Q: What is an Infinity-Corrected Objective?
A:
An infinity-corrected objective is a specialized component in microscopy designed to work in tandem with an infinity-corrected tube. This objective offers an extended working distance compared to standard DIN-type objectives. Unlike traditional microscopes, where magnification is solely achieved through the objective and eyepiece lenses, the infinity-corrected objective produces collimated light before reaching the secondary lens assembly.
In this system, a lens assembly within the tube is crucial for forming the image from the objective. This setup allows the objective and microscope to be positioned farther from the sample, providing users with additional space to manipulate the specimen. However, it’s important to note that a tube lens is necessary for proper focusing. Without it, the system will not function effectively.
