Olympus BH-2 Top Illuminator (high power)


This LED illuminator replaces the original Olympus BH-2 Top illuminator. Provides a whiter, brighter light than the original, while consuming 90% less energy and generating 90% less heat. Problems with heat damaged bulb sockets, connector and power supply failure are all eliminated. No more bulb replacements. Problems with heat from the halogen bulb are eliminated, as are bulb changes. All the old components for the lighting system are replaced. Don’t buy a new microscope for thousands of dollars because of a bad illuminator. You can keep your perfectly good microscope working for a fraction of the price of an inferior new one. All Nanodyne illuminator systems include the power supply and required cables. Everything required for the illuminator is included. Your new Nanodyne illuminator will add decades of useful life to your microscope.

This light is three times as bright as the original Olympus BH-2 Top illuminator. If you found the original light to be drastically inadequate this is probably the one you want. If you found the original to be acceptably bright, or even somewhat inadequate, our standard unit will meet your needs at lower cost.
