TechSpec™ family of light pipe homogenizing rods

BARRINGTON, N.J. - Edmund Optics (EO) announces the release of the TechSpec™ family of light pipe homogenizing rods for OEM illumination needs. The rods use total internal reflection to turn a non-uniform light source into uniform illumination and deliver it to the target site. These rods are ideal for applications where point sources such as LEDs must be combined and made to deliver even lighting.

Unlike traditional square integrating rods, TechSpec™ rods have a hexagonal cross section. The hexagonal shape provides a better match to spherical point source wave fronts, resulting in a 35% increase in coupling efficiency, allowing these light pipes to deliver brighter illumination for a given light source.

Also known as integrating rods, light pipes utilize total internal reflection to effectively randomize entrance angles at their output aperture. The result is a homogenization of the original light source's spatial intensity distribution, providing greater uniformity of illumination at the rod's end.

Because the homogenizing effects of traveling through the rod are not wavelength or entry-angle dependent, the rods can mix the light from multiple sources into a uniform beam. This allows OEMs to use the rods to combine the light from several LEDs to increase illumination intensity or to mix colors to obtain unusual spectral characteristics.

Price and Availability

TechSpec™ Homogenizing Rods are available in 2mm, 5mm, and 10 mm apertures and have lengths approximately 12x the aperture size. Prices range from $60 to $85, and all options are available for immediate delivery. Custom configurations are also available for OEM applications.
