optical parameters

3.1 optical system between the magnification difference is not more than 1.5%.

3.2 optical system between the field consistency: things mirror in-plane vertical migration quantity is not more than 0.2 mm, horizontal offset no greater than 0.4 mm.

3.3 or so between the optical system of the focal length difference is not more than 5 mm.

3.4 the highest times field resolution not less than 63 line/mm.

3.5 or so between the field like inclined not greater than 2 °.

3.6 optical system exit pupil height difference set visibility moment value in the 0 bit not more than 1.5 mm.

3.7 distance minimum adjusting range 55-75 mm.

3.8 visibility minimum adjusting range + 5 - - 5 m - 1.

3.10 object surface spot center illumination not less than 15000 lx.

 

4, mechanical properties

Micro lift range not less than 35 mm.

Each activity joint operation should be smooth and flexible, accurate positioning, Lock the stable and reliable, and can not have jitter, automatic sink or card hysteresis. Frame in any position should be in good balance.

5, electrical properties

Safety category: I kind of equipment. Single-phase network power supply: 220 v, 50 hz.

Input power 220 va, fuse capacity of 1.5 A x 2, A multiply one.

5.1 surgery microscope work when the noise is not more than 65 db.

5.2 protective grounding impedance of not more than 0.2 Ω.

5.3 normal operating temperature of the earth leakage of not more than 0.5 mA, a single fault condition should be not more than 1 mA

5.4 normal working temperature dielectric strength:

A) network power section and has protective earthing shell parts should be able to withstand between 50 hz and 1500 v sine wave test voltage 1 min, no breakdown and flashover phenomenon (a - al);

B) intermediate circuit (transformer secondary 21 v winding and shell between) should be able to withstand 50 hz and 500 v sine wave test voltage 1 min, no breakdown and flashover phenomenon (A - al).

5.5 foot switch used in the operating , room with prevention into liquid requirements.

5.6 the technical description and specification merger. Users to repair if need relevant technical data, can all alone to manufacturer line take.

5.7 this equipment no electromagnetic, compatibility special requirements, portable and mobile RF communication equipment had no effect on this equipment. This equipment without source and electrostatic put power supply, this system for attachment within the increase and change will not lead to the increase of the launching equipment and immunity to reduce. The equipment should not and other equipment close or layers use, if you must close or layers use, should be observed verification in the use of the configuration can be normal operation),. Three, installation

1, open the packing container, check whether conform to physical and packing list.

2, first will stand for good, will microscope, lens (the Lord, deputy microscope) take out, it will be on the left a shaft insertion bending plate of the bottom of hole, and the hand wheel binding, again will screw admiral shaft and bending plate binding, and the last in the after electrify check each function is normal use, such as no problems can be pushed into the operating room to use.
