Wild Heerbrugg Illuminator


This modern LED illuminator replaces the old Wild Heerbrugg illuminator found on some older microscopes. The LED provides a much brighter, whiter light while consuming 90% less energy and generating 90% less heat. Eliminate bulb replacements and free up bench space. The unit is self-contained with no separate power adjustment box like the original. Full range intensity control from 0 to 100%.

If the illuminator port on your microscope has an ID of 26mm (1.02 inch) this illuminator will probably fit. Check the above pictures and the drawing in the link below for dimensions to compare with your microscope if you are not sure. If it does not fit you can return it.
