YZ24 Streak Retinoscope

This instrument is used for determination of the axis location of astigmastism and wrong dioptry.

YZ-6E Ophthalmoscope

This instrument is equipped with rotable dioptric lens disc providing 23 different degrees, and diagram disc(if rotating it, the light will form 5 different illumination spots in turn: big, small, red-free, central network dark spot and regular slit. It's perfect for various kinds of examinations.

YZ25A Binocular Indirect Ophthalmoscope

The halogen lamp brings even and bright light with stepless adjustable intensity. Made by high quality engineering plastic with good design, compact in structure and light in weight. Equipped with accessories including filters, teaching mirror and scleral depressor.

YZ 7A Tonometer

It measures the intraocular tension by registering the depth of indentation production produced in the cornea by a plunger carrying a known weight. Each division on the scale corresponds to an indentation of 1/20mm in the cornea.

YZ 30 Applanation Tonometer

This instrument is designed according to the principle of GOLDmanm Applanation Tonometer. It tests the eye pressure through testing certain corneal area(Diameter is 3.06mm) flatted by the testing head. Magnify 10x with the slit lamp to precisely measure the diameter of the flatted area. It is of high precision and the average error is less than ± 0.5mmHg. Eyepressure reads out directly in mmHg.

Specifications:
Range of measurement: 0-80mmHg
Light ring displacement: 1.53 x 2=3.06mm
Diameter of the testing head: 7mm
