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 spectrometer includes a light source that emits a beam into a sample volume comprising an absorbing medium. Thereafter, at least one detector detects at least a portion of the beam emitted by the light source. It is later determined, based on the detected at least a portion of the beam and by a controller, that a position and/or an angle of the beam should be changed. The beam emitted by the light source is then actively steered by an actuation element under control of the controller. In addition, a concentration of the absorbing media can be quantified or otherwise calculated (using the controller or optionally a different processor that can be local or remote). The actuation element(s) can be coupled to one or more of the light source, a detector or detectors, and a reflector or reflectors intermediate the light source and the detector(s).

A pressure measurement device includes a housing having an inlet, a transducer coupled to the inlet to generate an electrical signal representative of pressure at the inlet, and a data communication device coupled to the transducer to transmit a wireless signal corresponding to the electrical signal.

This Inductive Displacement Transducer relates to a new and useful set of embodiments for a comparator-type relaxation oscillator circuit where the frequency is controlled by variable inductance. Each oscillation of said circuit discharges a fixed amount of charge such that an increase in frequency increases the total current draw of the circuit.
