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

  • 2 levels of stereo magnification from 20X to 40X
  • A halogen top-light provides incident illumination for opaque objects.
  • The compact design is perfect for students and hobbyists with limited space.
  • The pillar stand provides more flexibility to position the microscope head, including adjusting the height.

The SE304R-P is an ultra-compact stereo microscope designed primarily for students and hobbyists. The microscope is equipped with two pairs of high-quality objective lenses, and can use various eyepieces for multiple levels of magnification. This simplicity and versatility has made it popular among coin collectors and engravers. Younger users will find the instrument easy to use thanks to the modest magnification range, and the stereo optics which provide three-dimensional viewing and upright images. The forward-oriented head places the observation stage closer to the user which is typically beneficial for delicate work using soldering or cutting instruments. The microscope uses a pillar for height-adjustment, allowing free vertical and rotational adjustment. A single light-source is mounted above the stage to provide the necessary illumination for observing opaque objects.

Two pairs of objective lenses provide 20X and 40X stereo magnification when used with the included 10X eyepieces. This range is intended for common soldering and mechanical repair, and inspecting larger objects. The objective magnification can be changed by simply rotating the nosecone to switch lenses. The viewing head uses 30.5mm ocular tubes to provide an extra-large field-of-view. One ocular tube has an integrated dioptric adjuster for users with astigmatism, or to fine-tune focus when using a camera in place of the eyepiece. The head can be adjusted for any user using rotating binocular adjustment to guarantee proper alignment with the eyes. Various eyepieces are available to expand the magnification range.

Focus can be adjusted by using symmetrical knobs for fine adjustments, or more coarsely by vertically sliding the head along the pillar. The pillar also allows rotation for lateral adjustment, and can accommodate a slightly larger working distance compared to the track-stand model thanks to this free adjustment. Tension in the focus knobs can be adjusted using an included spanner wrench, ensuring comfortable use.

An incandescent lamp is mounted to the focus block, providing built-in illumination. This reflected lighting can be used for opaque and semi-opaque objects. The warm halogen light is easy on the eyes, and produces a full spectrum for accurate color reproduction.

The microscope’s stage uses a simple design with a reversible plate and two stage-clips. The stage-plate has a white side and a black side for selectable contrast when viewing light or dark objects. The stage-clips can be used to hold smaller objects in place by pinning them to the stage or restricting lateral movement.
