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

  • Explore the Hall Effect in a GaAs semiconductor
  • Investigate systematic errors and their elimination
  • Determine the conductivity of the semiconductor
  • Use semiconductor to plot coils’ magnetic field

€¢ Explores the Hall Effect in a GaAs semiconductor

€¢ Explores systematic errors and their elimination

€¢ Determines the conductivity of the semiconductor

€¢ Uses the semiconductor to plot the coils€™ magnetic field

The Hall Effect is the generation of a side-to-side voltage in a conductor or semiconductor carrying a current when it is placed in a magnetic field. The effect is widely used in magnetic field sensors. It is associated with several well-known systematic errors, some of which can be eliminated by special measurement techniques.

This Hall Effect Apparatus consists of a mounted n-type semiconductor chip on a traverse mechanism, a pair of coils, relay-controlled reversing switches, and a control unit with connecting cords.

Features:

€¢ n-type GaAs Hall sensor chip

€¢ Helmholtz coil pair 75mm effective diameter, 11.25mT central mag-netic induction at 0.5A

€¢ Two-axis mechanical traverse for field plotting

€¢ Constant current sources for magnet (0-0.5A) and Hall driving current (0€”3mA)

€¢ Reversing switch for exploring the elimination of systematic error

€¢ 3-1/2 digit current and voltage meters

€¢ Metal storage case for the Hall Effect board
