Key facts

• Sphere measurement increment Refractometer
• Sphere measurement increment
• Sphere measurement increment is the specificity to which a refractometer can measure the sphere diopter, typically 0.25 diopters, but may be as small as 0.01 diopters. For example, a 0.25 diopter increment allows measurement of 0.25, 0.5, 0.75, 1.0 diopters, etc., while a 0.01 diopter increment allows finer measurement to a hundredth of a diopter.
