一、实验条件照射光源:HJY-3型红宝石激光眼科治疗机,脉冲宽度0.7ms、发散度3mrad,输出能量≤2.5J,多模,光稳定度误差<3%.实验光路(见图):红宝石激光经(?)5mm限孔光阑射入改装后的裂隙灯系统,光束发散度为4.09mrad:再经装有浓度不同的硫酸铜溶液衰减杯,照射固定于五维调节架上的兔眼.用弱氩激光做同光路模拟照射,进行光路调整及确定照射部位.实时监测:对照射光束的稳定性经分束镜用R_j7200型能量计进行监测.入射兔眼的激光能量用另一台R_j7200型能量计进行测定.测量误差<±2%.实验时室温为17~22℃,相对湿度为75~80%.
First, the experimental conditions Irradiation light source: HJY-3 type ruby laser eye treatment machine, pulse width 0.7ms, divergence 3mrad, output energy ≤ 2.5J, multimode, light stability error <3% Ruby laser (?) 5mm aperture diaphragm into the modified slit lamp system, beam divergence of 4.09mrad: and then loaded with different concentrations of cupric sulfate solution decay cup, irradiation fixed on the five-dimensional adjustment rack rabbit Eye with weak argon laser to do the same light path simulation irradiation, the optical path adjustment and determine the irradiation site. Real-time monitoring: the stability of the radiation beam beamsplitter with R_j7200-type energy meter to monitor the laser energy into the rabbit eye laser with another Taiwan R_j7200-type energy meter were measured. Measurement error <± 2%. Experimental room temperature was 17 ~ 22 ℃, relative humidity of 75 ~ 80%.
