50X Infinitely Long Working Focus Flat Field Achromatic Objective Lens

Product specification:

Microscope objectives are the most important component of an optical microscope, as they are responsible for primary image formation and play a central role in determining the quality of images that the microscope is capable of producing. The objective lens is also a tool for determining the magnification of a particular sample and the resolution of the lower fine specimen details that can be observed in the microscope.

In most laboratory microscopes, achromatic objectives are used. It is brought into a single common focus; These objectives correct for axial chromatic aberrations at two wavelengths (approximately 486 and 656 nm, blue and red, respectively). In addition, the achromatic objective is corrected in the color green spherical aberration (546 nm; See Table 1). The limited correction of achromatic objectives can lead to significant artifacts when examined and imaged with color microscopy and microphotography of specimens. If the focus is selected in the green region of the spectrum, the image will have a red magenta halogenation (often called a residual color). Achromatic objectives produce the best results through a green filter for light (usually an interference filter), and are used when these objectives are used for microphotography of black and white film. The lack of a correction field (or flat field curvature) further hampers achromatic objectives. In the past few years, most manufacturers have begun to offer flat field corrections for achromatic objectives and give these corrected flat field achromatic objectives the name.
