Optical lens barrels are mainly used in optical imaging systems, lasers, astronomical observation instruments, microscopes, telescopes and other fields. For example, optical barrels are commonly used in camera lenses, objective lenses and eyepieces of microscopes, focal length adjustments of telescopes, etc. Its role is to provide stable support and fix the optical components, while making necessary adjustments and controls to achieve precise imaging and observation.Optical alignment shims or positioning pads provide precise positioning and alignment to ensure the accurate and reliable distance and angle between optical elements, thus ensuring the performance and precision of the entire optical system. Optical alignment shims usually have very high flatness and surface quality to ensure that optical elements do not produce optical deviations or affect imaging effects when in use. In the manufacturing and assembly process of optical devices, optical alignment shims are one of the indispensable key components.
