    Abstract: An absolute transmission accessory for a spectrometer. One example spectrometer system includes a base plate, a light source configured to transmit light, and an interferometer mounted to the base plate. The interferometer receives the light from the light source and output modulated light. The spectrometer system includes a first optical element configured to receive the modulated light and direct the modulated light, and a second optical element configured to receive the modulated light and focus the modulated light to a sample compartment. The spectrometer system includes a detector compartment including one or more detectors, the detector compartment configured to receive light from the sample compartment. The spectrometer system includes a sample holder coupled to the base plate. The modulated light is directed to the sample holder, and light exiting the sample holder is directed through the sample compartment and to the detector compartment via the second optical element.

    Abstract: The spectrometer 1 is provided with a package 2 in which a light guiding portion 7 is provided, a spectorscopic module 3 accommodated inside the package 2, and a support member 29 arranged on an inner wall plane of the package 2 to support the spectorscopic module 3. The spectorscopic module 3 is provided with a body portion 11 for transmitting light made incident from the light guiding portion 7 and a spectroscopic portion 13 for dispersing light passed through the body portion 11 on a predetermined plane of the body portion 11, and the spectroscopic portion 13 is supported by the support member 29 on the predetermined plane in a state of being spaced away from the inner wall plane.

    Abstract: A spectrometer comprises a light detection element provided with a light passing part (21) and a light detection part (22); a support (30) fixed to the light detection element such that a space (S) is formed between the light passing part and the support; a first reflection part (11) provided in the support and configured to reflect light passing through the light passing part in the space; a dispersive part (42) provided in the light detection element and configured to disperse and reflect the light reflected by the first reflection part in the space; and a second reflection part (41) provided in the support and configured to reflect the light dispersed and reflected by the dispersive part to the light detection part in the space.
