Abstract:
A device for analysis of materials by means of radiation, includinga radiation source (6) for producing the radiation (34), a sample location (8) for accommodating a sample (10) of the material to be analyzed, a position sensitive detection device (9) for detecting the radiation (40) emanating from the sample, which detection device includes an array (42) of radiation sensitive detector elements (44), an electronic read-out circuit (48) which is connected to the detector array and includes charge amplifiers (58) in a one-to-one relationship with the detector elements (44), the input of said charge amplifiers being connected to a respective one of the detector elements, characterized in thatthe charge amplifiers (58) are constructed in the integrated bipolar technique, and that the electronic read-out circuit (48) includes digital signal processing circuits (74-82) which are connected to the outputs of the charge amplifiers and are constructed in the digital technique, wherein the digital signal processing circuits are accommodated on the same substrate as the charge amplifiers 58, and wherein the digital signal processing circuits are constructed by means of a BICMOS process in the form of the Current Mode Logic (CML) technique.
