Since 2003, the folks at Northern Focus Optical have been providing its customers within Alaska, Montana, northern Wyoming, and select remote facilities with expert microscopy service & repair. Since 2007, Jim Janoso, Northern Focus Optical’s Sales & Service Manager, has also been the microscope service technician for the U.S. Antarctic Program. References are available from within university and hospital systems, geophysical institutions, federal & state government laboratories, military bases, and private industry research laboratories.

The following table gives a detailed description of what customers can expect from our preventive maintenance service.

Repair services are also available for issues beyond normal preventive maintenance.

Preventive maintenance and repair services are available for centrifuges, autoclaves, cryostats, microtomes, and slit lamps as well.
