Exophthalmosometer

HEM300
Exophthalmos measurement range: 0 to 35 mm, with an accuracy of ±0.5 mm (half-division).
The graduation range of the left and right prisms is 0 to 35 mm. The red indicator line on the right angle should align with the graduation line with the measurement number "18" with an offset of no more than 0.5 mm (half-division).
The zero position on the graduation lines of the left and right prisms of the exophthalmometer should coincide with the lowest point of the frame arc with an offset of no more than 0.5 mm (half-division).

The HEM300 exophthalmometer uses the Hertel principle to measure the distance between the outer orbital rim (orbital wall) and the corneal apex. The meter utilizes two isosceles right-angled triangular optical glass prisms. The corneal apex and millimeter scale are simultaneously projected onto the prism surface through total internal reflection at an inclined surface. This allows for precise measurement of the height of the corneal apex protruding above the outer orbital rim.
