AmScope HL150-BY 150w Dual Gooseneck Fiber Optic Microscope Illuminator

Welcome to SCHOTT Microscopy. My name is Christian Zawar. Today, I would like to explain the difference between the two main techniques of illumination used in stereomicroscopy: On the one hand, fiber optic illumination and cold light sources such as our KL series, on the other hand, direct LED illumination as in our EasyLED and VisiLED series. Stereomicroscope illumination has its origin in fiber optic illumination. Back in 1960, in other words almost 60 years ago, SCHOTT introduced the first cold light source equipped with fiber optic light guides to the market. Over this long period of time, fiber optic illumination has established itself as the standard due to the many different light guides and its compatibility with all common stereomicroscopes. The light emitted by a cold light source is guided to the sample via glass fiber light guides. In the fiber itself, the li
