Shortwave communication
optical filterShort pass filter refers to a specific wavelength range where the short wave direction is transmitted and the long wave direction is cut off, serving to isolate the long wave. Through the short wave effect, Hunan Ruicheng Optoelectronics
Short wave pass filterIdentify the positioning point with a wavelength point with a transmittance of 50%, and represent the model with SPF.
