Schott A20990 MC-LS LED Fiber Optic Light Source is a compact, high-performance illumination system designed for stereo microscopy, macro imaging, and machine vision. Built as the modern LED replacement for legacy halogen systems, the MC-LS delivers higher intensity, improved efficiency, and long-term reliability in a smaller footprint.

This unit provides up to 850 lumens of high-intensity output with a stable 5400K color temperature, eliminating the need for constant white balance adjustments when imaging. Designed for continuous use, the LED engine is rated for 50,000 hours and operates with low power consumption at just 60W.

The MC-LS maintains full compatibility with existing ColdVision fiber optic light guides, allowing seamless upgrades from older Schott halogen systems without requiring adapters.

This unit is fully compatible with Schott ColdVision fiber optic light guides and ColdVision flexible fiber optic bundles, making it easy to configure a complete illumination setup.
