Zeiss LSM META
Manufacturer: Zeiss
Location: Britanya 233
Acquisition Date: 2006
Details
The unique scanning module is the core of the LSM 510 META. It contains motorized collimators, scanning mirrors, individually adjustable and positionable pinholes, and highly sensitive detectors including the META detector. All these components are arranged to ensure optimum specimen illumination and efficient collection of reflected or emitted light. A highly efficient optical grating provides an innovative way of separating the fluorescence emissions in the META detector. The grating projects the entire fluorescence spectrum onto the 32 channels of the META detector. Thus, the spectral signature is acquired for each pixel of the scanned image and subsequently can be used for the digital separation into component dyes.
