G250 Series – Powerful White Table Top / Pole Mount


The G250 is the brightest light guide illuminator ScopeLED offers. It is designed to meet the high light output demands of macro zoom as well as life science and industrial microscopy applications. We have engineered even more LED chips into our Dense Matrix LED™ Array to maximize light output while still maintaining the compact and economical design that is characteristic of all ScopeLED products. These densely organized LEDs couple light efficiently into more intensity than that of a standard QH-150W EKE halogen illuminator. And with more than 30,000 hours of LED lifetime regardless of intensity, it will last many times longer. The G250 Series is offered with either a manual intensity knob or 0-6VDC intensity input and in either a table top or pole mount configuration. These models accept most existing light guides, which can be readily incorporated into your system.

Whether your application is biomedical or physical science examination, device inspection, long working distance testing, or assembly, the ScopeLED G250 illuminator will provide the reliable and bright light you need, and in the compact form you want. Furthermore, if your application requires colors or correlated color temperature (CCTs) that are not covered by our standard models, simply contact us and we will be happy to work with you on a custom built color G250. ScopeLED provides optional light guides and ring lights for a complete illumination system.

Applications include machine vision, visual inspection, forensics, biology, and microscopy.
