Design and Fabrication of edge filter using absorbed ZnS single layer prepared by flash evaporation technique

摘要

Long-wave pass edge filter of high transmittance and wide bandpass have been designed and fabricated using on a single weakly absorbed ZnS thin film material of thickness of about 300 nm which was prepared by using the flash evaporation technique. The design was based on characteristic matrix theory, taking into account the effect of dispersion phenomena for all spectral wavelength.
