Understanding this equipment family

The listed refractors belong to subjective refraction. The project concerns an examination station and its components: distinguish the head, control panel and interfaces when comparing a coherent configuration, rather than a single weight or range figure.

Questions to clarify before choosing

  • Which ranges apply to standard examination, and which depend on a particular mode?
  • Does the quotation include the head, controls and required boxes?
  • Are the requested prisms, test displays and interfaces included or optional?

Configuration and documentary limits

Documents distinguish components and variants. A head-only weight is not a system weight; prism functions and peripherals are not assumed to be supplied.

Documented differences between models

All three references document subjective refraction. The Refractor 900 record distinguishes the head, panel and central unit and qualifies prisms and peripherals; comparisons must therefore use the same component scope and variant rather than an inferred system weight.

The functions below are attached to a specific model and source. A function absent from this record is not declared unavailable: it remains unconfirmed here. Options and qualifications in the product records retain their meaning.
