Ophthalmic Mirror Exophthalmometer Corneal Protrusion Meter Optical Equipment

Featured

This instrument is used for precise exophthalmos measurements (e.g. exophthalmic goiter).  The basis of the measurement for exophthalmos determination using the Hertel version is the outer orbital rim (orbital wall) and the apex of the cornea.


Features
The product can precisely measure the level of exophthalmia over the orbital margins, on the principal basis that both vertexes of cornea and scaleplate are projected to the front of prism by total reflection on the bevel, with the special structure of the isosceles right-angled triangle prism.


Specifications
Measuring Range of the Exophthalmia: 0∼35mm
Adjustable Range of the Orbital Distance: 80∼120mm
