Who should buy it

The MM-300 is a simple optical field microscope for children, nature study, stamps and surface detail. It works without a phone, but the eye must be held close to the eyepiece and focus depth is shallow.

Before you order

  • Match the Carson MicroBrite Plus MM-300 model.
  • Expect observation rather than photo capture.
  • Begin at the lower power to find and center the specimen.
