Pv Focusing Mirror

We are well known company for Making, Exporting and Supplying of PV Focusing Mirrors from Beijing, China. Measure reflectance in various wavelength for Groove parabolic mirrors, heliostats, dish reflector and Fresnel reflection mirror. This system is used for measuring the surface figure of Grooved parabolic mirrors, heliostats, disc reflector and Fresnel reflection mirror, which used for concentrating solar thermal power. Focusing mirror is a device that gather the solar radiation into the energy accumulation collector, which plays the role of solar radiation high-density aggregation. It is the most critical component of solar thermal power generation system. If the mirror is not flat or parabolic curvature does not meet the requirements, it will have a significant impact on converging efficiency, so its measurement is crucial.
a a This system is portable and suitable for onsite detection. the wavelength range is 380nm to 2500nm. The system is composeMd by light source, a lens system, the diaphragm, the detector and the spectral data processing module.Incident beam with angle 8 A from the narrow light source toward the surface of the sample. At 8 A angle to the surface normal, it measure the mirror reflection by observing field angle.
