Schott 157.420 KL Series Annular Ringlight 66mm

The Schott 157.420 Annular Ringlight for KL Series (66mm) is a precision fiber optic ring light attachment designed for use with Schott KL series cold light sources — delivering homogeneous, shadow-free annular illumination around the optical axis for stereo microscopy, inspection, and precision imaging applications requiring even, glare-free surface lighting.

• 💡 Annular ring illumination for homogeneous, shadow-free lighting around the full circumference of the specimen — ideal for surface inspection and imaging
• 🔌 Designed for Schott KL series cold light sources — integrates directly with KL 1500, KL 1600, and KL 2500 illuminators via standard fiber optic light guide connection
• 📏 66mm inner diameter — fits most stereo microscope objectives directly
• 🇩🇪 Schott quality, made in Germany — precision fiber optic construction for consistent, high-efficiency light transmission and long service life
• ✅ New — catalog number 157.420

🔧 Product Description

The Schott 157.420 is an annular fiber optic ringlight attachment for Schott's KL series cold light sources, engineered to deliver uniform, shadow-free illumination around the full circumference of the optical axis. 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. Supplied new from stock, catalog number 157.420.
