Two-dimensional spectral characteristic measuring apparatus

摘要: This spectral characteristic measuring apparatus measures two-dimensional characteristics of a sample, and the includes collimator lens, band-pass filters, lenses an area sensor, which are arranged in order on optical axis L. The lens transforms light outputted from sample into pencil parallel light. filters have mutually-different passbands. identical focal distance correspondence with filters. sensor is at points constructed number imaging devices such as CCDs two-dimensionally. As described above, images spectrally separated by formed positions sensor. Therefore, can be simultaneously measured simple construction.
