The big benefit of field microscopes is portability. They’re designed for professionals—like veterinarians, researchers and textile or currency inspectors—to slip into a pocket for a quick look at samples on-the-go. They’re also an ideal lightweight tool for transforming hikes or neighborhood walks into a field trip. Pocket microscopes have a small magnification range like 60X or 120X—making structures 60 or 120 times bigger—and a simple LED light to illuminate the specimen. For the best image quality, look for an aspherical lens, which ensures crisp on-the-trail viewing.
