ML5870 Halogen Binocular Brightfield/Phase Contrast Biological Microscope

DISCONTINUED ON 10/5/2018The recommended replacement for ML5870 is the MT4210H or MT4210L. The ML5870 is a Phase Contrast & Brightfield Binocular Laboratory Compound microscope with a High Intensity Koehler Halogen 12V 50W illumination for applications that demand a lot of illumination. Equipped with a reverse facing quadruple ball bearing nosepiece is one of our most rugged fully equipped microscope systems from Japan. High resolution DIN Standard BF Phase objectives offer crisp, clear, high Phase contrast & Brightfield images and are offered as part of the standard package. It offers many high performance features and a robust rectangular base for stability. A built in integrated Koehler illuminator with a field iris and 12V 50W Halogen lamp and variable intensity control is provided standard equipment to complement the BF Phase optics. A green monitor lamp is lit to indicate that the lamp is on for easy on/off recognition in any laboratory setting. The low voltage, high intensity, pre-centered halogen lamp provides high level illumination can be adjusted to maximize the evenness of the bulb illumination and is readily accessible for a quick bulb replacement. The ML5870 Series also features a specially designed Zernike Phase turret condenser, N.A. 1.25 with centerable phase annuli for 10X, 20X, 40X with brightfield position with iris and filter tray for 29.8mm. The die cast metal stand has a chemical resistant finish and is the most, durable finish in the market today. Equipped with low position factory calibrated coaxial coarse and fine focus controls, tension adjustment and a built in stage stop lever to protect the specimen and objectives from accidental damage during use. The ML5870 Series Laboratory Biological Microscope is a versatile and modular system designed to accept a wide variety of optional accessories and is backed by Meiji Techno’s Limited Lifetime Warranty.

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 ML5000 Series has a Koehler Halogen 6V 30W or A 12V 50W illumination with a reverse facing quintuple ball bearing nosepiece and auto voltage sensing power supply. High resolution DIN Standard SM Plan objectives offer crisp, clear, high contrast images and are offered as part of the standard package. A built in integrated Koehler illuminator with a field iris and 6V 30W/12V 50W Halogen lamp and variable intensity control is provided standard equipment to complement the SM PLAN optics. The low voltage, high intensity, pre-centered halogen lamp provides high level illumination can be adjusted to maximize the evenness of the bulb illumination and is readily accessible for a quick bulb replacement. Flat-Top Mechanical stage with 171mm and 140mm rectangular stage with movement of 80mm (X) x 52mm (Y) with drop down Ergonomically placed low positioned coaxial controls and a detachable specimen guide.
