RL-9 LED Ring Light with Polarizer
Oct 2006
Orled (See Sensoray)Request Info
PORTLAND, Ore., Oct. 13, 20006 -- Orled, a maker of microscope ring lights and LED roadside lights, introduces the RL-9 LED Ring light with a polarizing option for inspection microscopes.

The RL-9, a high output LED ring light, now comes with a polarizing option that diminishes glare from reflective objects. It functions by allowing light from OrledRingLight.jpgthe RL-9's LEDs to pass through a polarizing film before illuminating the object. Light bounces off the object and passes through an analyzer before arriving at the eye of the operator or the lens of the camera. Rotating the ring at the center of the ring light aligns the analyzer with the polarizer. The result is an image that has less glare and more contrast.

Glare reduction can be an indispensable asset for many applications such as: in electronics, eliminating reflections off solder beads when inspecting assembled circuit boards; in dentistry, decreasing glare off wet enamel to allow cracks and cavities to be seen; and in plastics, rendering visible microfissures that would normally be hidden by surface reflections.

The single piece price is $615; quantity discounts are available. For more information, visit:; e-mail:

An instrument consisting essentially of a tube 160 mm long, with an objective lens at the distant end and an eyepiece at the near end. The objective forms a real aerial image of the object in the focal plane of the eyepiece where it is observed by the eye. The overall magnifying power is equal to the linear magnification of the objective multiplied by the magnifying power of the eyepiece. The eyepiece can be replaced by a film to photograph the primary image, or a positive or negative relay...
An optical device capable of transforming unpolarized or natural light into polarized light, usually by selective transmission of polarized rays.
