Windows

Windows are primarily used to protect more expensive optical parts from harsh environments or debris. These optical parts could include lenses, mirrors, or other components that are integral to the functioning of an optical system. The environments these systems operate in can often be harsh, with factors such as dust, moisture, or even physical impact posing a threat to the delicate optical parts. In such scenarios, windows act as the first line of defense, shielding these parts from potential damage.

However, the role of windows extends beyond just protection. They also have the task of transmitting radiation with minimum losses. This is a critical aspect of their function, as any loss in the transmission of radiation could lead to a decrease in the efficiency of the optical system. To ensure that the radiation is transmitted effectively, the optical component must be designed and manufactured with precision.

For this reason, protective windows are made of carefully chosen material. The choice of material is dependent on several factors, including the type of radiation that needs to be transmitted, the environmental conditions the window will be exposed to, and the specific requirements of the optical system. Some common materials used for these windows include glass, quartz, and various types of crystals.

In addition to the material, the windows are also AR/AR coated for the specific spectral range used in the application. This is crucial for ensuring that the maximum amount of radiation is transmitted through the window, without being lost due to reflections.

The specific spectral range for which the window is coated depends on the application of the optical system. For instance, if the system is designed to operate in the visible light spectrum, the window would be coated for this specific range. On the other hand, if the system operates in the infrared or ultraviolet spectrum, the coating would be tailored for these ranges.
