MIRONA®
Product Range
The MIRONA® collection of semi-transparent mirrored glass is incredibly versatile. From MIRONA® Beamsplitter for high-resolution displays to MIRONA® High-Reflective Grey 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 Grey
This grey float glass has a high-reflective coating on both sides and absorbs more light, so providing a darker background and therefore a higher contrast.
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.

Transmission: contents behind the mirror become visible. |
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.
Finishing
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.
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.
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.
Laminating
Lamination involves the bonding of two or more glass plates in a vacuum using an adhesive layer.

Applications
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 Grey be used?
The grey glass has a high-reflective coating on both sides to absorb more light, which delivers a darker background and creates higher reflection.
7. 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.
Installation
8. 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.
9. 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.
10. 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.
11. 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.
12. 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!
13. 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.
14. 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.
Processing
15. 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).
16. Is it possible to print on a coated surface?
Yes, it is. The color shade may be slightly affected by the coating.
17. What kind of material is recommended for the passe-partout?
Cardboard, foil, organic and ceramic printing is recommended.
18. 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.
19. Which SCHOTT MIRONA® types can be thermally toughened?
Only MIRONA® Standard can be thermally toughened. MIRONA® High Reflective and MIRONA® Beamsplitter can also be thermally toughened using modern convection furnaces.
20. Can SCHOTT MIRONA® be used outdoors?
No, MIRONA® cannot be used outdoors. Laminated MIRONA® High Reflective One Side Coated with the coating facing the interlayer (and/or to the inner side) could serve as an alternative. The reflection of this setup is approx. 25%.
