UP-OI35: The Köhler illumination upgrade package is for use with
any Multiscope™ model. The 6V/15W Halogen bulb is centerable and focusable via a high-performance collector lens system, built-in field diaphragm and a tiltable mirror. It includes an external, variable intensity power supply and a diffusing filter. This upgrade is recommended for light demanding applications, such as phase contrast and darkfield. Note: In order to install the Köhler illumination attachment, the current illuminator and its wiring must be removed. This is not a difficult procedure. For more information, please contact us!
