    Abstract: Provided is a spectrophotometer having a sample container 30, a light-source unit 10 for casting measurement light into the sample container 30, a photodetector 40 for detecting light obtained from the sample container 30 illuminated with the measurement light, a light separator 20 placed between the light-source unit 10 and the sample container 30, an A/D converter 50 for converting detection signals from the photodetector 40 into digital signals, and an A/D conversion time controller 65 for controlling an A/D conversion time in the A/D converter 50. The A/D converter 50 receives, for each A/D conversion time, detection signals sequentially produced by the photodetector 40, and sequentially outputs values corresponding to the amounts of signals received. The A/D conversion time controller 65 controls the A/D conversion time at five times (preferably, ten times) the cycle of commercial power supplies or longer during wavelength-correctness validation of the light separator 20.

    Abstract: Methods and optical detection systems (200, 300, 800, 900) for generating and processing a real-time time-domain cavity ringdown spectroscopy (CRDS) signal (831, 931) from an absorbing species in an optical detection system (200, 300, 800, 900) having an optical ringdown cavity (200, 300) are disclosed. The optical ringdown cavity (200, 300) is adapted for accepting a sample of an absorbing species. One or more modulated light signals (241,243,245,341) are generated using one or more light sources (240, 242, 244, 340). The light source(s) (240, 242, 244, 340) is pulsed at a specified pulse rate(s). The modulated light signal(s) (241,243,245, 341) is resonated using the optical ringdown cavity (200, 300) comprising a plurality of mirrors (220, 230), or sets of mirrors (320, 330), to produce the CRDS signal (831, 931). The reflectivity of the mirrors (220, 230), or sets of mirrors (320, 330), is dependent upon the pulse rate of the modulated light signals (241,243,245,341). Different beamlines (212, 214, 216, 312, 314, 316) are established by the modulated light signal(s) (241,243,245, 341) and the mirrors (220, 230, 320, 330) interacting with the absorbing species sample.

    Abstract: A spectroscopy system includes an array of quantum cascade lasers (QCLs) that emits an array of non-coincident laser beams. A lens array coupled to the QCL array substantially collimates the laser beams, which propagate along parallel optical axes towards a sample. The beams remain substantially collimated over the lens array's working distance, but may diverge when propagating over longer distances. The collimated, parallel beams may be directed to/through the sample, which may be within a sample cell, flow cell, multipass spectroscopic absorption cell, or other suitable holder. Alternatively, the beams may be focused to a point on, near, or within the target using a telescope or other suitable optical element(s). When focused, however, the beams remain non-coincident; they simply intersect at the focal point. The target transmits, reflects, and/or scatters this incident light to a detector, which transduces the detected radiation into an electrical signal representative of the target's absorption or emission spectrum.
