Laser Cutting of Glass — Technical Guides for Optical Engineers

33 application notes on laser-cutting glass and fused silica parts: edge quality, dimensional tolerances, thermal effects, cost drivers, inspection and failure modes.

Laser cutting shapes optical glass, fused silica and other brittle substrates without mechanical contact: a focused beam scores and separates the material, so the outline is no longer limited by what a wheel or a CNC mill can reach. The result is defined as much by the thermal process as by the machine — edge chipping, micro-cracks, kerf geometry and heat-affected behaviour all follow from how the cut is driven. This page collects every Jingyu Optics guide on the subject — 33 articles covering specification, selection, cost, quality, comparison and troubleshooting — so that an engineer can find the relevant note without searching.

How a laser-cut glass part is specified

The parameters below come up in every one of the guides, and each of them changes what the cutting process has to achieve. They are the fastest way to describe a part in an enquiry.

  • Material and thickness: optical glass, fused silica, borosilicate or crystal substrate, and the thickness the cutting process must separate cleanly.
  • Part outline and features: outside profile, corner radii, slots and hole diameters — the geometry that decides whether the part is cut, drilled or both.
  • Edge quality: chipping, micro-cracks, kerf width and edge taper, which decide how much finishing the edge needs before coating or assembly.
  • Dimensional tolerances: outside dimensions, hole positions and flatness after cutting, within the budget the mount allows.
  • Thermal effects: how the process limits heat input into thin substrates, and what that means for strength and downstream handling.
  • Downstream processing: whether the part is cold-processed, ground, polished or coated after cutting, and how the cut edge interacts with each step.
  • Inspection: edge and surface inspection, dimensional verification and documentation for production parts.

Manufacturing and supply

Jingyu Optics Co., Ltd. is an optical component manufacturer in Zhuji, Zhejiang, China. The company supplies optical glass and fused silica substrates, custom multi-layer thin-film coatings and precision cold-fabricated glass components to OEM/ODM customers. The catalogue covers 426 products across three groups: coatings (255), materials (135) and fabrication (36).

Over 3,000 m² own plant, Class 1000 cleanroom, nearly 20 coating chambers, laser cutting machines, ultrasonic cleaning lines and spectrometric inspection systems; one-stop chain of substrate cold processing → multi-layer coating → ultrasonic cleaning → 100% final inspection.

Ordering: Sample lead time: 1–2 days for coated stock optics, and about 3 days for custom-coated parts, subject to coating design complexity. In-stock products ship within 1–2 days. Custom fabrication orders take approximately 5–7 days. Our team starts processing right after receiving your order. We can provide quotations and arrange expedited production if you have a required lead time. MOQ depends on the product. We are flexible: small-batch and trial orders are welcome for new projects, and we scale up to mass production once the design is validated. T/T bank transfer and major international payment methods. Shipping terms include EXW, FOB, CIF; by sea, air or express courier as you prefer. An engineer (not a robot) replies within 24 hours with a quotation and lead time. Enquiries go to the contact form or xiao@gobofactory.com.

Markets served: Europe, North America, Russia & CIS, Australia and New Zealand, South America, the Middle East, and China (mainland, Hong Kong, Macau and Taiwan).
