MPV型显微镜光度仪是利用光电效应测定样品反射率、透射率、折光率等多项光学常数的仪器.由于采用了不同波长的单色光,以及测量光阑与视域光阑联合使用,从而提高了测量精度.为保证测量值的准确性,减少或避免可能产生的误差,必须对仪器调节和操作过程中的关键环节给予足够重视.本文简要介绍该仪器的使用要点及注意事项. 仪器间条件仪器须置于干燥、恒温环境,以湿度小于70%、温度18～25℃为宜.因为光电流对震动极敏感,仪器须放在稳固的平台上.为确保输入电压严格稳定,须外接稳压器.
MPV microscope photometer is the use of photoelectric effect measurement of sample reflectance, transmittance, refractive index and many other optical constants of the instrument due to the use of different wavelengths of monochromatic light, as well as the measuring aperture and the aperture diaphragm in conjunction to use Improve the accuracy of the measurement.In order to ensure the accuracy of the measurement value and reduce or avoid the possible error, we must pay enough attention to the key steps in the process of instrument adjustment and operation.This article briefly introduces the use of the instrument and precautions. Conditions The instrument should be placed in a dry, constant temperature environment to humidity less than 70%, temperature 18 ~ 25 ° C is appropriate because the photocurrent is very sensitive to vibration, the instrument must be placed on a solid platform to ensure strict input voltage to be external Stabilizer.
