Atago NAR-1T Solid Abbe Refractometer

The Atago NAR-1T Solid is a versatile Abbe refractometer meticulously designed to measure the refractive index (nD) and Brix values of not only liquids but also solids, including glass, plastics, films, and crystals. Featuring a comprehensive measurement range of 1.3000 to 1.7000 nD and the ability to calculate Abbe numbers (optical dispersion), it is an essential instrument for optics, polymer science, and material engineering laboratories. It meets the high standards of industrial quality control and advanced research.

The NAR-1T Solid is fully compatible with contact liquids (e.g., monobromonaphthalene) and specialized test pieces for mounting solid samples onto the prism. Equipped with a built-in LED light source and a precise digital thermometer, it ensures measurement integrity across a temperature range of 5 to 50°C. With its capability to determine average dispersion values ($n^F-n^C$), this model provides deep insights into the optical characteristics of various materials. The Atago NAR-1T Solid combines laboratory-grade precision with the rugged reliability required for professional industrial analysis.
