Q: Why is magnification important in microscope objectives? A: Magnification determines the size of the observed area and the resolution of the microscopy system. Lower magnification provides a larger field of view but lower resolution, while higher magnification offers finer details but a smaller field of view. Back to top page
Q: How does numerical aperture (NA) impact microscope objective performance? A: Numerical aperture measures the objective’s ability to gather light and determines resolution. Higher NA results in superior resolution, allowing finer distinctions in images. NA = n × sinθa, where θa represents the maximum acceptance angle and n denotes the refractive index of the immersion […]
Q: What is the significance of conjugate distance in microscope objectives? A: Microscope objectives are available in two primary types: finite conjugate distance and infinite conjugate distance. Finite conjugate objectives are cost-effective and suitable for simple microscopy systems. In contrast, infinite-corrected objectives are ideal for advanced applications, integrating optical components in the infinity space for […]
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 […]
