Photobiological Safety – Photometric Testing

Definition of Photobiosafety: Photobiological safety means that the light emitted by various lamps and lamp systems (including various light-emitting devices) cannot have harmful radiation effects on living things (mainly humans). According to the wavelength of radiation and the physiological visual effects of the human eye, optical radiation can be divided into three parts: ultraviolet radiation,...
