Measurement of light and solar direct transmittance using the Model UH5700

The Model UH5700 spectrophotometer is a desktop spectrophotometer that can measure the transmittance, reflectance and absorbance of liquid and solid samples in the wavelength range of 190 to 3300nm. We have introduced new “UV Solution Plus” software (Figure 1) to improve user friendliness. The model UH5700 can be now used to measure the visible light and solar transmittance of glass in conformity with JIS R 3106





The model UH5700 spectrophotometer was equipped with a glass filter holder to measure the transmission spectrum of three types of glass (Figure 2).



Much higher values for both types of transmittance were obtained for sample A than for samples B and C, and it can be seen that light readily passes through sample A (Table 1). In addition, the solar transmittance for sample B was lower than its visible light transmittance. This is particularly true in the near-infrared region.
