WebOptical sensorshave the ability to detect light, typically at a specific range of the electromagnetic spectra (ultraviolet, visible, and infrared). The sensor detects either wavelength, frequency, or polarization of light and converts it into electric signal due to photoelectric effect. Web3D sensing device makers have two key considerations when choosing an optical material for the SLI projector. 1.) The material must have the lowest coefficient of thermal expansion (CTE), so that it’s least susceptible to changes in temperature. This ensures that the device consistently delivers the most accurate pattern due to heat ...
