西德LEYBOLD-HERAEUS高真空技术公司研究与生产一种名叫“LAMABS”的激光测量台,用于测定光学膜层的吸收与散射,其测量精度已达到吸收率A=士0.01％,散射率S=±1×10~(-5)。测量台的测量原理如下: ①吸收测量原理: 被测量样品用足够功率的氩离子激光器(输出功率约为1瓦)照射后,对由于吸收而产生的温升进行测量,就可直接测得介质反射镜的吸收。温升可用电阻温度计
West Germany LEYBOLD-HERAEUS high vacuum technology company to study and produce a called “LAMABS” laser measuring station for the determination of optical film absorption and scattering, the measurement accuracy has reached the absorption rate A = ± 0.01%, the scattering rate S = ± 1 × 10 ~ (-5). The measurement principle of the measuring platform is as follows: ① Absorption measurement principle: Measured sample After the sample is irradiated with argon ion laser with enough power (output power is about 1 watt), the temperature rise caused by absorption can be directly measured The absorption of the mirror.
