High power objective definition
WebWith low-power objectives in the range 2X to 5X, the illumination cone will have a diameter between 6-10 mm, while the high-power objectives (60X to 100X) need a highly focused light cone only about 0.2-0.4 mm in diameter. With a fixed focal length, it is difficult to achieve this wide range of illumination cones with a single condenser. http://bioweb.uwlax.edu/aplab/Lab-Unit-01/Lab-01-04.html

Did you know?
WebAs a general rule working distance decreases and total magnification increases due to the higher numerical apertures associated with high power objectives. Working distances can vary among objective lenses depending on the manufacturers even for objectives of the same magnification level. WebObjectives also always carry the engraving for the numerical aperture (NA) value. This may vary from 0.04 for low power objectives to 1.3 or 1.4 for high power oil-immersion apochromatic objectives. If the objective carries no designation of higher correction, one can usually assume it is an achromatic objective.
WebHigh-power microscopes (compound microscopes) are the typical microscopes seen in laboratories and on television, and magnify in the range ×40 to ×1000. ... The overall magnification of the system is the objective magnification multiplied by the eyepiece magnification. Objectives usually come in magnifications from ×4 to ×100 and eyepieces ... WebApr 27, 2024 · A high-power objective lens magnifies 40x, with total magnification 400x if the eyepiece lens is 10x power, and it is ideal for observing very fine detail, such as nerve cells in the retina or the striations …

WebThe higher the NA becomes, the higher the resolving power of the objective, when the resolving power is defined as the power to recognize two points. The higher the NA, the brighter the image acquired. In turn, the higher the NA, the shallower the depth of focus on a detector. View chapter Purchase book Digital Microscopy
WebNov 24, 2008 · Working distance can range from 50 mm for dissecting or stereo microscope objectives to less than 0.1 mm for high-power oil immersion objectives. It decreases as magnification, resolution and numerical aperture increase. Microscope objectives are usually designed with short working distances.
