Abstract:
Ein spektralanalytisches Gasmeßgerät weist eine Strahlungsquelle (36), einen Sendekondensor (19), ein Objektiv (13) und einen Strahlenteiler (11) auf, welcher zumindest einen Teil der von einem Reflektor (40) in sich zurückgeworfenen Strahlung zu einem Polychromator (32) lenkt. Die Sendestrahlung fällt hinter dem Strahlenteiler (11) auf einen zwischen zwei Stellungen verstellbaren Umlenkspiegel (12), welcher das Licht einem Objektivreflektor (13) zuführt. Der Objektivreflektor (13) reflektiert die Strahlung zu einem gegenüber der Strahlungsdurchtrittsöffnung (14) angeordneten Nachführspiegel (15). Es ist wenigstens ein lang- und ein kurzbrennweitiger Objektivreflektor (13) vorgesehen, um in Zusammenwirkung mit dem verstellbaren Umlenkspiegel (12) unterschiedliche Reichweitenbereiche zu gewährleisten.
Abstract:
A gas analyzing apparatus for laser absorption spectroscopy measurement includes a laser light source to generate laser beam with a specific wavelength absorbed by a component being measured in sample gas, a laser light source drive controller to control driving of the laser light source, an optical detector arranged at a location where the laser beam is received, a gas cell for measurement of the sample gas which is arranged on an optical path of the laser beam going from the laser light source to the optical detector, and a computing unit to calculate a concentration of the component being measured in the sample gas in accordance with a detection signal of the optical detector. Further, the gas analyzing apparatus has at least one calibration gas cell where calibration gas is filled with, and a calibration gas cell mounting mechanism capable of locating one of the calibration gas cells in a removable manner on the optical path of the laser beam.

Abstract:
Reference cell (8) for use with a fibre optic probe (1) comprising a base wall (11), upstanding walls (12) each having an optical window (13, 15), and a top wall (14) having a further optical window (16) adapted to allow light to pass to and from a fibre optic probe. The base wall (11) comprises a reflector (19) which reflects incident light from the fibre optic probe back to said probe (1). The top wall (14) has an attachment for receiving an emitting and a receiving end of a fibre optic probe (1). The cell (8) allows use of standard fibre optic probe (1) with other optical equipment when the path length and the probe optical characteristics require validation to international standards. The calibration of the probe (1) is analogous to calibration of laboratory spectrophotometers and can therefore be validated. The device (8) enables probes (1) to be used for applications where precision and accuracy are essential.

Abstract:
An apparatus and related method for optical calibration of spectrophotometers is described. The apparatus is a calibration plate including one or more cuvettes filled with solutions of interest. The cuvettes are sealed to prevent evaporation. The cuvettes also possess a compressible component to allow for expansion of the solution and a bubble control apparatus to ensure that the compressible component does not intersect the beam path. A piece of neutral density glass is optionally included in the apparatus to track optical changes of the solutions over time.
