Abstract: 【課題】レーザ光を回転拡散板によって、空間的にランダム化する場合、空間的パターンが繰り返されることを防止し、均一性を向上させる放射線デリバリ装置を提供する。 【解決手段】マイクロスコープ用レーザビームデリバリ装置14は、それぞれ異なる周波数で周期的に移動するように構成された第1および第2光学拡散板50,60を有する。それぞれの光学拡散板は回転するディスクを有してもよい。レーザ光18は、第1回転拡散板50によって、空間的にランダム化され、第2拡散板60によって、その空間パターンはさらにランダム化される。第2拡散板60は、第1拡散板50の1回転の後において、いずれかの空間的パターンが繰り返されることを防止する。これは、光が回転する共焦点ディスクを通じて撮像される場合、うなりパターンが生じることを防止し、他の場合において、均一性を向上させる。 【選択図】図1

Abstract: 【課題】微分位相差(DPC)顕微鏡法を行うための顕微鏡で照明源が物体から作動距離に配置することにより、使用者は、試料領域に制限なくアクセス可能とする。顕微鏡には、標準的な対物レンズが使用されるこのことによりコストが削減する。 【解決手段】微分位相差(DPC)顕微鏡法を行うための顕微鏡100は、無限遠補正顕微鏡対物レンズ7と、チューブレンズ10と、顕微鏡対物レンズの後焦点面を顕微鏡対物レンズの外側の共役後焦点面に結像するように構成された少なくとも1つのレンズを備える。共役後焦点面には、開口絞りが配置されている。物体面は、対物レンズと照明源との間に位置する。照明源は、物体面に対して垂直な軸の周りで角度方向にずれた複数の位置のうちいずれか1つから物体を照明するように構成可能である。 【選択図】図1

Abstract: The present invention provides a spectrometer, comprising: an inlet for the receipt of incident light; an optical path for transmitting the incident light from the inlet to an analysis plane; a focusing element located along the optical path, wherein the spectrometer has an in-focus position in which a focal point of the spectrometer and the analysis plane coincide; and a controller adapted in use, when a removable light disperser is placed along the optical path, to cause the spectrometer to be in the in- focus position by controlling the position of the focusing element relative to the analysis plane. The spectrometer is used in the analysis of light from a light source and, due to the ability of the controller to manage the focus point by way of moving the focusing element, the spectrometer is able to bring itself into an in-focus configuration without the need for a user to intervene.

Abstract: A microscope comprises a microscope objective, a camera and an imaging optical system for imaging an object through the objective to the camera along a first optical path. A projection optical system is provided for projecting a test image onto the object through the objective, and the imaging optical system is configured to image the projected test image from the object to the camera through the objective and along at least part of the first optical path. A focus adjustment system is provided for focusing the test image at the camera. Using the same objective and the same camera for both imaging and focusing allows reduction of the cost of the microscope in comparison with known microscopes that provide separate focusing systems.

Abstract: A microscope system has an illumination optical system comprising a multi-mode optical fibre having an egress for emitting a laser beam. The egress is located in a plane that is conjugate to the microscope sample plane. The illumination optical system is configured such that the laser beam is incident at the objective lens laterally displaced from the principal optical axis of the objective lens in order that the objective lens delivers the laser beam to the sample plane at an angle that is oblique to the principal optical axis. Utilization of a multi-mode optical fibre for laser delivery in oblique illumination microscopy, such as TIRF microscopy, solves problems associated with using single-mode optical fibres such as alignment and uniformity of illumination.

Abstract: A Raman analysing apparatus comprises an imaging optical system for imaging an object along an optical path to an optical detector, an irradiation optical system for illuminating the object, and a scanning device comprising a spinning pinhole disk. The irradiation optical system directs light onto the scanning device to illuminate the object at a plurality of illumination points. The imaging optical system images Raman scattered light emitted from the object at the illumination points to an intermediate image plane at which the scanning device is located. The imaging optical system may include a spectral filter and/or at least one optical spectral analyser. The apparatus enables high speed confocal Raman imaging and/or high speed confocal Raman spectography to be performed.

Abstract: A support assembly for a heat pump system comprising a base and a plurality of platforms for supporting a respective heat pump such as a thermoelectric cooler. Resiliently flexible pipes support the platforms with respect to the base and form part of a coolant circulation system. The platforms are movable with respect to each other and the support structures allow the platforms to move with respect to the base. An object to be cooled, such as an image sensor, is mounted on the heat pumps. The platforms are able to move in response to expansion and contraction of the object thereby preventing damage to the heat pump system.

Abstract: A laser beam delivery apparatus for a microscope comprises first and second optical diffusers that are configured to move in a periodic manner with a respective different frequency. Each optical diffuser may comprise a spinning disk. The laser light is spatially randomized by the first spinning diffuser and its spatial pattern is further randomized by the second diffuser. The second diffuser prevents any spatial pattern from repeating after one revolution of the first diffuser, which prevents beating patterns from forming when the light is imaged through a spinning confocal disk and increases the uniformity in other cases.
