Enhancing Optical Adhesives
Several key factors contribute to the reliability and performance of optical adhesives. These include the selection of high-precision components, robust adhesive technologies, and the future advancement of your custom optical systems.
What Are Optical Adhesives?
Optical adhesives, also known as optical cements or optical glues, are substances used to bond two or more optical elements together per specific technical requirements. The optical elements may be lenses, prisms, window pieces, or any number of other parts, and the gluing procedure achieves various optical functions. For example, two multi-order wave plates can be glued together to create a zero-order wave plate. In cases where complex prisms cannot be manufactured as a single piece, multiple prisms can be glued together to enable more intricate optical path conversions. Additionally, the bevel of a right-angle prism can be coated and glued to form a cube, facilitating the creation of a wide-band polarized or unpolarized beam-splitting prism.
Key Takeaways:
- Optical adhesives are used in optical gluing to bond optical components like lenses and prisms for various functions, such as creating achromatic lenses and complex prism assemblies.
- Key to reliable adhesives are high-precision component processing, dependable adhesive technology, and future advancements like automation. The process involves cleaning, dispensing adhesive, fitting, centering, wiping, UV curing, and inspection.
- Careful alignment of optical components minimizes aberrations and ensures quality.
- Optical adhesives improve performance by reducing reflections and simplifying manufacturing in instruments like cameras and telescopes.
