This type lens tester is used to test the lens of the lens, the prism of the refraction, cylindrical axis, prism and prism baseline direction, and to the optical center of the lens, cylinder axis and cylinder base direction Print marks.

The instrument can be AC, DC dual (5 # 5 DC battery);

The instrument readings, scale clear, and intuitive high precision, good reliability, simple operation, easy to use.

And a compensating prism can correct the center of the spot, the lens and the mirror can be measured, is the glasses manufacturers, shops, ophthalmology ideal measuring instrument.
