SELECTING A COMPOUND MICROSCOPE is as easy as 1-2-3...

Select the type of microscope you need or your industry

Select by type of microscope - Our Compound Microscope Assortment has been divided into major categories to make your shopping easy.

These categories include:

Brightfield, Darkfield, Phase-Contrast, Inverted and others

Choose a business application or industry to find the right compound microscope. Major industries or applicatins include:

Veterinary, Laboratory Use, Teaching, Metallurgical, Gemology and many others

Select a Magnification

AmScope offers an industry-leading selection of magnifications. All products are in-stock and usually ship the same day ordered

Select a Camera

We offer a wide variety of Cameras for every application - from student to professional use:

Select a type of camera - Eyepiece, USB 2.0 or USB 3.0 - to name the most popular choices

Choose the Megapixels of the camera - the higher the megapixel count on a camera sensor the greater the amount of detail that can be captured in an image

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 comaring 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

  • Large 8X-80X continuous zoom magnification range with standard 10X focusable eyepieces.
  • High-resolution Common Main Objective (CMO) stereo microscope for laboratory use
  • Infinity-corrected optics and parallel light-paths eliminate keystone distortion
  • Large 10:1 zoom ratio using 0.8X-8X continuous-zoom optics
  • Transmitted and reflected LED illumination for biological and industrial applications
  • Includes an inline phot-port module with a 23mm tube for use with reduction lenses

Our PM240 line of stereo microscopes takes advantage of the common-main-objective (CMO) optical design. Different from the more traditional models which use the Greenough design characterized by tilted objective lenses, CMO microscopes use a single objective lens which focuses light into two parallel optical paths. This results in some major advantages which include the removal of keystone distortion, and the ability to introduce intermediary optical systems without loss of image integrity. The modular design of the PM series allows for multiple configurations in which components can be added or replaced.

Standard Viewing Head

The standard viewing head keeps things simple. Elongated ocular tubes are mounted at a 20° angle, and allow viewing from a comfortable distance. Alignment with the eyes is done by using a sliding interpupillary adjuster. The tubes lack integrated diopters, so dioptric adjustments can be made by using focusable eyepieces when needed.


Optics

The zoom module provides a large 10:1 zoom range covering magnifications from 0.8X-8X. When used with the standard 1X objective and 10X eyepieces, the microscope produces images with stunning clarity at 8X-80X total magnification.

Infinity Optics

This microscope uses an infinity-corrected optical system which allows for a modular design in which accessories can be added without affecting magnification or image quality. Such accessories include photo ports and coaxial illumination systems.


Keystoning

By using a single objective lens and parallel optical paths, the CMO design avoids a type of distortion seen in other stereo microscopes called the keystone effect. Tilted objective lenses cause the independent images to be distorted in a manner where one side is larger than the other. This also causes gradual changes in focus and reduced depth-of-field. CMO microscopes do not suffer from this distortion, allowing for improved resolution and depth.


Dedicated Photo Port

This model includes an inline photo-port module which can be installed between the viewing head and zoom module. This adds a dedicated port for attaching a camera, avoiding the need to use one of the ocular tubes. The side-arm-style port uses a 23mm tube to accommodate a wide range of cameras with reduction lenses. When the port is switched open, it shares light with the viewing head, allowing use of all ports simultaneously. Closing the port allows all light to be passed through to the eyepieces for maximum brightness.


Support and Illumination

The dual-illumination stand provides a turnkey solution for biological and industrial applications. LEDs are used for the overhead and sub-stage light-sources, providing bright, low-heat illumination. Reflected and transmitted illumination allows for a wide gamut of specimens to be viewed. The track-style stand uses rack-and-pinion movement and large, coaxial coarse/fine control-knobs for precisely adjusting focus. The stage uses large 100mm circular plates for placing specimens. A transparent glass plate is included for use with the sub-stage transmitted illumination, allowing for a range of biological or other translucent specimens. A reversible black-white plate can be used when transmitted light is not needed, providing two options for enhancing specimen-contrast.
