OMAX MD821 Series Phase Contrast Siedentopf LED Binocular Compound Microscope 40X-2000X Magnification with Built-in 3.0MP Camera
Key Features
- 40X to 2000X magnification range using brightfield objective lenses, and 100X to 2000X magnification using achromatic phase-contrast objective lenses
- A heavy-duty, ergonomic microscope for students and professionals with a built-in 3MP digital camera for watching real-time images on your computer while capturing photos and videos
- Along with the standard brightfield lenses, this phase-contrast version of the M8311 includes specialized objective lenses equipped with phase-rings, and a turret condenser with brightfield and phase-contrast settings.
- Professional features include a Siedentopf trinocular head for precise adjustments, a 2-layer mechanical stage with low-position controls, and coaxial coarse and fine focus for ergonomics and an efficient workflow.
- The bright LED light source provides cool, daylight-balanced illumination.
OMAX Digital Microscopes integrate advanced digital-imaging with precision optical microscopy. Digital integration promotes uniformity, and presents a simplified method for setting up and using microscopes.
OMAX provides a large range of solutions for education, research, and industry. Building on industry standards, we provide a full range of accessories to suit your needs.
The MD8211 digital-integrated compound microscope is designed for educational and professional use. The medium-sized profile offers streamlined ergonomics with plenty of working room. The heavy-duty metal build and enamel coating will last for many years through rigorous use. Optional upgrades are available including darkfield and phase-contrast kits. This phase-contrast model includes a specialized turret condenser and objective lenses used to enhance details in low-contrast specimens such as live cells and microorganisms.
Digital-Integrated Head
The microscope uses an adjustable binocular viewing head with a built-in 3MP camera. With the camera built in, there are fewer moving parts to worry about, and it only takes a single USB connection for setup with your computer. The included software allows you to view real-time images on your computer while capturing photos and videos.
To customize the microscope to your viewing comfort, the eyepiece spacing can be easily adjusted using a precision Siedentopf mechanism. The ocular tubes are angled at 30° to comfortably accommodate a seated position without neck strain, and the head can be rotated 360° to be used from various positions.
Optics
This model includes four brightfield objective lenses and four phase-contrast objective lenses. The brightfield lenses provide a magnification range from 40X to 1000X when used with the standard 10X eyepieces, while the phase-contrast lenses provide a 100X to 1000X range. Additional 20X eyepieces are included to expand the maximum magnification to 2000X.

Specimen Stage
The 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides. The stage's low-position controls are conveniently placed near the coaxial focus knobs for a streamlined workflow. Examining specimen slides is intuitive and precise for users at any skill level. An adjustable height limit can be set to prevent damage to the lenses and specimens while focusing.
LED Illumination
The LED sub-stage lighting provides cool, energy-efficient illumination. The light-source is daylight balanced to produce natural colors for imaging. The Abbe light condenser has a high 1.25 numerical aperture for oil-immersion, and an iris diaphragm to optimize contrast and depth-of-field. The condenser holder uses rack-and-pinion height adjustment for precision control.
Phase Contrast
A phase-contrast kit is included with a 5-position turret condenser and 4 achromatic phase-contrast objective lenses. Phase contrast is used to reveal detail in indistinct objects, such as unstained cells and microorganisms that would otherwise appear invisible. By using a combination of specialized objective lenses and a modified light condenser, these invisible objects can be visualized by manipulating variations in phase. This turret condenser allows you to easily rotate through the brightfield and four phase-contrast settings (10X, 20X, 40X, 100X). Each phase-contrast setting has a centerable annulus for proper alignment. Each of the phase-ring equipped objective lenses has achromatic corrections for improved color and resolution.
