WYV V prism refractometer Introduction: This instrument can be used to quickly and accurately determine the refractive index, average dispersion and partial dispersion of transparent or translucent solid and liquid substances (ie, can measure 706.5 nm, 656.3 nm, 589.3 nm, 546.1 nm, 486.1 nm, 435.8 nm, 434.1). Refractive index of eight common wavelengths such as nm and 404.7 nm). The refractive index can be measured quickly when the optical glass grade is known, and these data are extremely useful for the design and manufacture of optical instruments. Generally, the instrument needs to have a certain size when measuring the refractive index of the sample, and the instrument can obtain the minimum refractive index of the sample by using the precise preparation of the immersion method, which is especially important for protecting the sample to be tested. Since this instrument is based on the principle of refractive law, the refractive index of the sample to be tested is not limited by the refractive index of the instrument prism. This is especially useful for new product trials in optical glass plants. Since the measurement accuracy of the instrument is 5 × 10 - 5 , the refractive index change after high temperature heat treatment of the material can be measured. In combination with the above points, the instrument is one of the necessary instruments for optical glass factories, optical instrument factories and other related scientific research institutions and institutions of higher learning.
