The present disclosure includes an optical head for a spectroscopic device configured to produce a beam of light, a reference signal detector, and a signal detector. A mirror reflects the beam of light from the light source toward a multi-sectioned window having a top side and a bottom side. The bottom side includes an AR coating and the top side has a first section including an AR coating and a second section including a beam splitter with transmittance and reflectance. A first beam path for the beam of light is defined by the mirror, the second section of the multi-sectioned window, and the reference signal detector. A second beam path for the beam of light is defined by the mirror, the second section of the multi-sectioned window, a medium contained in the spectroscopic device, an additional mirror, the first section of the multi-sectioned window, and the signal detector.

Multi-sectioned window for spectroscopic device

A light source module may include a base with a support feature protruding from a surface of the base and securing a light source to direct radiation away from the surface. A lens cells may be attached proximate to the surface, optionally by being secured within a sleeve that is attached at one end to the surface. A multi-conductor part may include electrical conductors and a base temperature sensor that contacts the base. The base temperature sensor may be electrically connected to at least one of the plurality of conductive elements and further connected to an optical ignition safety protection system configured to interrupt current to the light source if the base temperature sensor indicates that a temperature of the light source is outside of a safe range.

Light source module

A spectrometer cell can include a spacer, at least one end cap, and at least one mirror with a reflective surface. The end cap can be positioned proximate to a first contact end of the spacer such that the end cap and spacer at least partially enclose an internal volume of the spectrometer cell. The mirror can be secured in place by a mechanical attachment that includes attachment materials that are chemically inert to at least one reactive gas compound. The mechanical attachment can hold an optical axis of the reflective surface in a fixed orientation relative to other components of the spectrometer cell and or a spectrometer device that comprises the spectrometer cell. The mirror can optionally be constructed of a material such as stainless steel, ceramic, or the like. Related methods, articles of manufacture, systems, and the like are described.

Optical reflectors for spectrometer gas cells

A sample cell can be designed to minimize excess gas volume. Described features can be advantageous in reducing an amount of gas required to flow through the sample cell during spectroscopic measurements, and in reducing a time (e.g. a total volume of gas) required to flush the cell between sampling events. In some examples, contours of the inners surfaces of the sample cell that contact the contained gas can be shaped, dimensioned, etc. such that a maximum clearance distance is provided between the inner surfaces at one or more locations. Systems, methods, and articles, etc. are described.
