Substrate & geometry
Define the viewing area, outside dimensions, thickness, edge finish, corner radii, holes and mounting clearances. Glass type and any strengthening process must suit the assembly and service environment.
Products / LCD Enhancements / AR Cover Glass
A clearer view.
A cover built for your display.
Reduce distracting surface reflections while protecting the display. Select anti-reflection cover glass, the mechanical design and the optical stack together—from cut-to-size glass to a custom front window.
Specify the window, not just the coating.
Surface & appearance
Choose single- or double-sided AR, the visible wavelength band and viewing angles. Review residual reflection color, haze, cleaning resistance and any black-mask printing or surface finish.
Integration & use
Account for touch sensing, heater and shielding layers, adhesives, seals and mounting stress. Prototype the complete stack under the lighting and viewing conditions your users will encounter.
Make every optical interface count.
AR reduces surface reflection.
A thin-film AR stack uses optical interference to reduce reflected light over a designed spectral band. It is different from anti-glare texture, which spreads reflections and can change haze and image sharpness.
An untreated air-to-glass surface with refractive index near 1.5 reflects approximately 4% at normal incidence. That is a single-interface estimate, not a complete display reflection specification.
Explore AR technology and reference curves →Bonding changes the inner interface.
Optical bonding replaces the air gap between rigid surfaces with an optical material. Choose the inner coating for the actual bonding medium; a coating optimized for air may behave differently when bonded.
Lamination attaches a flexible layer, such as an AR film on PET. Glass coatings and flexible films provide different mechanical and processing options.
Review optical bonding and lamination →Start with an existing glass family.
Explore custom covers, cut-to-size material and coated sheets. Final dimensions, coating orientation and processing are confirmed during review.
Custom AR Cover Glass
Define the front window around your display, enclosure and optical requirements.
1.1 mm AR glass, cut to size
Single-sided AR soda-lime glass for a drawing-defined cover or development build.
1.1 mm HEA glass
Single-side coated glass; review the surface orientation and integration requirements.
Spectral filter glass
Transmit the useful light. Attenuate the infrared.
SCHOTT BG38, BG40, BG39 and S8612 absorb near-infrared light. Compare the red-edge transmission, full blocking band and thermal load before choosing a grade or thickness.

Absorptive glass attenuates red light as well as infrared. AR reduces interface reflection; it does not replace IR filtering. Match the material to the LED/LCD spectrum, temperature, bonding and viewing requirements.

Internal transmission excludes surface reflections and BBAR / AR coating effects. The curves show published material reference data; finished-component performance depends on thickness, coatings and the complete optical stack. Below-limit values are plotted at their reported upper bounds.
Bring the display and the environment.
What to include
- Display drawing, active area and cover dimensions.
- Lighting, viewing angles and acceptable reflection, transmission and haze.
- Touch, heater, shielding, printing and bonding requirements.
- Cleaning, temperature, humidity and mechanical requirements.
- Prototype quantity, production volume and target schedule.
Build a coordinated front stack.
We can help define the glass and coating route, evaluate samples and plan integration. Selection and qualification apply to the complete assembly.
