    摘要： A variable wavelength optical filter module according to the present invention includes a package, a variable wavelength optical filter, and a detector. The package includes a reflection part (reflecting faces) in the inside of the package. The variable wavelength optical filter is disposed in the inside of the package and includes a first reflecting plate and a second reflecting plate facing each other, with a clearance between the first reflecting plate and the second reflecting plate being variable. The detector is disposed in the inside of the package and detects a ray of light having passed through the variable wavelength optical filter. Then, the variable wavelength optical filter and the detector are disposed on the opposite side to the reflection part (reflecting faces). The ray of the light incident into the inside of the package via the variable wavelength optical filter enters the detector via the reflection part (reflecting faces).

    摘要： A multipass spectroscopic absorption cell comprises at least a first reflector (40) and a second reflector (42) that are configured to reflect a beam of light multiple times through a sample volume (V). At least one of the first and second reflectors (40,42) defines a principal optical axis (A) that extends through the sample volume (V). An optical folding system (52) is located on the principal optical axis (A) between the first and second reflectors, said optical folding system being configured to fold the principal optical axis (A) through an angle greater than 0°.

    摘要： Raman spectroscopic analyzer including: a beam-casting unit 3 for receiving a light beam generated by a light source and for converging the light beam on a predetermined position in a perpendicular direction to the longitudinal direction of a measurement chamber through which a liquid sample is passed; and a light-receiving unit placed at a distance in the longitudinal direction from the predetermined position, for receiving scattered light emitted from the fluid sample. Among the scattered light which enters the light-receiving unit, the portion which enters this unit after being reflected by the inner wall surface opposite to this unit is eliminated, so that the amount of noise in the Raman spectroscopic measurement is considerably reduced.

    摘要： 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.

    摘要： A spectroscopic module 1 is provided with a spectroscopic unit 8 and a photodetector 9 in addition to a spectroscopic unit 7 and a photodetector 4 and thus can enhance its detection sensitivity for light in a wide wavelength range or different wavelength regions of light. A light-transmitting hole 4b is disposed between light detecting portions 4a, 9a, while a reflection unit 6 is provided so as to oppose a region R in a light-absorbing substrate 2, whereby the size can be kept from becoming larger. Ambient light La is absorbed by the region R in the substrate 2. Any part of the light La transmitted through the region R in the substrate 2 is reflected to the region R by the unit 6 formed so as to oppose the region R, whereby stray light can be inhibited from being caused by the incidence of the light La.

    摘要： In one embodiment, an improved multi-pass cell for a long path-length spectrometer is designed to include a perturbing mirror that causes a base pattern of reflections to be repeated multiple times, where each subsequent base pattern of reflections is rotated about the axis at an angle from a prior base pattern, to circulate the base patters about the cell. The base pattern may be a Herriott cell pattern. The improved multi-pass cell may be constructed with a concave front mirror centered along an axis of the cell, and a concave back mirror centered along the axis and facing the front mirror. The perturbing mirror may be centered along the axis, facing the front mirror and located at a perturbing mirror spacing in front of the back mirror or behind the back mirror, depending on the implementation.
