| Features:
- Ultra-portable: This ultra-portable is an excellent diagnostic instrument for the examination of anterior segment structures and ocular abnormalities. Its easy-to-operate optical system produces a high-brightness, continuously adjustable slit image ideal for pediatric and geriatric setting, emergency department screenings, ward rounds, beside examination, post-op evaluations, and mission work;
- LED illumination: the first and the only portable slit lamp in the world applying LED illumination system. The most prominent advantage of our LED illumination system gives the examiner the clearest image without glare;
- Comfortable using experience: The low heat radiation from our LED lamp makes the most comfortable examine experience for the patient;
- Sharpest Slit: With the blade imaging system S150 gives equally sharpest slit as the best classic slit lamp in the world;
- No need to replace illumination lamp: The LED lamp used in S150 portable slit lamp is rated 20,000 hours at full power. Its lifetime is almost 10 times longer than a normal halogen lamp;
- Power-saving: S150 can work for long hours without changing batteries.
Technical Specifications:
- Magnification: 5x
- Range of slit length: 5mm~11mm
- Minimum slit width: 0.2mm
- Working distance: 12~32mm
- Power supply: AA batteries x 2
- Illumination: LED blub(3.3V/1W)
- Battery life: More than 3h(AA alkaline batteries x 2)
- Net weight: 150g(without batteries)
How to Operate:
- Press the Power Switch to turn the slit lamp on/off
- Loosen the Locking Screw
- Twist the Lamp Body while holding the Magnifier Bracket still till the slit is in the required angle
- Push or pull the Lamp Body while holding the Magnifier Bracket still to set the Magnifier into a position comfortable for observation
- Fasten the Locking Screw
- Pull the Lamp Head back and forth for adjusting the width and the length of the slit, as well as the intensity of the light

| 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
