Handheld Digital Auto-refractometer(AutoSight 900) is a portable vision screener for patients at any age. Its working principle is the refraction of light. Optical rays are focused on a sensor after passing through the eye's refractive system. The spherical power, cylindrical power, and axis of both eyes can be obtained by digital signal processing. Features of Handheld Digital Auto-refractometer:

Quick: Automatic and convenient. Press the button at the working distance (35cm/14in) and that's it. The result will be automatically shown in 5 seconds.
Accurate: Objective measurement of diopter is obtained from optical signal. The result is not affected by various external factors.
Intelligent: Detects multiple eye problems in one measurement including myopia, hyperopia, astigmatism and anisometropia

Technical Specifications of Handheld Digital Auto-refractometer:

Item		Range	Interval	Tolerance
Spherical (S)	Myopia Mode	-9.00D~ +2.50D	0.25D	±0.50D or ±20% (whichever is greater)
	Normal Mode	-6.00D ~ +8.00D
Cylindrical(C)		-3.00D~0.00D	0.25D	±0.50D or ±20% (whichever is greater)
Axis(A)		0°~180°	1°	±5°

Operation Microscope(YZ20P5) is a simple binocular coaxial microscope for a single man. The Microscope is small, light, and convenient. It has high agility and can meet the requirements for general ophthalmology operation. The microscope fits mobile medical treatment. Features of Operation Microscope:

Multi-layer coating technology is used on optical lenses to enhance the transmission rate and prevent mildew.
Foot-controlled focus, three-step magnification change, good depth of field of view, and good binocular fusion to meet the need of cataract surgery.
Using apochromatic technology to make different wavelengths of the light focus near the focal point behind the lens, so as to make the operator's vision more clearly.
The machine weighs only 41Kg to be light and compact and is especially applicable for mobile medical.
Optional desktop components to make the machine more portable and can also be customized according to special requirements to meet the needs in ophthalmology, ENT and other surgery.
