PJ—1光电光楔测角仪是利用干涉原理直接测量光线通过光楔时产生的偏向角,而不必通过测量光楔的楔形角和折射率间接地计算出偏向角,因而避免了折射率测量误差的影响,提高了测量精度。同时,由于本仪器采用光电动态对准和激光测长、电子数显等先进技术,操作方便,测量迅速,从而大大避免了测量环境波动的影响,测量结果稳定。最大测角误差为0″.1。
PJ-1 photoelectric wedge goniometer is the use of interference principle directly measure the deflection angle of light generated by the optical wedge, without measuring wedge angle and refractive index indirectly calculate the deflection angle, thus avoiding the refractive index measurement The impact of errors, improve the measurement accuracy. At the same time, as the instrument uses photoelectric dynamic alignment and laser length measurement, electronic digital display and other advanced technology, easy operation, rapid measurement, thus greatly avoiding the impact of measurement environment fluctuations, the measurement results are stable. The maximum angular error is 0 ".1.
