Glass & Optical Polymers

Optical Materials

Optical material selection affects transmission, refraction, impact resistance, temperature capability, chemical compatibility, weight, surface durability, and manufacturing method.

No single optical material is best for every industrial application. A machine-light window, precision lens, molded diffuser, inspection filter, and light guide may each place different demands on the material.

Glass Components

Rigid Transparent Materials

Glass materials can provide useful optical, thermal, chemical, and dimensional properties for windows, lenses, covers, and other technical components.

Glass fabricators can cut, shape, finish, drill, polish, or otherwise process glass according to the component geometry and manufacturing requirements.

Borosilicate

Borosilicate Glass

Borosilicate glass is one technical glass family used in industrial applications where its particular material properties are appropriate.

Material suitability should still be evaluated against the actual wavelength, temperature, pressure, impact, coating, cleaning, and mounting requirements.

Precision transparent optical components

Optical Plastics

Transparent Polymer Materials

Optical polymers can support lightweight parts, molded geometry, integral mounting features, diffusing textures, complex shapes, and economical repeat production.

The broader category of plastic materials includes many polymers with very different optical, mechanical, thermal, and chemical properties.

Polycarbonate

Impact-Resistant Transparent Components

Polycarbonate can be considered for protective covers, windows, formed components, and molded optical hardware where its combination of properties fits the application.

Polycarbonate manufacturers supply material forms used throughout industrial products.

Acrylic

Fabricated and Guided-Light Components

Acrylic can be fabricated into transparent panels, diffusers, windows, and light-guide structures when its optical and mechanical characteristics suit the assembly.

Acrylic fabrication can include cutting, machining, shaping, joining, and other processes used to create finished parts.

Manufacturing

Molding Optical Polymers

Complex lens, diffuser, light-guide, and optical housing geometries can be produced through plastic injection molding when the selected polymer, optical requirements, tooling strategy, and production quantity support that process.
