Imaging Optics
Objectives
The objective lens of VenusLab microscope is the core imaging component of an optical microscope. It is responsible for collecting the reflected/transmitted light from microscopic samples and converging it to form an image. Working in synergy with the microscope camera, it enables "high-magnification and high-definition microscopic observation".Different from other optical components, it directly determines the imaging resolution and clarity, and serves as a key element in microscopic analysis for biology, materials science, and industrial applications.
