WebThe index of refraction ranges from approximately 1.45 - 2 for visible materials and 1.38 - 4 for IR materials. In many cases, index of refraction and density share a positive correlation, meaning IR materials can be heavier than visible materials; however, a higher index of refraction also implies diffraction-limited performance can be achieved with fewer lens … WebApr 15, 2024 · When the temperature is 20 °C, the sensor can detect the sensor performance in a range of refractive index from 1.33 to 1.40.
