Principle:
Cemented lenses are also called achromatic lenses. Cemented lenses are used to minimize or eliminate chromatic aberration. Its achromatic design also helps to minimize spherical aberration. Glue two or more components together during the manufacturing process. Compared with a single lens, an achromatic lens can form a smaller spot
Features:
The role of the cemented lens in the optical system is: focusing, collimation, imaging.
Application:
Achromatic lenses are suitable for various applications such as fluorescence microscopy, image relay, inspection or spectroscopy.
Positive cemented lens:
Negative cemented lens:
