support, including fixture-based batch production, special material matching, and strict cleanliness control.

We’ve been partnering with you for 10 years now, and have used quite a number of your encoder discs over that time. I have to say, the latest batches are the best-looking and most precise ones I’ve seen in all these years on our test equipment. Our theodolite and level instrument motors are now fully back in spec, with rock-solid performance. It’s great to see the flutter tests and time base error tests all returning to normal — the results are excellent. Thank you and your team for the consistent support and quality over the past decade!
