MA820 TC Plan Achromat LWD 4X Objective ? for TC-5000 Series

N.A. 0.13, F.L. 49.90mm, W.D. 17.3mmThe MA820 is a TC LWD Planachromat 4X objective that is compatible with the TC-5000 and TC-5000C series. It has a parfocal distance of 45mm, a din standard 0.7965″ (20.1mm) diameter threads, 36 TPI and 55° Whitworth. NOTE: Meiji Techno offers objectives made in our main factory Meiji Techno in Saitama, Japan with strict ISO9001 standards and Japanese optical quality.  When choosing a proper microscope objective, it is important to keep in mind that objectives are designed by a microscope company to integrate with a particular microscope.  Before interchanging objectives, it is imperative to check the tube lens design and focal length and the threading type of the objective being replaced.  Please note that the optical performance of each objective may vary from the engraved specifications when integrated with components and systems from different microscope manufacturers.  Multiple optical factors including the microscope objective, tube lens and eyepiece together define the magnification of a system

Brightfield:
The simplest of all the optical microscopy illumination techniques. Sample illumination is transmitted (i.e., illuminated from below and observed from above) white light and contrast in the sample is caused by absorbance of some of the transmitted light in dense areas of the sample. Brightfield microscopy is the simplest of a range of techniques used for illumination of samples in light microscopes and its simplicity makes it a popular technique. The typical appearance of a brightfield microscopy image is a dark sample on a bright background.

Phase Contrast:
An optical microscopy technique that converts phase shifts in light passing through a transparent specimen to brightness changes in the image. Phase shifts themselves are invisible, but become visible when shown as brightness variations. When light waves travel through a medium other than vacuum, interaction with the medium causes the wave amplitude and phase to change in a manner dependent on properties of the medium. Changes in amplitude (brightness) arise from the scattering and absorption of light, which is often wavelength-dependent and may give rise to colors. Photographic equipment and the human eye are only sensitive to amplitude variations. Without special arrangements, phase changes are therefore invisible.

The TC-5300 & TC-5400 Series are suitable for viewing colorless and transparent specimens and live cells. The TC-5300 & TC-5400 Series is a contrast-enhancing optical technique that can be utilized to produce high-contrast images of transparent specimens such as living cells, microorganisms, thin tissue slices, lithographic patterns, and sub-cellular particles (such as nuclei and other organelles). In effect, the phase contrast technique employs an optical mechanism to translate minute variations in phase into corresponding changes in amplitude, which can be visualized as differences in image contrast. One of the major advantages of phase contrast microscopy is that living cells can be examined in their natural state without being killed, fixed, and stained. As a result, the dynamics of ongoing biological processes in live cells can be observed and recorded in high contrast with sharp clarity of minute specimen detail.

Epi-Fluorescent:
Microscope with Epi-Fluorescence is an optical microscope that uses fluorescence and phosphorescence instead of, or in addition to, reflection and absorption to study properties of organic or inorganic substances. The “fluorescence microscope” refers to any microscope that uses fluorescence to generate an image, whether it is a more simple set up like an epifluorescence microscope, or a more complicated design such as a confocal microscope, which uses optical sectioning to get better resolution of the fluorescent image.
