[tab: Overview]
Problem: Your microscope is fine working condition, the optics are flawless, but illumination is either dim, brightness is not adjustable or bulbs are hard to come by.

Soultion: Retrofit your microscope with a high Power LED microscope illumination and these issues are in the past. Suddenly light consuming microscopy methods such as for example polarising or dark-field microscopy cease to be a problem. The utilised LED CREE XM-L is easily powerful enough for these tasks. The LED is powered with a  maximum of  1600 mA. At core of the  illumination solution is a LED driver and dimmer that I have specifically designed for this task. You can even make videos without any problems.

Custom made LED adapters are used for fitting the LED to your microscope. Upon request we can also do the conversion.

[tab: Universal LED Controller]
The Universal LED Controller is able to drive and dim all prevalent LEDs. Brightness may be controlled continuously between 0 and 100 %. Especially the new and powerful LEDs require fine adjustment if they are used in the bright field. To this end the universal LED controller was fitted with switch reduce the maximum power to 160mA, and thus adjusting the brightness in the bright-field is possible with ease. Of course this range may also be set to a different level by the user.

Further the controller features a set of six pre programmed maximum ratings to be able to drive LEDs other than 10W LEDs such as the CREE XM-L, without danger of destroying them.

The controller uses a softstart, i.e. there are no flashes during turning on the LED.
