Glass spectral transmittance

The LSPA band of the silver monolayer is located in the spectral range of 400-520 nm (curve 2) with maximum at about 460 nm, that is at the copper interband absorption range. At the frequencies near the copper LSPA, the silver monolayer demonstrates high transmittance compared with glass substrate transmittance at this spectral range.

Fabry-Perot filters are also available commercially, with local continuously changing spectral transmittance. Such continuous filters are deposited on glass strips or on circular disks. 

Because OBAs excite below 400 nm and emit above 400 nm, AS/NZ 4399 recommends the use of a Schott UG-11 filter glass for monochromatic illumination. Its spectral transmittance is shown in Fig. 11. 

Simulating the surface climate, influence of radiation, convection, and heat flow were investigated, separately, and found that none of them can be neglected [8], Due to calculational limitations, irradiance was not included and spectrally resolved. Instead, outside the IP/DP box, it was approximated by ASTM G 173-3 spectral irradiance. For glass transmission, angle-independent spectral transmittance was supposed, for the whole range of direct radiation incident. 

LP-CVD ZnO Total and diffuse transmittance (TT and DT) for boron-doped LP-CVD ZnO films are shown in Fig. 6.17 as a function of the film thickness. TT remains superior to 85% in the spectral range [500-900 nm] for ZnO layers with d < 1.5 pm. Because 15% of the incident light is reflected due to the change of refractive index at the air/ZnO and glass/air interfaces, this means that, for d < 1.5 pm, the absorption of the LP-CVD ZnO B itself is too low to be measured by the spectrometer. TT is reduced by only about 5% for a thickness d = 3 pm. This means that 3 pm-thick ZnO films still have a high transparency, in spite of their relatively high thickness. For A > 900 nm,...

A lamp in which the irradiance from a low-pressnre mercury arc is transformed to a higher wavelength UV by a phosphor. The spectral power distribution of a fluorescent lamp is determined by the emission spectrnm of the phosphor and the UV transmittance of the glass tnbe.
