YL50
YAG LASER
This apparatus is a kind of high precision, trauma-free, microsurgical equipment, which is composed of such four parts as Zeiss slit lamp microscope, Q toning Nd: YAG laser and power supply, semiconductor laser and power supply and control unit.
This apparatus uses superpower pulse Nd: YAG laser beam as treatment light whose wavelength is 1064mm, and whose pulse-width is compressed to nanoseconds. It uses two red color low power semiconductor laser beams as indicator light. When the two red light spots coincide, focal position is thus showed.
This apparatus is equipped with demonstration ophthalmoscope and camera system which can be used in consultation and medical history accumulation.
Performance index
Please refer to the manual of LDX type slit lamp microscope for its performance index. The performance indices of the laser system of this apparatus are as follows:
3.1. Treatment beam
3.1.1 Wavelength : 1064nm
3.1.2 Pulse-width: ﹤4ns
3.1.3 Mode: low level mode.
3.1.4 Pulse status: three kinds (serial 1 pulse status, serial 2 pulse status, serial 3 pulse status, which are optional).
3.1.5 Output pulse energy of the treatment apparatus (in front of eyes): ≧10mj-30mj.
3.1.6 Focusing aperture angle: 18°.
3.1.7 Focusing facula diameter: 50-100 um.
3.1.8 Output energy attenuates as per ten grades whose attenuation coefficients are respectively 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% and 100%.
3.2. Indicator beam:
Continuous output with the power of 1mw maximum can be continuously attenuated as required. It is aimed and positioned by double beam convergence mode.
3.3. Display:
The following four parameters are displayed digitally:
3.3.1 Pulse number of each action.
3.3.2 Single pulse energy.
3.3.3 Accumulated pulse number of each treatment.
3.3.4 Accumulated energy of each treatment.
3.4. Anti-wrong triggering measures:
There is lock switch in power source, standby precaution in display system, manual switches and so on. There are some protective measures for doctors operating the apparatus (The microscope has 1064mn total reflection lens).
