Technical glasses: From carrier material to high-tech product.

Your applications and intended use: based on your ideas we will develop the optimal solution with refined, technical glasses of MICROS Optics. Using the latest technology and consequently implemented process optimization, we can offer you the most economical solution. We deliver the entire range of glass refinement as a single component or large series of uniformly tested quality.

We will take care of what is important: high resistance to acids, alkalis, organic substances and corrosive environment, high electrical resistance, enormously long-term robustness, transmission and reflection, scratch resistance and mechanical stability – just to mention a few things.

Performance list

Flat or float glasses – such as D263 T eco, Borofloat 33, Microfloat, Optifloat, Optiwhite – are manufactured today with a range of flatness and parallelism which are adequate for many technical applications in development and industry. That is why MICROS Optics offers, besides optically polished plano plates, also these glasses in available dimensions.

Anti-reflective coated plates or glasses, reflective plates or front surface mirrors as well as beam splitter plates are cut according to client-specific dimensions after the coating process.

Thermal tempering / Chemical strengthering

As a result of thermal or chemical treatment glass plates turn into safety glass which possesses additional beneficial properties.

Thermal tempering

Design	The glass substrate is heated to a defined temperature and then allowed to cool rapidly in air; the glass surface develops compressive tension, resulting in tensile stress at the core of the glass (= annealed glass)
Properties as per DIN EN 12150-1	High resistance to temperature changes High resistance to flexural yield High impact resistance High resistance to scratches In case of excessive stress the glass breaks into small pieces; this prevents the risk of injury to a large extent
Material	Floatglass, Borofloat glass, flat glass, colour glass (e.g. finger jointed heat absorbing filter)
Metrology	See Test/Measurment

Chemical strengthering

Design	Ions are exchanged on the surface of the glass by a defined treatment in salt bath; this creates enormous compressive forces which improve the properties of strength of the glass
Properties	High resistance to temperature changes High resistance flexural yield High impact resistance High resistance to scratches This facilitates often the use of thinner glass thicknesses Later printing or coating is possible
Material	Thin glass, floatglass, Borofloat glass, colour glass, optical glasses

Anti-reflective glass plates

For many technical applications, MICROS Optics offers single-side and double-side anti-reflective glass plates. Disturbing surface reflections are eliminated to a great extent by interference optical coatings.

Optically polished plane and plane parallel plates with AR coatings; see Plano optics.

Application	In the entire industry for windows, inspection glasses or for special functions in your systems
Substrate material	Thin glass, floatglass, Borofloat
Dimensions	Thickness 1 to 6 mm Cut as per client’s requirements: round, angular, elliptical...
Designs	Standard for the UV and VIS spectral range; other wavelengths on request
Adhesion	According to DIN ISO 9211-4; S 02
Abrasion resistance	According to DIN ISO 9211-4; S 03
Temperature resistance	Depending on the substrate material up to 300 °C
Metrology	See Test/Measurement

Front surface mirrors

For many technical applications, MICROS Optics offers front surface mirrors with protected Aluminium as the reflective material. Besides, the protective layer reinforces the reflective properties of Aluminium. Light is reflected by the mirror coating directly. Occurrence of double images is thus avoided.

Optical polished mirrors; see Plano optics.

Beamsplitter plates

For many technical applications, MICROS Optics offers neutral beamsplitters on flat glasses.

Optically polished plane and plane parallel plates with beamsplitter coatings; see Plano optics.

Application	Beamsplitters disperse the light rays within the given light spectrum; corresponding signals or images are generated at different locations.
