High power objective lenses in microscopes typically have magnifications ranging from 40x to 100x. These lenses are used for detailed examination of specimens and provide high levels of magnification, allowing for close-up views of fine structures and cellular details. Keep in mind that the actual magnification will also depend on the eyepiece being used in conjunction with the high-power objective. For example, if you're using a 10x eyepiece with a 40x objective, the total magnification will be 400x.

14. Ultraviolet (UV) Radiation Objectives: Objective lenses tailored for the ultraviolet (UV) radiation range are crafted for brightfield microscopy and find applicability in laser-based tasks. These UV objectives boast features like infinity correction, long working distance, and a Plan Apochromat design. They excel in performance specifically within the ultraviolet spectrum (266nm) and also maintain high-quality imaging for visible wavelengths.

Choosing the right type of objective lens depends on the specific requirements of the microscopy application, including the type of specimen, desired level of detail, and any specialized techniques being employed.

Objective lenses are typically labeled with two numbers, such as 10x/0.25. The first number represents the magnification, indicating that the lens magnifies the specimen by a factor of 10. The second number is the numerical aperture (NA), which signifies the lens's ability to gather light. This combination of magnification and numerical aperture is crucial in determining the level of detail and clarity that can be achieved when examining specimens under a microscope.

DefinitionWhile the manufacturing and use of common spherical lenses (with both lens surfaces being part of surfaces of spheres, i.e. a spherical segment or spherical cap) are less complicated and expensive, the optical performance of spherical lenses is compromised by phenomena such as spherical aberration. So instead of a simple spherical lens, a more complex shaped lens is best suited for collimating and focusing tasks – an aspherical lens with at least one surface whose shape differs from a sphere. An aspheric lens surface typically is described by a radius of curvature and several parabolic or higher order terms.

The primary function of objective lenses in microscopy is to capture light emitted or reflected by the specimen. They then focus this light to form an enlarged image, which can be further magnified by the eyepiece lens. By adjusting the objective lens, users can achieve different levels of magnification, allowing for detailed examination of minute structures.

A scanning objective in microscopy refers to a specific type of objective lens used to observe specimens. It is characterized by a low magnification level, typically between 2x and 4x, and is designed to provide a wide field of view. Scanning objectives are commonly used for initial specimen location and overview. They allow for quick scanning of a large area to locate regions of interest before switching to higher magnification objectives for detailed examination. This type of objective is particularly useful in tasks where a broad perspective is needed before zooming in for more precise observation.

11. Stereo Microscope Auxiliary Objectives: Stereo microscope auxiliary objectives are supplementary lenses used to alter the magnification and working distance of a stereo microscope. They are designed to be easily interchangeable, allowing users to adapt the microscope's capabilities for different tasks.
