The Higher the Magnification - The More Detail You'll See

Magnification 40x
Magnification 1000x
Magnification 2500x

Magnification is the ability of your microscope to make small objects seem larger. As the magnification increases the area being viewed will be decrease is size but the detail of the area being viewed will improve.

Amscope microscopes come with multiple magnifications to aid you in finding the proper magnification for viewing each specimen.

Camera Connection Types

When comparing 2.0 and 3.0 there are few major differences. First the transfer rates. USB 2.0 offers transfer rates of 480 Mbps and USB 3.0 offers transfer rates of 4.8 Gbps - that's 10 times faster.

Camera Resolution

The most important factor in ensuring successful microscopic imaging is choosing the appropriate optics and camera for your application that gives you more data and higher image quality. When selecting a microscope camera, it is best to base your decision on the most important requirements for your microscopic observation.

Key Features

  • Set of 2 Darkfield condensers for our 670 series compound microscopes
  • 100X Infinity-corrected Plan Achromatic Objective with Iris
  • Improve contrast in translucent specimens
  • Both dry and oil condensers for low and high magnifications

This is a darkfield condenser and objective set for our T670 microscopes. Both dry and oil condensers are included to cover a wide range of magnifications and numerical apertures. The dry condenser, with an NA of 0.7-0.9 is best-suited for lower-magnification objectives, typically up to 40X. The oil condenser has a maximum NA of 1.36, and is necessary for higher-magnification objectives. As well, the oil condenser will produce brighter highlights. A variable-aperture 100X objective is also included, to better control contrast at the highest magnification. Because darkfield uses oblique light explicitly, an objective lens’ numerical aperture must be significantly lower than that of the condenser to optimize contrast. The 100X lens’ built-in iris-control allows the NA to be fine-tuned for optimal results.

Darkfield microscopy uses principles of light-diffraction to suppress field-illumination, while illuminating the edges of otherwise-transparent or translucent objects through the use of oblique light. This is particularly useful for quantitative analysis of low-contrast specimens.
