Description

The MT4210EL Series microscopes feature a new computer engineered rigid frame that incorporates low positioned coaxial coarse/fine focus controls and ergonomic stage design for maximum efficiency and comfort while also providing an extremely stable operating platform.  Ergonomically designed, precisely manufactured and simple to use stage and coarse and fine controls, The MT4210EL Series was designed to meet the demands of researchers and clinical laboratory specialists and provides functionality and operational ease. Viewing high quality images, sample changing and photomicroscopy are all conducted with ergonomics in mind. High luminescent LED illumination reduces need for frequent bulb replacement but still provide rugged durability and long life span.

The phase contrast annulus is used in the substage condenser on Meiji Techno’s upright microscope within the condenser turret.  The Phase ring in the condenser must be specifically matched to the particular Phase objective equipped with a corresponding phase plate annulus.  For example, the Phase 10X and Phase 20X both of which contain a phase plate will require a condenser annuli having different diameters that correspond to the objective magnification and N.A. (Numerical Aperture). By properly matching the Meiji Techno Condenser annulus to the objective phase plate, the Meiji Techno Phase microscope can be aligned to superimpose illuminating light rays passed through the annulus onto the Phase ring of the objective to achieve proper Phase contrast illumination.

The Ph1 condenser annulus , which contains the smallest aperture, is designed to be used with the lower power 10X and 20X Phase objective. Intermediate magnification objective  40X Phase utilize the Ph 2 annulus, while the highest power and N.A. 100X objective require the Ph 3 annulus, which requires the largest phase annulus.

• The Ph1 position in the Phase Condenser Turret facilitates Objectives Phase 10X and Phase 20X
• The Ph2 position in the Phase Condenser Turret facilitates Objectives Phase 40X
• The Ph3 position in the Phase Condenser Turret facilitates Objectives Phase 100X

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.
