Optical lenses are transparent components that refract and focus light. Made from glass or plastic, they are essential in cameras, telescopes, microscopes, and eyewear for correcting vision, magnifying images, and concentrating light beams.

About Us

As a China Optical Glass Supplier, we provide custom fabrication and processing services for various types of optical glass. Our company has years of accumulated technical experience. There will be a strict assessment system for the selection of materials. We currently offer a variety of materials such as Sappire Glass, Quartz Glass (JGS1/JGS2/JGS3), K9 Glass,Calcium Fluoride Glass,etc.
Processing techniques involved: cutting (square/circular/irregular), drilling (square/circular/irregular), grinding (straight/circular/oblique), welding (powder fusion technology and manual docking), slotting (customized according to the drawing), coating(for most of glass), controlling the shape and dimensional tolerances (can be processed to 0.02mm~0.1mm)

Optical glass involves different processing techniques

“Cutting”

Optical glass plates/discs/irregular sheets are one of the components of various instruments and equipment. Its formation can be achieved with extremely precise dimensions through CNC cutting. The tolerance of conventional glass plate size can reach within 0.05mm.

“Drilling”

For glass with higher hardness (such as sapphire glass, quartz glass), the difficulty of drilling holes is relatively high. Therefore, tungsten steel alloy drill bits with higher hardness will be chosen in CNC machining. Processing shapes include square holes, round holes, and irregular holes.

“Chamfering”

The processing of chamfering or edge grinding is to passivate the edges of finished glass sheets or glass components. Prevent cutting the skin during use. CNC can control the width of chamfer dimensions. Processing shapes include straight/rounded/beveled edges.

“Slotting”

For optical glass parts, slotting is a necessary processing procedure. This can make it more adaptable to various optical devices. Our company’s processing of fine grooves can reach a width range of up to 1mm.

“Polishing”

Polishing is the most critical factor determining the practical use of optical glass. The higher hardness, the greater difficulty to polish (such as quartz and sapphire plates/discs). Our standard finish for processing is 60/40. A higher level of smoothness can reach 20/10.

“Welding”

For optical glass instruments that are made of the same material as a integrity, welding will be used, such as quartz glass components and glass labware. The general welding processes include powder fusion welding and manual welding.

“Centering & Edging”

For lenses, it is necessary to grind their outer circle to the precise final diameter and ensure that the optical axis of the lens coincides with its mechanical axis (centering).

“Coating”

Optical coating processing involves depositing thin films on substrates using techniques like evaporation or sputtering. This enhances performance with AR, HR, filters, or protective layers for precision optics in lasers, imaging, and industrial systems.

“Metrology”

Involves: surface accuracy, surface roughness, curvature radius, center thickness/outer diameter and defect issues (surface quality).
