👉 A refringer is a device used in the field of optics to adjust the wavelengths of light passing through it. It works by focusing or dispersing the light, allowing for more efficient transmission and conversion of light into other forms such as visible light, infrared, ultraviolet, or X-rays. In physics, refringers are often used in experiments where light is used to measure properties like temperature, pressure, density, or concentration (e.g., in thermometry). They are also commonly found in optical
