产品介绍： Alphamter We offer an easy-to-handle device fort he measurement of the solar reflectance of surfaces. The solar absorptance is automatically calculated as the complimentary part, which is always the case for opaque samples.
You will get a first spectral information because our instrument is using different pairs of LEDs and detectors, which are mounted at the highly reflecting (made of bulk PTFE) wall of an integrating sphere. This sphere serves as a diffuse light source, which enables measurements of the hemispherical reflectance, or the directional absorptance, respectively.我们提供一个easy-to-handle测量装置的堡垒他太阳能反射率的表面。太阳吸收率的自动计算出的是免费的部分,它总是此案不透明的样品。 你会得到一个第一光谱信息,因为我们的仪器是使用不同的照片,发光二极管和探测器安装在高反射(PTFE)做成的墙体积积分球。 这个球作为扩散光源,使测量的半球形或定向吸收率的反射系数,分别使用。 Specifications:规格: - Wavelength range: 0.3µm – 1.4 µm波长范围:0.3µm - - 1.4µm - Sphere material: PTFE (Hostaflon)材料:聚四氟乙烯(-球体Hostaflon) - Sphere diameter: 50mm球体直径50毫米- - Diameter of measured area: 16mm-直径16mm测量的面积: - Reproducibility: < 0.5%再现性:< 0.5% - uracy: < 3%精确度:< 3% |
