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

  • 40x-2000x eight widefield magnification settings with plan objectives
  • Simul-focal trinocular head boasts unique features
  • 23mm photo port for adding photo/video capability
  • C-mount adapter included
  • 3D two-layer mechanical stage with low position control

The T490B features a unique simul-focal optical system with an adjustable trinocular port to enable well-focused clear images on your computer or video screen while simultaneously obtaining sharp, focused images through the eyepieces. Most trinocular microscopes allow you to view either through the trinocular port or the eyepieces only, forcing you to switch between the two. Since these trinocular ports are not simul-focal with the rest of the microscope optical system, you have to re-focus the microscope after each switch. The T490B, however, erases this step by providing simul-focal viewing. Especially handy for teaching demonstrations, clinical examinations and laboratory applications, the simul-focal feature allows your students or colleagues to view clear images simultaneously while you work through the eyepieces. In addition, the T490B's industry standard 23mm photo port can be converted into a C-Mount port by attaching the included C-mount adapter, allowing you to attach most microscope digital cameras and video systems on the market. The T490B includes a 30-degree inclined 360-degree swiveling trinocular Siedentopf head, a 3-D mechanical stage, and an intensity-variable halogen illumination system. This versatile microscope is also capable of being upgraded with various accessories and attachments listed in the optional section for additional functions. It is a perfect laboratory instrument for clinics, Vets, Doctors, and professional students.

The T490B-PL features an extensive range of magnifications, from 40X to 2000X. The plan-achromatic lenses offer color-correction and an improved, flatter field-of-view, allowing for better edge-to-edge viewing with sharper details. The 490 series is compatible with a large array of optional accessories, including phase-contrast and dark-field kits, and a wide range of cameras.
