(Update September 08, 2014: Optiwhite is a laminated glass with improved optical transmittance. This is achieved through the addition of iron oxide compounds, which improve the quality of the glass. Optiwhite glazing can withstand pressures of up to 0.1 bar . This means that Optiwhite is only suitable for very small, shallow Underwater windows.)

Glass needs to be very thick and laminated in order to bear water pressure. It has a greenish tint. Acrylic is optically superior and has no visible tint.

Acrylic has a higher impact strength than glass and does not shatter when exposed to high strains. Shattering into small, blunt chunks is desirable for applications in which tempered glass is used, e.g. in automobiles. However, shattering is not desired for the use of glazing underwater. The crack resistance is especially valuable, when large underwater windows are craned into their location. The installation of large and heavy glazing bears a certain risk for the installation company when using laminated safety glass. Point loads while hanging on the crane or due to uneven seating might lead to material failure. Acrylic is more tolerant to these forces and rather flexes then breaks. Acrylic's high impact strength, durability and applicability make it the ideal material even when human lives are at stake. Therefore acrylic is used in deep sea submarine windows.

CI Systems offers a cost effective and modular optical test bench to measure Modulation Transfer Function (MTF) and transmittance of optical components.

The condenser is located below the stage. It collects wavefronts from the light source and focuses them to illuminate the specimen evenly across the field of view.

It is also essential to choose the correct magnification. The most useful objective lens magnifications are x4, 10, 20, and x40.

Acrylic glass is often chosen as an alternative for laminated glass. Both Acrylic and laminated glass are transparent building materials which withstand high pressures and can be used for applications like aquariums in marine museums and yacht windows.

The thermal conductivity of acrylic is lower than that of laminated glass. In other words the thermal insulation of acrylic is better than of laminated glass.

Fine focus is a small knob that allows you to adjust the lens to make your image clearer. You can achieve a clear focus more often under a high-power magnification by adjusting the fine focus.

Because a high-powered microscope is also a compound microscope, it is vital to learn its different parts, functions, and jargon before setting them up.

Safety glass consists of multiple layers of mineral glazing, separated by plastic laminate. Normal plastic laminates are not resistant against UV and are especially sensitive to humidity.

Acrylic is a monolithic material made of organic substance, hence its nickname "organic glass". Plexiglas is a popular brand name for acrylic. Another one is Perspex©.

The surface of acrylic is softer and more easily scratched than mineral glass. It is advised to check the acrylic cleaning guidelines in order to prevent abrasive or chemical damage. It is easy to polish acrylic in order to remove blemishes. Scuffed mineral glass would on the other hand need to be completely replaced.

A high-powered microscope is just an ordinary compound microscope. It is considered high powered because of its two-stage magnification.

Laminated glass is made of several layers of mineral glass (also called flat glass, Borosilicate glass or "Echtglas"- real glass, in German). These sheets of glass are separated by transparent liners which are fused together. This makes them particularly strong and prevents inclusions. The materials used for the liner are PVB & SGP. Nowadays SGP is chosen for most applications, because of its hydrophobic properties.

There are view cases where safety glazing is a viable option, but in the vast majority of applications acrylic has proven to be superior when used for underwater.

The total magnification of a microscope is equal to an objective lens magnification multiplied by the eyepiece magnification. For example, if your eyepiece has 10x magnification and your high-power objective lens is 40x, the total magnification will be 400x.

Using acrylic outdoors exposes the material to potentially high amounts of ultraviolet radiation (UV). It is a common misconception that UV rays lead to the yellowing of acrylic glazing. This might be true for low quality acrylic. Plexiglas and other well known brands are immune even against high UV radiation. Up to 30 years are guaranteed by the manufacturer.

Place a microscope slide on the stage underneath the low power objective lens for more effortless adjustment under the high power objective.

Acrylic glass has a lower density, which can range from 1150-1190 kg/m³. This is less than half the density of glass which ranges from 2400 to 2800 kg/m³. Transportation and assembly of acrylic building materials is consequently easier and cheaper.

High-powered microscopes are mostly used in schools. They are used to examine small samples, such as bacteria, blood cells or other tiny life forms. They can also be used to view items that you cannot see with your naked eye.

Acrylic transmits more light than glass. Up to 92% of visible light is transmitted through acrylic. Mineral glass transmits 80-90%, depending on the type of glass and manufacturer. This is especially relevant, when comparing load bearing transparent materials with the same depth. These windows are usually several centimeters thick, which makes differences in the optical transmittance particularly noticeable. Bullet proof glass is a well known type of load-bearing glass and transmits, similarly to other types of mineral glass, a white- to green-type of light. This phenomenon is not observable with Acrylic.

When buying a compound microscope, there are many things you should consider. The budget is one. Commonly, microscopes that belong to a higher price range have better optics. That's why they are excellent investments.
