Objectives are defined by a number of factors, some of which include the magnification, resolving power, numerical aperture and working distance. Magnification: the amount that the image is magnified by the objective. The range of useful magnification is arbitrarily defined as 500 to 1000 times the...
The present invention relates to microscope objectives and more particularly, to a high-magnification microscope objective with a magnification 100 and numerical aperture 0.9. Besides, for the microscope objective according to the present invention, aberrations, especially spherical and chromatic aberrations ...
Imaging large, cleared samples requires microscope objectives that combine a large field of view (FOV) with a long working distance (WD) and a high numerical aperture (NA). Ideally, such objectives should be compatible with a wide range of immersion medi
Objectives having a magnification factor below 4x are considered to be very low in magnification and may not be compatible with all microscope optical systems. Generally, Köhler illumination is difficult to achieve with low magnification objectives, which often require specialized matching condensers to...
Microscope - Magnification, Optics, Illumination: The limitations on resolution (and therefore magnifying power) imposed by the constraints of a simple microscope can be overcome by the use of a compound microscope, in which the image is relayed by two l
Microscope objectives provide fixed magnification for factory inspection or microscopy systems. View our available selection of microscope objectives at Edmund Optics.
Objectives are differentiated by their performance. They are classified on the basis of their optical properties, i.e., the light transmission, chromatic correction, image planarity, immersion media, magnification, numerical aperture, among others. There are international standards which define the classi...

Such devices are often optimized for viewing distant images with large magnification. The entrance diameter is important not only concerning the light gathering power, but also ultimately limiting the image resolution. Infrared viewers have objectives which are optimized for receiving infrared light. ...
It is, therefore, a primary object of the present invention to provide a microscope objective for which the flatness of image is made more favourable by correcting the astigmatic difference and curvature of field more favourably compared with known achromat microscope objectives with high magnification...
