A37 Series Ringlight

Dolan-Jenner's ring lights provide excellent uniformity, intense shadow-free on-axis lighting and are especially useful when imaging or inspecting highly reflective objects. This ring light Illumination Systems provide high intensity illumination at the highest magnification and long working distances without light adjustment when refocusing or when zoom features are used. The fiber optic system will eliminate the clutter and head radiation of multiple conventional Light sources.


Product Description

The A37 series fiber optic output is an annular (ring) configuration supplying 360 degrees of brilliant, oblique and even cross-illumination directed toward the optical axis at working distances from 1.5 to 9.0 inches (4-23cm). Fits objective lenses 50mm-60mm diameter.
