Sapphire Window is a single crystal aluminum oxide (Al2O3). It is one of the hardest materials. Sapphire has good transmission characteristics over the visible, and near IR spectrum. It exhibits high mechanical strength, chemical resistance, thermal conductivity and thermal stability. It is often used as window materials in specific field such as space technology where scratch or high temperature resistance is required
Properties of Sapphire Windows
Optical Windows are used as viewports to protect other components within an optical assembly, instrument, or laser. In certain applications, optical windows are required to withstand harsh environmental conditions and provide high levels of performance and reliability. Sapphire window has several unique properties that make it the ideal material for these applications.
1. Synthetic Sapphire, the single crystal form of Al2O3, is one of the hardest materials ( 9 Mohs hardness). Because of its structural strength, the sapphire window can be made much thinner than other common optical windows, with better transmittance performance. |
2. High thermal stability and excellent thermal conductivity make the sapphire window suitable for the applications in high power. The loss in a sapphire window is less than in another common optical window. |
3. Sapphire windows can withstand considerably higher temperatures than most optical windows with zero degradation. |
4. Sapphire Windows will not get dark and lose their brilliancy when exposed to UV light. |
5. Sapphire windows are extremely stable and resistant to attack by strong acid due to sapphire's high dielectric constant. |
6. Sapphire windows offer wideband transmission from UV to Mid-IR (0.15-5.5µm). |
All these unique properties make sapphire windows the ideal material for extreme mechanical, chemical & optical applications. |

One of the main applications of cylindrical lenses is in ophthalmology, specifically, to correct astigmatic vision. When a person presents astigmatic vision, it is usually the result of a corneal deformation. An astigmatic cornea will have different focal points at different axes. It is then possible to use a cylindrical lens to change the focal point of one of the axes to overlap the second one.
2 . Laser Line Scanning
This is a technique that is used to capture the shape of a 3D object into a digital copy. It is particularly useful in manufacturing, prototyping, landscaping, and architecture. This scanning technique measures the deformation of a straight line created by a cylindrical lens when it is incident into a non-flat surface. By using cameras and triangulation, it is possible to measure the changes in the shape of our laser line and therefore estimate the shape of the object that we are measuring. If you would like to learn more about Laser Line Scanning please leave a comment.
3. Laser Scanning Microscopy
They are usually used in combination with acousto-optic deflectors, where the focal point of a variable lens (the acousto-optical elements) can change its position laterally without the use of movable parts. The cylindrical lens corrects the image and helps focus the light spot onto the correct plane for laser scanning microscopy.
