Key Questions to Ask When Ordering Wedge PrismsWedge Prisms: A Comprehensive Guide.
1. What is the desired wedge angle for the prism?
2. What is the required clear aperture size?
3. Do you need anti-reflection coatings on the prism?
1. The wedge angle of a prism refers to the degree to which the two faces of the prism are not parallel. It is an important factor to consider when ordering a wedge prism as it directly impacts the deviation angle of light passing through the prism. The desired wedge angle will depend on the specific application and requirements of the optical system.
2. The clear aperture size of a prism refers to the size of the area through which light can pass without obstruction. It is crucial to determine the required clear aperture size when ordering a wedge prism to ensure that it will meet the needs of the optical system. The clear aperture size should be chosen based on factors such as the size of the beam of light passing through the prism and the desired field of view.
3. Anti-reflection coatings are thin layers of material applied to the surfaces of optical components to reduce unwanted reflections and increase the overall transmission of light. When ordering a wedge prism, it is important to consider whether anti-reflection coatings are needed to improve the performance of the prism. The decision to add anti-reflection coatings will depend on factors such as the wavelength of light being used, the desired level of transmission, and the specific requirements of the optical system.
In summary, when ordering wedge prisms, it is essential to consider the desired wedge angle, required clear aperture size, and the need for anti-reflection coatings. By carefully addressing these key questions, you can ensure that the wedge prism you order will meet the specific needs of your optical system and deliver the desired performance.
