FAQs MIRONA® - semi-transparent mirrored glass

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 five unique coatings. Mirroring intensity varies depending on the degree of reflection:
    • MIRONA® Standard
    • MIRONA® Beamsplitter
    • MIRONA® High Reflective
    • MIRONA® High Reflective Grey
    • 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. The glass recommended for what kinds of application?
  • 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, etc.
  • MIRONA® Beamsplitter is an excellent product for use in teleprompter applications

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 backside / 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 standard mirrors use a silver layer and, in contrast to SCHOTT MIRONA®,  therefore normally have more than 90% reflection.


9. How can SCHOTT MIRONA® be installed in front of a display / 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 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%.
