感光材料所用显微技术,实际多是属于测微范围。观测的项目有:颗粒、厚度、吸水胀量、解象力等。测试时可用放大倍率在1500倍以上一般生物光学显微镜。首先要校准测微尺,测微尺分为接目测微尺和接物测微尺,两者必须配合校准后才能使用。接目测微尺是在圆型玻璃片上,以 Sensitive materials used in microscopy, the actual mostly belong to the micrometer range. Observation of the project are: particles, thickness, water absorption expansion, such as anti-imaging. Available magnification test at 1500 times more than the general biological optical microscope. First of all, to calibrate the micrometer, micrometer ruler is divided into the sighting micrometer and then measuring micrometer, both must be calibrated before use. Visually inspect the micrometer is in the round glass to
