Diffuse reflectance spectroscopy apparatus for use in analysing a sample comprising a sample receiving locationfor receiving a samplefor analysis; an illumination arrangementfor directing light towards a received sample; a detectorfor detecting light reflected by a received sample; and collection opticsfor directing light reflected by a received sample towards the detector. The illumination arrangement further comprises an interferometerand a half beam blockwhich is disposed substantially at a focus in the optical path for blocking light which exits the interferometer, passes said focus, and is reflected from re-entering the interferometer. A half beam blockmay be disposed in the optical path between the interferometer and the light sourcefor blocking light that exits the interferometer back towards the light source and is reflected by the light source from re-entering the interferometer and/or a half beam blockmay be disposed in the optical path on the opposite side of the interferometer than the light source.

Sample spinners and spectrometers including sample spinners

Diffuse reflectance spectroscopy apparatus for use in analyzing a sample comprising a sample receiving location () for receiving a sample () for analysis; an illumination arrangement () for directing light towards a received sample; a detector () for detecting light reflected by a received sample; and collection optics () for directing light reflected by a received sample towards the detector. The illumination arrangement further comprises an interferometer () and a half beam block () which is disposed substantially at a focus in the optical path for blocking light which exits the interferometer, passes said focus, and is reflected from reentering the interferometer. A half beam block () may be disposed in the optical path between the interferometer and the light source () for blocking light that exits the interferometer back towards the light source and is reflected by the light source from re-entering the interferometer and/or a half beam block () may be disposed in the optical path on the opposite side of the interferometer than the light source.

A spectroscopic instrument comprising a compartment () for housing instrument components () and desiccant () to protect the instrument components, and a deformable container () having at least one wall portion which is movable within the compartment () so as to vary the volume of the compartment () that is occupied by the deformable container as the container is deformed. The interior of the deformable container () is in fluid communication with the surroundings of the instrument, such that a difference in pressure between the compartment and the surroundings tends to cause the deformable container to deform, moving the wall portion.

Spectroscopic instrument

Systems and methods for attenuated total reflectance (ATR) spectroscopy. The systems and methods may generally involve differentiating an acquired image in a spectral domain, restricting a spectral range of the acquired image, subtracting an average absorbance from the restricted image data, and applying a principal component analysis to extract significant spectral features from the restricted image data.

Systems and methods for attenuated total internal reflectance (ATR) spectroscopy

An accessory for use with a microscope arranged to carry out ATR measurements has a support () which can be mounted on the moveable stage () of the microscope. A mounting () for an ATR crystal is carried on the support. The mounting () is preferably pivotally mounted on the support () so that it can be pivoted from a position in which the crystal lines on the axis of the microscope to a position in which a sample carried on the support can be observed visually. The mounting is arranged such that it can be returned reliably and reproducibly to its original position with the crystal on the axis.

Accessory for attenuated total internal reflectance (ATR) spectroscopy

An accessory for use with a microscope arranged to carry out ATR measurements has a support () which can be mounted on the moveable stage of the microscope. A mounting () for an ATR crystal () is carried on the support. A sample supporting member () is disposed below the location of the ATR crystal. The sample supporting member () has a relatively thin upper wall (). A pressure applying mechanism () is located below the wall () and is operable to apply pressure to a sample through the wall () to ensure good contact between a sample and the sample contacting surface of the crystal.

An accessory for use with a microscope arranged to carry out ATR measurements has a support () which can be fixed to the moveable stage () of the microscope. A mounting member () is carried by the support (). A sample supporting member () is disposed below the location of the ATR crystal (). The sample supporting member () is carried on the support () such that it can be moved to restricted extent relative to the support and defines a sub-stage which can be moved relative to the main stage () of the microscope.

Accessory for attenuated total internal reflective (ATR) spectroscopy

An accessory for use with a microscope arranged to carry out ATR measurements has a support () which can be mounted on the moveable stage of the microscope. A mounting () for an ATR crystal () is carried on the support. The accessory includes a registration indicium which is located at a fixed position relative to the sample contacting area of the crystal. The registration indicium is preferably provided at the apex region of the crystal. The registration indicium can be used to ensure correct focussing of a sample when obtaining an image of the sample.

An FT-IR microscope is operated in association with a scanning spectrometer in such a way that incremental movement of the movable stage of the microscope is synchronized with the scans of the scanning spectrometer. This minimizes delays in processing time.

Scanning IR microscope

An optical system capable of providing a magnification which can be varied comprises a pair of ellipsoidal mirrors &lsqb;( )&rsqb;which are so mounted and arranged that the focus for radiation reflected from one mirror corresponds substantially with the input focus for the other mirror. The mirrors are preferably mounted so that they are pivotable.
