FIELD: physics. ^ SUBSTANCE: simulator comprises the following arranged in series on a single optical axis: a light-emitting diode which emits in the 65020 nm wavelength range and connected to a light emitting diode with a first light filter which absorbs light with wavelength less than 620 nm, a pulsed xenon lamp, a diaphragm, a second light filter which corrects the radiation spectrum of the pulsed xenon lamp, a Fresnel lens and a spatial filter for smoothing luminous flux density on the area. Focal distance F of the Fresnel lens is linked to distance L between the diaphragm and the light emitting surface of the pulsed xenon lamp by a defined relationship. Diametre d of the diaphragm opening is (0.0100-0.0115)F cm; and the first light filter has a light-scattering surface facing the pulsed xenon lamp, and a smooth surface facing the light-emitting diode. ^ EFFECT: invention enables adjustment of mutual position of separate elements of photoelectric modules with concentrators, and increases accuracy of measurement. ^ 12 cl, 4 dwg |
