>> FELIX OPTICAL GLASS Features :

These Positive Meniscus Lenses are fabricated from ROHS-compliant BK7 glass (N-BK7) and are avalable uncoated or with one of our three broadband antireflection coatings: -A (350-700 nm),-B (650-1050 nm), or -C (1050-1700 nm). These coatings greatlyreduce the 4% loss per surface incurred when using an uncoated lens. Positive meniscus (convex-concave) lenses are designed to minimize spherical aberration, When used in combination with another lens, a positive meniscus lens will shorten the focal length and increase the numerical aperture (NA) of the system without introducing significant spherical aberration, When used to focus a colimated beam, the convex side of the lens should face thesource to minimze spherical aberration.

CUSTOMER AND FEEDBACK
FELIX GLASS



BERNAT BONNIN CEO Medical Devices.S.A


Our Company Working with FELIX GLASS was an absolute pleasure! The product quality exceeded my expectations, and the customer service team was incredibly responsive. From order to delivery,everything was seamless. l'm already planning my next purchase-highly recommend to anyone looking for Display glass panel and optical lens!

>>FAQ-1：

1: Can the AG and AR process be realized on a cover glass ?

A: AG, AR and AF can be realized on the same cover glass, which is called 3A. It is standard for display cover glass.

Q2: What kind of processes can achieve the “dead front effect” of cover glass?

Answer:

A: ①Printing, suitable for small area printing within 20*20mm.

②Electroplating, suitable for small sizes below 7 inches

③The glass material is gray glass, and the maximum size can be 32 inches.

④Film Adhesion, unlimited size

Q3: What is the stress standard after glass chemical strengthening?

A: Corning Gorilla Glass Stress Value: DOL>40um, CS>650Mpa

Soda Lime Glass Stress Value: DOL>8um, CS>450Mpa

Q4: What is the Dead Front Glass?

A: This question has written a lot of introduction, You can search on the FELIX GLASS website and you will find related videos, introductions, and pictures.

“Dead Fronteffect”(All-in-one-black), that is to say, the display is clearly visible when back-lit, and when non-backlit, the entire display including glass is completely black without a color difference. Dead front glass is widely used in smart homes, smart wearables, financials, medicals, and industrial control, etc.

Q5: Will the glass strength be affected after AG etching?

A: Definitely not. Because the etched glass surface is only about 0.05mm depth, and the chemical strengthening is immersion type, which can fully complete the replacement of ions. We have done too many time tests and the results showed that it didn’t affect the strength of the glass.

Q6: For AF（Anti-Fingerprint） coating, how much is the qualified water contact angle?

A: FELIX GLASS Standard Water Contact Angle is >105°, Abrasion Test: 200g weight，Steel Wool#0000, 2000times(back and forth as 1 time)，Recession Value within 15%

Q7: How to recognize the etched side?

A: The easiest way is to hold the AG glass under a fluorescent light and look at the tube reflected on the glass from the front. If the light is scattered on the glass, it is etched side. If the light is clearly visible, it is a non-ag side. This is the most direct way to distinguish from the visual effect.

Q8: How many days to deliver custom cover glass ?

A: Gorilla glass 3, gorilla glass 4, gorilla glass 2320.

Above 90% samples are delivered within 7 days.

For mass production, it’s always 15days

Q9: Specification Of Custom Gorilla Glass

A: The production information of gorilla glass (2320) and 4(5318)are enclosed. Please download for your reference.

Q10: What’s the unit of Haze ?

A: Haze refers to percentage of incident transmission light which deviates more than 2.5°accounts for total incident transmission light, the unit symbol is %. The higher the haze is, the lower the gloss and the resolution is.

Q11: Is it possible to print on the side of AG glass ?

A: No matter it’s single side AG glass or double sided AG glass, both can be silkscreen printed.

Q12: How Does FELIX GLASS Ensure The Glass Quality ?

A: To ensure the quality of custom gorilla glass and anti glare glass.

We will make full inspection after every procedure, IPQC and make spot check before delivery.

ISO9001:2008 quality management system is strictly carried out.

Q13: MOQ ?

A: 100pcs-1000pcs. We will provide you 10pcs samples in prototype stage

Q14: What’s the tolerance ?

A: Dimension: ±0.05mm ( 5”)

Printing: ±0.1mm

16.How many days to deliver custom anti glare glass ?

For custom anti glare glass, single side etching and double side etching.

FELIX GLASS import high quality raw material abroad, the applicable kinds are very wide. The lead time depends on the current stock, please kindly contact sales.

Q15: How Is The Processing Capability ?

A: For custom gorilla glass, gorilla glass 3, gorilla glass 4 and anti glare glass.

FELIX GLASS provide CNC machining,chemical strengthening,multi-color printing, AF coating, AR coating, anti glare etching and double side 3M tape service.

A. CNC machines to process any desired shape. Chamfer / Bevel/Holes etc.

B.Chemical strengthening to make glass stronger and tougher, with best performance of anti-scratch and anti-impact.

C.Multi-color printing technology to print any color on one glass once Pantone number is provided

D.Anti-fingerprint coating to keep surface clear and wipe fingerprints easily

E.Anti-reflective coating to increase the transmittance and reduce reflection of glass

F.Double side 3M tape to assemble the glass with other parts well

Q16: What’s the difference between single side AG glass and double sided AG glass?

A: FELIX GLASS AG glass is immersed etching. Technically speaking, we have to cover another side when we’re etching single side AG glass.

Q17: Will the gloss be varied after assembly.

A: If you bond the glass with other parts fully by optical bonding, the gloss will vary,the gloss of double side AG glass will increase by 10-20. If it’s single side AG glass or bonded half, the gloss varies small.

>>FAQ-2:
