A Digital Refractor is an important part of your practice, and we take their maintenance seriously. Every unit we clean gets the same thorough treatment. Our factory trained technicians disassemble the refractor unit, clean the bearings, races, and optical surfaces. We then re-lubricate, reassemble and align the instrument. In addition to the optics, we disassemble the yoke and clean and lubricate to ensure a secure connection to your stand. You can rest assured that your digital refractor, when maintained by proper technicians will last longer and maintain resale value.
