Seiler Instruments Westlab II Microscope

The Westlab II has all the features and more when compared to the original Westlab, such as reversed nosepiece for easier access to specimen slides. A Seidentoph binocular head that stays in focus when changing interpupillary distance. Semi-plan objectives instead of achromats which allow 90% or more of the field to be in focus at the same time.
