Schott 157.440 KL Series Maxi Ringlight 150mm

The Schott 157.440 KL Series Maxi Ringlight (150mm) is the largest-format annular fiber optic ring light in the Schott KL series range — delivering homogeneous, shadow-free ring illumination over a 150mm (5.9") inner diameter for wide-field stereo microscopy, large specimen inspection, macro imaging, and any application requiring uniform ring illumination over an exceptionally large field that standard 66mm or 4" ringlights cannot cover.

• 📏 150mm (5.9") inner diameter — the largest KL series ringlight, providing ring illumination coverage far beyond the standard 66mm and 4" (102mm) formats
• 💡 Annular ring illumination for homogeneous, shadow-free lighting around the full 150mm circumference — ideal for large specimens, assemblies, and wide-field macro imaging
• 🔌 Compatible with Schott KL series cold light sources — KL 1500, KL 1600, and KL 2500 — via standard fiber optic light guide connection
• 🌟 Exceptional working area coverage — illuminates large biological specimens, industrial assemblies, documents, and macro photography subjects that no standard ringlight can cover
• 🇩🇪 Schott quality, made in Germany — precision fiber optic construction for consistent, high-efficiency light transmission and long service life
• ✅ New — catalog number 157.440

🔧 Product Description

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.
