The main reason index matching coatings are important is that such coatings increase the light transmission through the coated substrate. The index matching coatings contain a layer of SiO2 (quartz) as a top coating and the end result of that is the the total transmittance is increased noticeable amounts.
How does this kind of coating work?
An ITO only coating has associated with it, a particular transmittance. An ITO coating only is quite reflective and when the quartz coating is applied, it adds antireflection properties which means that what is no longer reflected, will be transmitted, and that is the mechanism by which a quartz coating increases the transmittance.
What does this mean in terms of microscopy?
Simply put, the index matching coating increases transmittance through the slide, which for some experiments, can be very very importance.
These index matched slides are offered only with busbars.
We offer standard off-the-shelf slides with index matching coatings but we can also manufacture custom index matching coatings.We can take your substrates (or supply them for you), coating them with the specified resistivity followed by the quartz coating of 80 nm. Note that the 80 nm can be varied to meet customer requirements. Let us know your requirements so that we can get back to you with pricing and delivery time.
Presently we can supply the index matching coating in the form of off-the-shelf microscope slides (1" x 3" in size) or on your custom substrates which could be glass, quartz, or even certain plastics such as polyester, acrylic, and polycarbonate. If you require something special, let us know your requirements.
