自动V棱镜折射仪主要用于玻璃、晶体等固体和液体材料折射率、色散系数和部分色散精密测量,与传统的目视V 棱镜折射仪相比,具有精度高、自动测量、自动计算和自动打印测量结果等特点,同时排除了目视测量引起的主观误差,提高了工作效率。仪器采用了一种新颖的总体结构方案,并且应用了微机技术,圆光栅测角技术、光电瞄准技术和自动寻的技术等近代科学技术,从而研制出一种操作方便、性能稳定,具有实用价值的国内外第一台自动V 棱镜折射仪。仪器测量光谱范围为400～750nm 内的七条主谱线折射率;可测量折射率范围1.3～1.95(在此范围之外精度降低);仪器的测量精度优于±1.5×10~(-1.5)。
Automatic V-Prism Refractometer is mainly used for the precision measurement of refractive index, dispersion coefficient and partial dispersion of solid and liquid materials such as glass and crystal. Compared with the traditional V-prism refractor, it has the advantages of high precision, automatic measurement, automatic calculation and automatic Print measurement results and other characteristics, while excluding the subjective errors caused by visual measurements, improve work efficiency. The instrument uses a novel overall structure of the program, and the application of computer technology, circular grating angle measurement technology, optical aiming technology and automatic search technology and other modern science and technology to develop a convenient, stable performance, and has practical value The first automatic V-prism refraction instrument at home and abroad. The instrument measures the refractive index of seven principal lines in the spectral range of 400-750 nm; the measurable refractive index range of 1.3-1.95 (accuracy outside this range decreases); the accuracy of the instrument is better than ± 1.5 × 10 ~ (-1.5) .
