Manufacture of dichroics, areas of application and specifications

Everything you wanted to know about the features and specifications of our products

The durability of the dichroic filter effect is unlimited. This is because the coatings are inorganic. They are produced using a dip coating process. The metallic alcohol-based coating solutions used in this process are converted in a thermal process at 480°C into bonded metallic oxide layers. Therefore they cannot be altered by heat or UV rays.

The coated glass is highly resistant and durable. It can be further processed using virtually any common glass processing method.

What is a dichroic filter and what effect does it have? 

Transmission und Refelxion bei dichroitischen Filtern

Colour effect glass, lighting filters and filters for the presentation of goods are dichroic (from the Greek ‘dichroos’ = bicolour) filters. The technology allows virtually every colour of the spectrum to be generated, both the additive (red, green, blue) and the subtractive (yellow, magenta, cyan) colours.  This effect is based on the interference of light waves on thin, optically transparent layers, in the process of which white light is then refracted in colour.

The colours are the result of the superposition of light waves, which are reflected both on the surface of a corresponding layer and on its lower boundary. If two wave peaks are superimposed, the waves intensify (constructive interference). However, if a wave peak encounters a wave trough, the rays cancel each other out (destructive interference). This prevents the incident light from being absorbed and transformed into heat rays. This is unlike the effect of traditional colour filters, which is based on the absorption of entire spectral ranges and can lead to strong heat build-up.

Processing guidelines

Dichroitisches Glas Bearbeitungs-Richtlinen

The sol-gel process is used to achieve coatings on glass that are highly resistant and durable. The coated glass can be further processed using many common glass processing methods. When doing so, please observe the following guidelines.

In general:

Since the applied coating or coating package is very small (0.05 µm to 1 µm), mechanical damage can occur to the coating during processing. Processing must therefore be carried out under extremely sanitary conditions. Exposure to abrasive substances such as grinding dust, glass fragments or metal particles on the coated surfaces should always be avoided.

Scratches, breakage

Coated glass can get scratched and break just like normal, uncoated glass. The cutting and breakout table must be clean; the glass plates must only be moved across the table using an air cushion to prevent scratches. Dust that has settled on glass plates after a storage period should first be removed by cleaning. Never use a hand broom or dry cloth.

Grinding

Coated glass plates can be ground individually or in a block. When grinding individual glass plates, make sure that the tool-holder of the grinder does not scratch the surface. When grinding the glass in a block, paper inserts or putty can be used. Use only acid-free paper. Alcohol-based solvents can be used to loosen the putty. Do not use acids or lye that could corrode the surface of the glass or affect the adhesion of the coating.

Processing into laminated safety glass

can be done without any constraints. There is no known interaction between the coating and common bonding materials (PVB or resins).

The thermal hardening

of the coated glass and processing into toughened glass are generally not possible, since the required high temperature tends to cause clouding or cracks. In specific cases, certain filter types can be thermally toughened, taking into account the respective coating after thorough testing and precisely defining the toughening parameters.

The chemical hardening

of coated glass is generally  not possible.

Any size of filter disc

Unterschiedliche Größen von Glasscheiben mit Inlays aus dichroitischen Filtern

can be chosen. The maximum dimensions of an individual filter disc are 5.80 m x 2.55 m, as laminated safety glass without joint: 1.4 m x 1.0 m. Larger areas can be obtained by butt joining several filter discs together.

Different colours can also be combined in one disc by butt joining. It is also possible to combine them with semi-transparent mirrors and/or transparent glass.

We can match your specifications for perfect integration, with or without a frame, and completely assembled according to your requirements.

We can also apply dichroic coating to glass pipes.
