Schott A20990 MC-LS LED Fiber-Optic Illuminator sets a new affordable standard for LED illumination for Stereo Microscopy and Machine Vision. The Schott MC-LS carries on the ACE 150-watt halogen illuminator legacy, the industry standard since its introduction.

The new Schott LED MC-LS is a cost-effective and reliable cold light source that delivers exceptional light output from the high-intensity LED light engine—developed from the ground up specifically for Stereo Microscopy, Macroscopy, and Machine Vision applications. The A20990 is a fresh design with a smaller footprint by 50% compared to the ACE A20500.

The powerful LED is temperature-controlled and features an ultra-quiet integrated fan for near-silent operation. It is also rated for 50,000 hours of operation. The engineers at Schott designed the unit to be energy-friendly, consuming only 60w of power while still managing to increase Light output to 850 Lumens, a 10% improvement in intensity from the older ACE A20500.

The LED Light engine is color-balanced at a consistent 5400k and eliminates the need to continuously white balance when using a digital camera for image acquisition.  The MC-LS features a convenient USB port and RS232, so the unit can be digitally controlled with any software that allows serial communication.

Schott has committed to backward compatibility with legacy equipment, and therefore, all existing fiber optics light guides such as goosenecks, ring lights, backlights, and line lines from the ColdVision series will plug right in with no adapter, making the transition from Halogen ACE or DCR light sources simple.

I really appreciate the level of personalized support Empire Optics offers. No matter what the issue is, we get help immediately.


We spoke with Nick and the Digital Microscope he suggested is working great. It is super easy to operate and checks all our boxes.


Working with Empire Optics to upgrade our Fluorescence microscope was a great experience. They were extremely attentive, and we are incredibly happy with the outcome.
