Descripción
Included power/ communication box
The Nidek phoropter RT-2100 is a computerized refractor used for subjective refraction when connected to the Nidek Auto refractometer (AR), Auto Ref/Keratometer (ARK) And Auto Lensmeter (LM). The operator has a fully integrated refraction system that simplifies and speeds up refraction.
Features
- Included power/ communication box
- High contrast LCD screen with full data display
- Lots of information is just a click away on your display with options to view pupil distance, previous lens data, refractor lens settings, unaided visual acuity, objective measurements, chart indications and full test data to name a few
- Simple dial operation
- Full program in 5 different sequences
- From unaided measurement to full prescription, you can set the RT2100 up exactly how you want
- Automatic VA value prediction
- Final Fit… Compute the most comfortable value automatically with extra refinement via semi auto adjustment
- Various interface functions to connect to external appliances
- All the masked charts are switchable for single letter masking
- Selectable dioptric steps
- Subjective refinement from selectable AR/LM data
- Selectable axis and prism steps
- Selectable automatic PRISM feeder speed
