IEC 62595-2-4:2020（E）规定了具有多个激光设备和光学输出的激光模块的电光测量方法，用于需要光度和色度测量的各种显示器和显示照明应用，波长范围为380 nm至780 nm。该模块具有多个激光装置，如边缘发射激光二极管（LDs）、垂直腔表面发射激光二极管（VCSEL）或包括二次谐波产生（SHG）的光子上转换激光装置。该模块具有光学输出，例如光纤、波导管、光波导、透镜单元或其他光学元件，发射组合多个激光装置输出的激光束。

IEC 62595-2-4:2020(E) specifies the electro-optical measuring methods of laser modules with multiple laser devices and an optical output for various displays and display lighting applications which require photometric and colorimetric measurements, covering the wavelength range of 380 nm to 780 nm. The module has multiple laser devices such as edge-emitting laser diodes (LDs), vertical cavity surface-emitting laser diodes (VCSELs), or photon up-conversion laser devices including second-harmonic generation (SHG). The module has an optical output such as an optical fibre, waveguide, light guide, lens unit, or other optics, emitting a laser beam combining the output of the multiple laser devices.
