The annular ring design distributes light evenly from all directions simultaneously, eliminating the directional shadows that can obscure surface detail with single- or dual-arm light guides. This makes the 157.420 particularly well-suited for surface inspection, quality control, and imaging applications where consistent, glare-free illumination is critical. The 66mm inner diameter fits most stereo microscope objectives directly, and the standard fiber optic connection integrates with Schott KL 1500, KL 1600, and KL 2500 cold light sources. Precision German fiber optic construction ensures consistent light transmission and long service life.
