Description
What’s Included
- Reichert 11635B Plus Cylinder Phoroptor
- 90-day Digital Eye Center warranty
Condition & Warranty
Used. This unit has been fully tested, cleaned, and mechanically serviced so the lens wheels rotate smoothly, the synchronized axis gears track accurately, and every detent has a crisp, positive click. The optical paths are clear and the chassis shows only minor cosmetic wear consistent with a used manual refractor. Covered by a 90-day warranty on parts and workmanship.
Reichert 11635B Phoroptor — Used Manual Refractor with Plus-Cylinder Optics
The Reichert 11635B Ultramatic RX Master Phoroptor is a manual ophthalmic refracting instrument used to determine refractive errors and refine prescriptions for corrective lenses. Its plus-cylinder configuration allows clinicians to evaluate sphere power, cylinder power, and cylinder axis during subjective refraction.The instrument features mechanically controlled lens selection, a cylinder-axis adjustment system, a rotary prism mechanism, and an auxiliary lens dial for additional examination procedures. Its manual design does not require an electronic power supply for routine operation.The 11635B is intended for clinical refraction workflows in which the practitioner changes lens powers and evaluates the patient’s visual responses to determine the appropriate refractive correction.
Why Practices Choose the Reichert 11635B Phoroptor
- Plus-Cylinder Refracting System — Supports subjective refraction using a plus-cylinder lens configuration.
- Wide Sphere Range — Provides spherical powers from −19.00 D to +16.75 D in 0.25 D increments.
- Cylinder Power Adjustment — Allows cylinder measurements from 0.00 D to 6.00 D in 0.25 D increments.
- Rotary Prism Mechanism — Supports prism adjustment for binocular vision and ocular alignment assessments.
- Auxiliary Lens Dial — Provides additional lens options and open apertures for specialized refraction procedures.
- Manual Operation — Uses mechanical controls without requiring an electronic power supply or software.
- Established Clinical Design — Suitable for routine subjective refraction in optometry and ophthalmology practices.
Clinical Applications
- Subjective Refraction — Determining refractive prescriptions for eyeglasses.
- Myopia and Hyperopia Assessment — Refining spherical lens power.
