The Eclipse TS100 inverted microscope was introduced in 1999 to replace the wildly successful Nikon TMS microscope, which had been an industry staple for 17 years. The TS100 was a new generation microscope designed to incorporate the then new infinity optical system which allowed modules to be placed between the eyepiece and the objectives without changing the image. As microscopes were evolving, the TS100 also was the first time that ergonomics had been incorporated into the design. A more efficient, user friendly stage, and more comfortable focusing knobs together with infinity optics made this microscope capable of applications once reserved for higher end products.
The most current successor of the Eclipse TS100 is the Nikon Eclipse Ts2 inverted microscope.
