Cold light sources KL5120-2

The KL5120-2 model is a steplessly variable cold light source without color change with a long-life halogen reflector. This cold light source offers excellent transmission of white light while maintaining the color range. The mains voltage can be set automatically between 110-230 V. Various light guides are available: one or two-armed and with rigid or flexible extension.

The cold light sources have fiber optics. This is an optical component consisting of many glass fibers arranged in parallel as light guides that are fused together to form a mechanically homogeneous block. They are also known as fiber optics.
Light can propagate virtually unhindered in the fiber direction in glass fibers. both of which are made of dielectric materials. Optical fibers are used in many areas where powerful direct illumination by optical fibers is required. The KL5120-2 model is ideal for microscopic incident light illumination or for use in microscope photography and many assembly tasks.
