The controller allows for any of the four segments (10 LEDs each) to be turned on/off individually for added lighting flexibility. The ProLine 40 LED ring light systems have a universal power supply for worldwide operation. They can be custom configured to be powered by battery for field operation (please contact us for information).

The ProLine 40 ring light can be custom configured with alternate spectrum LEDs (e.g., Red, IR, UV, warm white), non-segmented versions, ESD safe models, or wide angle LEDs with quick delivery and no minimum quantity. Contact us with your specific requirements.

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.
