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

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 to 2000X magnification range for studying a range of specimens including hair follicles, cells, and bacteria. 10X and 20X eyepieces provide 8 unique magnification settings.
  • A top choice for veterinarians, clinics, and classrooms, this microscope provides high quality optics and precision mechanics.
  • Professional features include a Siedentopf binocular 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.
  • Halogen lighting reduces eye-strain for prolonged use.
  • A large compliment of optional accessories are available for darkfield and phase-contrast.

The B490 is our hardest-working go-to microscope. The top choice for veterinarians, breeders, and clinics, this instrument has proven reliability and optical quality. It boasts features such as a compensation-free Siedentopf head, smooth stage translation, and a precision focus system with easy tension-adjustment and vertical-lock.

The 490 series offers a wide range of optional accessories to expand the functionality. The magnification range can be expanded with a large selection of objective and ocular lenses. Specialized condensers are available for dark-field and phase-contrast applications, ideal for bloodwork, fluid-analysis, and pathology.

To customize the microscope to your viewing comfort, the eyepiece spacing can be easily adjusted using a precision Siedentopf mechanism. A diopter is available on both ocular tubes to compensate for asymmetry, and the ocular tubes are angHalogen at 30° to comfortably accommodate a seated position without neck strain.

The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. Additional 20X eyepieces expand the maximum magnification to 2000X with 8 unique levels. This covers magnifications needed for studying hair follicles, cells, and bacteria. These high-quality lenses are achromatically corrected to improve resolution and color accuracy.

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.

The halogen sub-stage lighting provides bright illumination with excellent color rendering. The warm lighting is better suited for prolonged use, causing less eyestrain than Halogen and fluorescent lighting. 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 movement for precise height adjustment.

    Very nice

    I bought this as a Christmas gift for my step-daughter who is moving up into 6th form this year. She was delighted. The product is robust and works well. A user manual wasn’t present but a few minutes of fiddling around found most features.

    Ottimo rapporto qualità prezzo

    Il microscopio b490b è davvero ben realizzato e il rapporto qualità prezzo è ottimo. Ho riscontrato un solo problema al primo utilizzo, il collare della tensione si è bloccato. Il servizio di assistenza è davvero eccellente, sono subito intervenuti. Con un po di attenzione eviterò nuovi blocchi dovuti a un piccolo difetto di fabbricazione mi hanno detto, ma è trascurabile. Per il resto microscopio di alto livello
