MIRONA® semi-transparent mirrored glass is made with SCHOTT’s proprietary sol-gel dipping technique, making it chemically stable, able to handle bumps and abrasions, and simple to maintain. With a range of processing options, from thermal toughening to lamination, MIRONA® can be customized to your requirements.

Tough, beautiful and easy to maintain

Stabilizing process

MIRONA® is produced using the quality-enhancing sol-gel dipping method. The glass is plunged into metal oxide solutions and the metal oxide coating layers are burned in at 450°C to 500°C. These layers are much purer and mechanically and chemically more stable than glass processed with conventional PVD techniques.

Durable for longer

MIRONA® is a highly advanced glass but its sophistication is matched by its robust constitution. The glass possesses high levels of resistance to chemicals and abrasions compared to mirrored float glass, and offers a long service life.

Toughening treatment

MIRONA® can be made even stronger by a choice of treatments. For example, it can be thermally toughened compared to mirrored float glass and processed into laminated safety glass.

Easy maintenance

It’s simple to maintain that MIRONA® sparkle. MIRONA® is much easier to clean than other similar glass on the market – just wipe using any regular glass-cleaning agent or towel moistened with a 1:1 mixture of denatured alcohol and water.

Product Range

The MIRONA® collection of semi-transparent mirrored glass is incredibly versatile. From MIRONA® Beamsplitter for high-resolution displays to MIRONA® High-Reflective for a higher contrast, the innovative series provides a range of qualities for a variety of applications.

MIRONA® Standard

This extra-clear, low-iron float glass with optical interference coating on both sides offers defined reflection (34%) and transmission.

MIRONA® High-Reflective

An enhanced version of MIRONA® Standard for when higher mirroring is required, this has a high-reflective optical interference coating that offers 55% reflection.

MIRONA® Beamsplitter

MIRONA® Beamsplitter is an extra-clear, low-iron glass with an anti-reflective coating on one side and a high-reflective coating on the other for defined 36% reflection and transmission. Specially developed for high-resolution displays, the result is almost no irritating double reflection.

MIRONA® High-Reflective One Side Coated

Coated on just one side to produce MIRONA® Beamsplitter as a laminated safety glass.

How it Works


The combination of two functions that traditionally juxtapose one another – reflection and transmission – is made possible by the special Sol-Gel-Dipping procedure that SCHOTT has developed: The glass is initially dipped in various metal-oxide solutions and then subsequently burned together, producing a striking effect. When the space behind the glass is dark, SCHOTT MIRONA® is an elegant mirror, but when lit, the light transforms it into a transparent window. 

The strength of the light and the ratio between the light sources both behind and in front of the pane determine the ultimate functionality of the glass.


Reflection: the viewer sees their mirror image.

Where is the strongest light source?

In front of the glass, MIRONA® is an elegant mirror, despite just 34% reflection. But behind the glass, MIRONA® opens up an additional layer for imagery, products and information.

Thermal Toughening

Glass of 3 mm thickness or more has the option of undergoing thermal toughening. This results in a 3-4 times more mechanical and thermal strength compared to non-toughened glass.

 Thermal toughening


Chemical Toughening

Glass of less than 3 mm can undergo chemical toughening. This process also creates surface compressive pressures but through ion exchange in a bath of molten salt.

Chemical toughening 


Screen Printing

Screen printing is used for customer-specific motifs, passe-partouts, logos, and more. Ceramic colors are suitable for thermal toughening, while organic colors are suitable for chemical toughening.


Screen printing 



Lamination involves the bonding of two or more glass plates in a vacuum using an adhesive layer.




General Introduction

1. What are the main features of SCHOTT MIRONA®?

  • SCHOTT MIRONA® magically transforms itself from a mirror to a transparent window. A unique combination of reflection and transmittance enables an ingenious presentation of space and objects.
  • Available on various types of materials (e.g. on the basis of extra-clear, low-iron float glass or grey glass).
  • Available in four unique coatings. Mirroring intensity varies depending on the degree of reflection:
    • MIRONA® Standard
    • MIRONA® Beamsplitter
    • MIRONA® High Reflective
    • MIRONA® High Reflective One side coated
  • MIRONA®Beamsplitter is specially designed for high-resolution displays.
  • The coating is highly chemically resistant.
  • Transforms from a transparent display to a mirror without any electricity.
  • Maintenance-free!
  • Easier to clean than competitive products. 
  • Diverse processing options (e.g. laminated safety glass, insulating glass, thermally toughened). 

2. What applications is the glass recommended for?

  • Aesthetic interior styling (design elements such as partition walls, wall paneling or design objects).
  • As silver mirrors with advanced functionality (e.g. consumer electronics, cover panels for use in televisions and projection screens, etc.).
  • Solutions for the lighting industry as decorative and functional light covers.
  • MIRONA® Beamsplitter is an excellent product for use in teleprompter applications
  • For touchscreens (CAP /P-CAP technology).



3. When should SCHOTT MIRONA® Standard be used?

MIRONA® Standard with 34% reflection is your entry into the magical world of mirroring glass from SCHOTT.

4. When should SCHOTT MIRONA® Beamsplitter be used?

MIRONA® Beamsplitter delivers 36% reflection on one surface; the other surface is coated with an anti-reflective coating. This avoids ghost images from the backside of the glass.

5. When should SCHOTT MIRONA® High Reflective be used?

If higher mirroring is required, use MIRONA® High Reflective with 55% reflection. 

6. When should SCHOTT MIRONA® High Reflective One Side Coated be used?

MIRONA® High Reflective One Side Coated should be used when laminated safety glass or lamination is required. This avoids reflections from the back or PVB side.



7. Does SCHOTT MIRONA® have the same reflection color rendering as a standard mirror?

No, the reflected image appears a bit darker than it is. This is because, in contrast to SCHOTT MIRONA®, standard mirrors use a silver layer so normally have more than 90% reflection.

8. How can SCHOTT MIRONA® be installed in front of a display or TV?

MIRONA® should be integrated into a frame. The frame of the display is normally hidden by a passe-partout to conceal the adhesive joint between the frame and glass. The construction is installed with a space between the display and the glass. This space and the ambient lighting conditions affect the visual results.

9. With respect to SCHOTT MIRONA® Beamsplitter, where should the anti-reflective side be?

The AR side should normally be on the non-reflective rear side to avoid reflection from the rear. Reflection then occurs only from the front.

10. How do I avoid double images with SCHOTT MIRONA®?

To avoid double images when using MIRONA® Beamsplitter, the high-reflective side needs to be placed facing the user; the anti-reflective side should face the display. An anti-glare display (non-glossy and/or matt) is recommended to avoid reflection from the display itself.

11. How can I conceal unwanted items around the screen (for instance the TV brand, etc.)?

Either by putting a passe-partout behind the MIRONA® glass, for example cardboard or foil (the most simple and flexible solution).
or by printing/painting the glass to reduce the screen surface.

IMPORTANT: Please make sure that the color of the masking or print/paint matches the color of the screen when it is switched off!

12. How can I avoid seeing a difference between the color of the passe-partout and the screen when the screen is turned off?

By optimally matching passe-partout color and the display color when the screen is switched off, and by leaving as little space as possible between MIRONA® and the screen.

13. How can we retain the functions of the remote control on the screen if the IR sensor is concealed?

By using a material (interlayer or print /paint) which is transparent to infrared signals. Alternatively, leave a small opening in the print and position it in front of the IR sensor.



14. Which SCHOTT MIRONA® types can be laminated?

In principle, all types of MIRONA® can be laminated. We can provide you with more information on the test reports from the German testing institute Friedmann and Kirchner on the lamination of MIRONA®. Using PVB or EVA film as an interlayer fulfils EN 12543-2 requirements. Laminating MIRONA® makes sense when, for example, a MIRONA® Beamsplitter with VSG properties is to be produced by combining MIRONA® High Reflective One Side Coated (Level 1) and AR One Side Coated (AR at Level 4).

15. Is it possible to print on a coated surface?

Yes, it is. The color shade may be slightly affected by the coating.

16. What kind of material is recommended for the passe-partout?

Cardboard, foil, organic and ceramic printing is recommended.

17. What kind of printing can be applied to SCHOTT MIRONA®?

Ceramic and organic printing can be used with MIRONA®. The technology for applying the ink (screen printing, digital printing, painting) doesn’t really matter.

18. Which SCHOTT MIRONA® types can be thermally toughened?

All types of MIRONA® can be thermally toughened. Compared to MIRONA® Standard, MIRONA® High Reflective has a more complex layer structure, which means that only tempering furnaces with multi-zone temperature control and temperature monitoring are suitable for toughening. During thermal toughening, the reflective color may change slightly, which cannot be avoided due to the process.

19. Can SCHOTT MIRONA® be used outdoors?

All types of MIRONA® (except MIRONA® Standard) are suitable for outdoor use. They have been tested at the Institut für Fenstertechnik (ift) in Rosenheim, Germany according to ISO 1096-2 and is classified as class A. DIN EN 1096-2 describes the testing and durability of coated glass in the construction industry.
