An upright microscope with first class optical performance at an affordable price.

The YS100 guarantees first class optical performance thanks to a combination of Nikon's excellent overall optical design, chromatic aberration free lenses, a prism-type eyepiece tube and 6V-20W halogen light source. Images are bright and needle-sharp right up to the periphery of the field of view. The durable design and modest price makes the YS100 ideal for education and routine laboratory use.
