Schott 157.440 KL Series Maxi Ringlight 150mm

The Schott 157.440 Maxi Ringlight is the flagship large-format annular ring light in the Schott KL series — with a 150mm (5.9") inner diameter, it delivers homogeneous, shadow-free ring illumination over a working area that dwarfs the standard 66mm and 4" (102mm) ringlight formats. At this scale, the 157.440 is purpose-built for applications where the specimen, assembly, or imaging subject is simply too large for any standard ringlight to illuminate uniformly from all directions: large biological dissection specimens, wide-format industrial assemblies, macro photography of large objects, forensic document examination, and wide-field quality control inspection of large components. The annular ring design distributes light evenly from all directions simultaneously, eliminating directional shadows and hot spots across the full illuminated field regardless of specimen size. Compatible with Schott KL 1500, KL 1600, and KL 2500 cold light sources. Precision German fiber optic construction ensures consistent ring uniformity and long service life.
