The M620C-R monocular compound microscope sports a new design and updated quality-of-life features such as dual power with Universal USB-C to USB and included AA rechargeable batteries! It is designed for teaching demonstrations, clinical examinations, and laboratory applications. An ideal microscope for teachers and students, including those in medical school or with a major in biology. It has a number of advancements in functionality compared to other microscopes in its class, such as enhanced LED lighting, and a centerable condenser. Use the microscope for studying fixed or live cells, bacteria, plants and soil, or water samples. USB-C Rechargeable & Portable A USB-C to USB-A cable and three rechargeable AA batteries are included, giving more options for how and where you are able to use your microscope. The low power consumption allows you to plug into any USB port such as a wall adapter, laptop/PC, or power bank to power the LED illuminator and simultaneously charge the batteries. This makes it the perfect microscope for large classrooms where power outlets are limited or for field research and mobile labs. The USB-C cable should only be plugged into the microscope when rechargeable batteries or no batteries are installed. Never plug in power when alkaline AA batteries are installed. Viewing Head This mode uses a simplified viewing head with a single ocular port. Various eyepieces can be used to increase the overall optical magnification. Optics The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. Additional 25X eyepieces expand the maximum magnification to 2500X with 6 unique levels. This covers magnifications needed for studying hair follicles, cells, and bacteria. These high-quality lenses are achromatically corrected to improve resolution and color accuracy. The Stage The 3-layer mechanical stage provides smooth and precise movement for examination of specimen slides. The stage's low-position controls are conveniently placed near the coaxial focus knobs for a streamlined workflow. Examining specimen slides is intuitive and precise for users at any skill level. Transmitted Illumination The LED sub-stage lighting provides cool, energy-efficient illumination. The light-source is daylight balanced to produce natural colors for imaging. With our specially developed fly-eye lens, the light is evenly distributed at maximum brightness to improve contrast and resolution. Illumination is further enhanced by a centerable Abbe condenser, which can be realigned for any magnification to guarantee proper lighting.
