AmScope M500B-MS-LED Monocular Compound Microscope  

Cordless and Versatile

** Cordless Monocular Compound Microscope, WF10x and WF20x Eyepieces, 40x-2000x Magnification, Anti-Mold Optics, LED Illumination, Brightfield, Abbe Condenser, Coarse and Fine Focus, Plain Stage with Mechanical Specimen Holder, 110V or Battery


The AmScope M500B-MS-LED monocular compound microscope that comes with eight levels of magnification and precise widefield glass optical system. It is a cordless LED microscope that can be used both indoors and outdoors depending on the needs of the users.

The microscope also comes with a durable metal framework, which enhances stability as well as separate course and fine adjustment knobs. It also comes with interchangeable WF10x and WF20x eyepieces and a mechanical stage on which the specimen is held in place by a pair of clips. 

This particular microscope has been designed for students and kids. As such, it can be used in class or at home to teach students about microscopy.

Major feature of the AmScope M500B-MS-LED include:

  • LED with rheostat
  • 10x, 20x, 40xS, 100xS (oil) DIN achromatic (20mm) lenses
  • Single-layer Mechanical Stage
  • 10x widefield and 20x widefield eyepieces
  • DIN achromatic objectives


Being a high power cordless LED monocular microscope, the AmScope M500B-MS-LED is a versatile instrument that comes with a rechargeable battery operated system. As such, it can be used indoors (class, laboratory etc) as well as out in the field.

For kids, this is a great aspect given that they can take the microscope outside and are able to view a wide range of specimen.  The microscope also comes with interchangeable 10x widefield and 20x widefield eyepieces, which means that users can exchange the eyepieces depending on the specimen they are viewing.

The four objectives in place are DIN achromatic objectives, which provide color collection for magnified images. This allows for sharp, clear images when observing the specimen. The microscope also has an anti-mold head, which is an important aspect of the instrument in that it preserves the optics during high-humidity seasons and in high-humidity areas.

For increased safety of the objectives, the high magnification objectives have in place a spring system that allows the lenses to retract whenever they come in contact with the slide. Moreover, there is a stop system that users can use to set how far up the stage can go, thereby preventing it from going too far.

The lower (diascopic) brightfield illumination in place enhances visibility of both translucent and transparent objects. This illumination system allows the specimen to absorb light, which results in dark image on a light background. Using the rheostat controls in place, the user can also control the amount of light from the lamp (LED) to the desired amount of light required for different specimen. 

** If you were to use incandescent bulbs in this microscope (which is an option when purchasing) take note that they are the least expensive type of microscope bulbs and provide a steady source of light required for viewing the specimen. Although this light source has several benefits, it also has a number of disadvantages

Some of the other aspects of the AmScope M500B-MS include:

  • AC adapter/recharger for wall outlet for traditional power supply
  • 45 degree inclined 360 degree rotatable monocular head
  • A Mechanical stage for easy slide gliding control
  • Upward stage stopper to protect slides and objectives
  • Rugged metal frame with stain resistant enamel finish

AmScope M500B-MS-LED Pros and Cons


  • It is easy to use, and kids can use it with little supervision
  • Crisp clear images
  • As a rechargeable instrument, it is versatile and can be used outdoors



  • If you decide on the slightly cheaper model of this microscope with the tungsten bulb just be aware that it tends to generate quite a bit of heat, which can dry out and kill live specimen – this may make it frustrating to observe some live specimen, and the yellowish light produced by the tungsten bulb can affect colour accuracy.
  • At 2000x, images are not crisp


The AmScope M500B-MS-LED Monocular Compound Microscope is a good microscope especially for students. Although it does not produce the best images at very high magnification, it produces very clear images of the specimen at lower level of magnification (below 1000x).

It also comes with excellent features such as tension control that allow the user to be in control and made adjustments to get the best viewing experience. In addition, it is easy to use and will is a great way to introduce kids/students to microscopy.
