Glass Lapping & Polishing

Precision Glass Lapping & Polishing Services

At Tihot Optics (Guangzhou) Co., Ltd., we provide industry-grade precision glass lapping and polishing services to meet the demanding requirements of optical, semiconductor, and high-tech applications. With our advanced processing capabilities, we deliver ultra-flat optical glass surfaces with tight control over flatness, parallelism, and surface roughness, enabling performance and reliability in critical systems.

From glass wafers for MEMS to display optics and biomedical covers, our custom services ensure your components meet the highest standards for glass surface finishing, cleanliness, and dimensional accuracy.

Optical Glass Materials for Precision Polishing

Tihot Optics works with a broad spectrum of technical and optical-grade glass materials. Our lapping and polishing systems are optimized for:

  • Borosilicate Glass: SCHOTT BOROFLOAT® 33, Pyrex® 7740
  • Fused Silica and Quartz
  • Aluminosilicate Glass: Corning® Gorilla®, EAGLE XG®
  • Soda-Lime Glass: B270®, D263T™, AF32®
  • Specialty Optical Glass: including IR or UV-transmitting substrates
  • Glass-Ceramics and Filter Glasses

These materials are commonly used in optical filters, imaging windows, semiconductor wafers, and AR/VR optics.

These capabilities allow us to deliver polished substrates ready for integration into semiconductor glass wafer polishing, AR/VR optics, laser systems, and more.

Applications of Ultra-flat Optical Glass

Our glass lapping and polishing services support a wide range of high-precision markets:

  • Semiconductor Glass Wafer Polishing for MEMS, CMOS/CCD sensors, and wafer-level packaging
  • AR/VR Optical Substrates requiring high transmission and precise alignment
  • Medical and Life Science Optics for diagnostic windows and bio-imaging
  • Photonics and Laser Components that demand ultra-flat optical glass
  • Aerospace and Military Sensors where flatness and durability are critical
  • Microfluidic Devices, where consistent thickness enables flow accuracy

Supporting Researchers with Reliable Glass Polishing for Experimental Applications

Over the years, Tihot Optics has supported hundreds of researchers, laboratory engineers, and academic institutions with customized glass lapping and polishing services tailored specifically for experimental use.

We understand that in research and development, every micron matters — whether you’re testing an optical alignment system, building a prototype microfluidic chip, or developing a wafer-level integration platform. That’s why we offer:

Rapid prototyping with small-volume flexibility

Close tolerance control for flatness, parallelism, and thickness

Material consulting to select the most appropriate glass for your experiment

Cleanroom-compatible polishing and packaging

✔ Support for modifications, iterations, and special request geometries

Our team has hands-on experience working with university labs, scientific research centers, and early-stage tech developers—both in China and globally.

Typical Experimental Use Cases:

  • Optical substrate development for AR/VR or laser systems
  • Bonding-grade wafers for hybrid MEMS or packaging studies
  • High-transparency covers for life science instrumentation
  • Ultra-thin polished glass for microfabrication process testing
  • Sample windows for spectroscopy, photonics, or metrology setups

If you’re unsure what material, finish, or geometry your setup needs — just send us your drawings, specs, or experimental context, and our team will help translate that into feasible, accurate, and cost-effective glass components.

No MOQ required for experimental orders. We believe R&D should never be limited by supply.
