WYV-V Prism Refractometer

Product Usage

WYV-VPrism refractometer isMeasuring the refractive index, average dispersion, or partial dispersion of transparent or semi transparent liquids and solids is an essential instrument for optical instrument manufacturers, relevant research institutions, and universities. Adopting visual aiming, microscopic reading, fast speed measurement, high accuracy, easy to use, and simple operation.

Features:

This instrument can be used to quickly and accurately measure the refractive index, average dispersion, and partial dispersion of transparent or semi transparent solid and liquid substances(Can be measured immediately706.5nmThe656.3nmThe589.3nmThe546.1nmThe486.1nmThe435.8nmThe434.1nmand404.7nmRefractive index of eight commonly used wavelengths)When the grade of optical glass is known, its refractive index can be quickly measured, which is extremely useful for the design and manufacture of optical instruments;

When measuring the refractive index of a sample with a general instrument, a certain size is required. However, this instrument uses the precise preparation immersion method to obtain the minimum refractive index of the sample, which is particularly important for protecting the tested sample;

Due to the principle of the law of refraction, the refractive index of the tested sample is not limited by the refractive index of the prism of the instrument. This is particularly useful for the trial production of new products in optical glass factories;

Because the measurement accuracy of the instrument is5×10-5So the refractive index change of the material after high-temperature heat treatment can be measured.

Based on the above points, this instrument is one of the essential instruments for optical glass factories, optical instrument factories, and other related scientific research units, as well as for higher education institutions.
