6.According to the demands of the surgery, lighting spot size adjustable
7.Six degrees of freedom movement, to and fro and around large Angle electric pitch, rotating
8.The microcomputer control, the modular design, can teach, photographing, camera
9.Optional monocular teach mirror, digital photographic system and CCD camera system and expert operation video image processing system
10.Xenon lamp lighting, double bulbs conversion

The main functions and technical parameters：
1.Hand-held control a key start, comfortable and convenient.
2.Space electromagnetic lock positioning, the rotating joint control freely.
3.Binocular primary mirror with optical hinge, reversible 180 °, but six degree of freedom movement, or so before and after electric pitch range are greater than 100 °.
4.Ocular: 12.5 x, wide Angle, with diopter adjustment and limit device. Working distance: 200,250,300,350,400 mm.
5.Binocular vice mirror can be arbitrary Angle rotation, and with the main mirror synchronous (with light path, with ratio, with field).
6.Lord, the secondary are electric continuous stepless variable times, magnification: 5x-25x, image is clear, the depth of field is big, reflect feeling is strong, can meet all kinds of deep cavity the demands of the surgery.
7.The apparatus adopts xenon lamp coaxial cold light system, operation surface lighting 80000 to 180000 Lx, and double bulbs conversion.
8.Field diameter: 85.0 mm to 8.5 mm, and size spot adjustable. Suitable for deep cavity operation need.
9.The apparatus adopts electric trimming focal system.
Trimming focal range:40mm，Focus speed：1-2mm/s。
10.The apparatus adopts microcomputer program control, with stepless adjustable light, speed control system, and can be set up storage and a doctor of the conventional parameters. Switch using liquid crystal touch screen display design, the use of stable and reliable. The apparatus adopts foot landing gear, use agile and convenient, hold to stability.
11.Rack with streamline design, coarse adjustment lift range was 500 mm, arm exhibition was 1200 mm, bearing arm rotation Angle 360 °.

HONGKONG LIHUA ELECTRONIC TECHNOLOGY DEVELOPMENT CO., LIMITED is specialized in the production and sales of research experiments microcirculation， using SDF technology (sidestream darkfield imaging (SDF), sidestream dark field (SDF) imaging ), the observed changes in special parts of the animal and human blood. observe the special parts of the animal or human blood flow changes.
The condition of the blood vessels and blood of experimental animals can provide for the animal experiments, in order to cardiovascular disease in experimental animals blood poisoning、sepsis and failure early noninvasive monitoring and scientific data, and provide scientific data for the human disease.
Product: sublingual microcirculation (lingua microcirculation,tongue microcirculation, cerebral microcirculation, renal microcirculation ,visualize the microcirculation at the bedside and sidestream dark field (SDF) handheld imaging device (Microvascular (blood) image observation instrument) etc.
Its technical characteristics are as follows:
(1) Use SDF technology, can observe animal or person special parts such as the tongue, kidney and other parts of the blood flow changes.
(2)can provide the number of capillaries, vascular caliber and velocity, TVD / PVD, PPV, / MFI of experimental animals of data , and so on .
(3) equipment with convenience, can be carried out directly noninvasive observed in the laboratory experiments bedside characteristics, operation is simple.
