Total attenuated reflection photometer has radiation source, covering layer and radiation detector integrated in form of nest of components

摘要

Total attenuated reflection, comprising photometer (10) has a radiation source (20), a covering layer (11) and a radiation detector (22) that are integrated in the form of a nest of components, is new. The covering layer is a plate of silicon or quartz fixed in place by molten glass (15) or anodic bonding, and has optical elements in the form of V-section grooves (13) or rectangular section channels (14) in its surface. Total attenuated reflection, comprising photometer (10) has a radiation source (20), a covering layer (11) and a radiation detector (22) that are integrated in the form of a nest of components, is new. The covering layer is a plate of silicon or quartz fixed in place by molten glass (15) or anodic bonding, and has optical elements in the form of V-section grooves (13) or rectangular section channels (14) in its surface. One or more of the V-section grooves can have an optical filter coating, while grooves of similar shape in the radiation sources and/or detectors have a coating with a different spectral transmission. Cavities in the photometer can be filled with a protective glass.
