Elegant desing of butterfly shape apperance.
Capable of checking all-sided visual function, comfortable and precise measurments.
High graded plated-film used in all optic lenses.
The device is applicable to ophthalmology departments in hospitals and spectacle stores for precision measurment of visual functions such as:
-stereoscopic vision and eyesight amalgamation.
New Leveling Mechanism:
Reduce time leveing and adjusting the phoroptor.
Fingetip adjustment for Sphere Power Control:
With an innovative fast feed dial, rotating the knobs is effortless yet precise.
Fast Astigmatic testing:
Interlocking mechanism of the cross cylinder lens axis, will allow you to get a one touch accurate reading results.
Sanitary Face Shield:
New material technology coupled with ease of remove, to provide your patients a clean enviroment.
Precision Machined to finest Tolerances:
ERF-2600 employs top quality bearings, eliminating the need for periodic lubrication.
Sphere Power Range: +16.75D to -19.00D, minimum readings 0.25D or 0.12D (when +0.12D auxillary lens or optional +/- 0.12D lens is in use). +26.75D to -29.00D (when optional +/-10.00 lens is in use).
Cylinder Power Range: 0 to -6.00D with minimum readings 0.25D or 0.12D (when auxillary lens is in use) 0 to -8.00D (when -2.00D auxillary lens is in use). Astigmatic Axis Scale: 0-180 in 5 degree steps
Cross Cylinders: +/- 0.25D, reversal type (synchronized with astigmatic axis). Rotary Prism: 0 to 20D in 1 degree steps Interpupilary Adjustment: 48mm to 80mm in 1mm step (right and left synchronized)
Forehead rest adjustment: 16mm backward and forward
The optical axes of the lenses are aligned at a distance of 400mm from the vertexes of the corneas (2mm each for right and left inward) inpupillary distance enabling convergence = 57mm to 80mm.
Corneal distance device: 2mm forward and 5 mm backward from standard plane: with scale.
Effective field of view: 19mm plus cylinder.
