Circle Sight Electronic 6H Ultra Clear AR Tempered Glass Anti‑Reflection Cover Glass
The circle ar tempered glass widely used in downlight, CCTV, etc. and the process is simple but quality is vary under different methods.
The process method depends on application, lighting normally use laser, shapping machine, and higher standard(edge treatment, tolerance, surface quality) we will use CNC to meet.
If there any other question, please recommend to contact us!
What’s AR Tempered Glass And What Role Weiman Playing?
The circle ar tempered glass usually use soda lime float glass to be raw material for process, and the ultra clear(super white) is more widely use due to higher transmittance(91% above) and white(not green) from side view).
With AR(Anti reflection) coating for ultra clear glass, sing side increase 3-4~% transmittance, both sides up to 99% highest.
Different shapes and sizes of tempered glass can customize base on your requirements(drawings). After tempering, the circle glass has strong mechanical strength and safe to human.
When break, the glass will become into blunt glass fragments(small particles without sharp edge) to guarantee the safety.
In Weiman, we offer full in house production including cutting, CNC processing, tempering(chemical & thermal), silkscreen printing, coatings(AR, AG, AF) and bonding(3M tape, OCA tape).
AR Tempered Glass Substrates Reference
– Soda lime glass: widely available, cheaper and the working temperature up to 280 °C.
– Borosilicate glass: particularly suitable for aggressive environments (acids, alkalis, water vapor), working temperature up to 350 °C.
– Quartz glass: working temperature up to 1100 °C.
AR Tempered Glass Surface treatments
Sandblasting: From industry, the sand option from #100 to #320(from rough to fine) depends on customer’s lighting effect requirement.
Printing: Low temperature ink(Stronger light block capability, can scratch out) and high temperature ink(weaker light block capability, can’t be scratched).
Coating: AR(Anti reflection), AG(Anti glare) and AF(Anti fingerprint).
Bonding: 3M tape + OCA tape available to laminate base on design.
Customization size
Diameter(width/length) 10-420mm.
Thickness: 2-30mm (can be tempering) but 30-85mm (can not be tempering).
AR Tempered Glass Features
-The tempered glass can offer 4- 5 times stronger than ordinary anneal glass.
-In the event of breakage, it fractures safely into relatively small pieces with harmless dull edges.
-It can withstand a wide range of rapid temperature change.
AR Tempered Glass Process methods
-CNC, it refers to high quality standard:
1.Precision tolerance ±0.05.
2.High surface quality: reduce defectives like scratch, dots, etc.
3.Even shape and edge(chamfer can be customized), the production cost relatively higher.
-Laser, the convenience allow the production speed much faster & cost lower.
Better tolerance ±0.02. But weaker chamfer compare to CNC(For lighting application, because it normally use hand chamfer instead of CNC to reduce cost).
AR coating: Plating on single side or double sides, the AF coating usually applied if the AR coating expose in outside.
Package
-PET film apply in double sides for high quality standard.
-Dustfree paper apply for lower cost option.
FAQ
Q1: What base materials do you use for AR tempered glass?
A1: We supply soda lime, borosilicate and quartz glass. Ultra clear soda lime glass is widely used with over 91% transmittance and no green edge tint. Each material handles different maximum working temperatures from 280 °C up to 1100 °C.
A2: Single side AR coating improves transmittance by 3-4%. Double side AR coating can hit a maximum of 99% base on ultra clear glass for superior optical performance.
A3: Custom size: 10-420 mm in diameter/length. Temperable thickness: 2-30 mm. Full in house work includes CNC/laser cutting, tempering, silkscreen, AR/AG/AF coating and 3M/OCA tape bonding per drawings.
A4: It is 4-5 times stronger than regular annealed glass. When broken, it forms blunt small fragments without sharp edges.
A5: Treatments: #100‑#320 sandblasting.
Weiman Tech can offer different customization services for tempered glass to satisfy with customers’ specific demand.
