Low Profile Ringlight


Product Overview

Dolan-Jenner's ring lighs provide excellent uniformity, intense shadow-free on-axis lighting and are especially useful when imaging or inspecting highly reflactive objects. The 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.

The LPA series fiber optic output is an annular 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 60mm-66mm diameter. Fits the most common setreo microscope objective diameters of 2" (50.8mm) through 2.6" (66mm).

To further reduce specular reflections from shiny surfaces, ring lights can be used in combination with a polarizer and analyzer.
