1、 Characteristics:

1. This instrument can be used to quickly measure the refractive index, average dispersion, and partial dispersion of transparent or semi transparent solid and liquid substances(Can be tested immediately

calm706.5nm、656.3nm、589.3nm、546.1nm、486.1nm、435.8nm、434.1nmand404.7nmRefractive index of eight commonly used wavelengths).

When the grade of optical glass is known, its refractive index can be quickly measured, which is useful for the design and manufacture of optical instruments.

2.General instruments require a certain size when measuring the refractive index of a sample, and this instrument uses the preparation immersion method to obtain the refractive index of the sample

Protecting the tested sample is particularly important.

3.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 done in an optical glass factory

The trial production of new products is particularly useful.
