The Bioptechs Objective Heater is a system specifically designed to safely and accurately warm the objective of a microscope to prevent heat loss from the specimen when using immersion lenses.  There are two main components,  are the electronic controller and the objective heating attachment.

The Bioptechs Objective Heater System is the only objective heating system that incorporates the thermal profile of the objective into the temperature control loop and regulates the objective temperature to the specimen plane where it belongs!
