Title: (EN) Improvements in and relating to light transfer systems and improved cell investigation techniques arising therefrom
Abstract:
(EN) Apparatus as described by which very low light levels emitted typically by very small regions such as individual cells in cultured monolayers, can be more readily detected by a detector such as a CCD detector or image intensifier. The light capturing aid is a fibre optic face plate located between the light emitting material and the detector, but not in contact with the light emitting material. Where the latter is contained on a surface such as a petri dish, the face plate is positioned between the dish and the detector with at least an air gap between the face plate and the detector.
