Product Description
DJ6-E has the following characteristics:
1, the telescope uses the internal focusing system (J6E is the erect image focusing system), and the main mirror is three separate structures. The reticle is provided with double wires and monofilaments, which is easy to get different targets. Horizontal and vertical dividing wires have sight distance wires for distance measurement. The telescope has large aperture, high discrimination rate and clear imaging, and is suitable for observing near far targets.
2. The reading number of the disc uses an optical tape reading system. In the same field of view, the horizontal angle and the zenith distance can be read directly, and a lighting system is used. It is convenient to use, and the readings are fast and accurate.
3. A small telescope is used as a point device to observe the ground point. The object lens can be rotated with the alignment section; it is easy to find and eliminate the point error. The instrument also has a measuring hammer, which is easy to work on the point under different conditions.
4. The vertical shaft adopts a semi - motion shafting with spherical centring and ball bearings supported by a self centering spherical guide. It has high precision in orientation and alignment, is insensitive to temperature and is not easy to die. Because of the greater friction between the forced centering and the large spherical ball bearing, there is a slight "rustle" when running, but it will not affect the use.
5, the base is provided with an anti deflection spring. Through the reed, the upper and lower parts of the base are semi-rigid connections, which can prevent torsion and eliminate the lateral torsion error.
6. A tubular centering magnetic needle can be provided according to the requirements of the user.
7. The instruments were treated by environmental simulation test and mildew proofing and anti fogging before they were released. The instrument can work at the temperature of 25 °C to + 40°C
