OMAX 40X-2500X Phase Contrast Trinocular LED Compound Microscope+14MP Camera
Key Features
- 14MP (4096x3288 pixels) color digital camera with 0.5X reduction lens and 0.01mm calibration slide
- Phase contrast microscope for viewing live cell cycle, no staining required to view the slide
- Four phase contrast lenses and one bright field Abbe condenser on one disk, fast and easy to switch, no condenser change needed
- Large double layer mechanical stage and coaxial coarse and fine focus knobs
- Replaceable 3W LED transmitted light with adjustable intensity
The M837L series compound microscope is a class leader offering professional features at an affordable price. The trinocular viewing head is customizable and is equipped with a dedicated photo port which works simultaneously with both eyepieces. 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.
Viewing Head
The trinocular viewing head has a comfortable 45° incline for viewing while seated or standing, and can be swiveled 360°. Ocular spacing can be easily customized using sliding interpupillary adjustment. Dual diopters allow both eyepieces to be focused independently. The trinocular photo-port adds a dedicated mounting tube for cameras. The 23mm tube is height-adjustable to fine-tune the focus to match the eyepieces. Its simul-focal design allows simultaneous use with both eyepieces so no switching is necessary.
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 25X eyepieces are included to expand the maximum magnification to 2500X.
Objective Lenses
| Magnification | Corrections | NA | Immersion Medium | Cover-glass Thickness |
|---|---|---|---|---|
| Brightfield | ||||
| 4X | achromatic | 0.10 | — | 0.17mm |
| 10X | achromatic | 0.25 | — | 0.17mm |
| 40X | achromatic | 0.65 | — | 0.17mm |
| 100X | achromatic | 1.25 | oil | 0.17mm |
| Phase Contrast | ||||
| 10X | achromatic ph | 0.25 | — | 0.17mm |
| 20X | achromatic ph | 0.40 | — | 0.17mm |
| 40X | achromatic ph | 0.65 | — | 0.17mm |
| 100X | achromatic ph | 1.25 | oil | 0.17mm |
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. A convenient lever grouped with the left-side focus knobs can be used to lock and unlock the coarse focus adjustment to prevent damage to the lenses and specimen.
LED Illumination
The LED sub-stage lighting provides cool, energy-efficient illumination. The light-source is daylight balanced to produce natural colors. 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.
A sub-stage mirror is included as an alternate light source when electricity is not available. The mirror can be mounted on top of the illuminator’s field lens to direct ambient light into the condenser.
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.
Digital Imaging
The included 14MP camera and software allow you to preview and record photos and videos on your computer. The camera attaches to your computer using a simple USB 2.0 connection. Our professional software for Windows provides a wide assortment of capture and photo-editing functions including color correction, time-lapse capture, and a full complement of measuring tools. Cutting-edge features such as real-time auto-stitching and focus-stacking add new dimensions to imaging. A lite version of our software is available for Mac and Linux with essential functionality for capturing photos and videos.
