Dolan Jenner Dual Gooseneck Fiber-Optic Light Guide

The dual arm "gooseneck" systems offer exceptional versatility, combining compact design, low noise, and a powerful 40,000 ft. candles of focused illumination using LH759 lenses at a 3-inch (7.6cm) working distance when combined with the MI-150 or MI-LED Fiber-Optic light sources. The use of opposed angle illumination ensures a well-lit field with minimal shadow obstruction.

A highly sought-after choice is the EEG 2823M self-supporting bifurcated light guide, featuring a 0.28-inch (7mm) bundle diameter. Starting from the light source with a 45-degree transition incline, the gooseneck branches diverge at an angle suitable for accommodating any stereo microscope without interfering with focusing or specimen manipulation. Each branch boasts a 0.20-inch (5mm) bundle diameter. This system ensures precise light output placement, accommodating critical illumination requirements at various angles of incidence, from near vertical to near horizontal. The LH759 lenses can be easily adjusted or removed for diffuse illumination.

In laboratory settings, our dual arm gooseneck fiber optic assembly serves as an excellent ancillary light source for small animal microsurgery with a stereo microscope, general specimen preparation, examination of cultures, and tissue trim preparation for light and electron microscopy. Notably, it aids in minimizing morphological changes induced by dehydration and heat.

The EEG is offered in three different lengths, (18", 23" and 30") which are a direct for for the MI-LED and MI-150 B-Nose Fiber-Optic Light sources. If you have a different Fiber-Optic light source illuminator and are unsure if the EEG2823 will fit, please contact us for assistance. We can help you identify the correct components or adapters necessary so everything fits perfectly.
