Light sheet and confocal microscope

The Department of Biology possesses two confocal microscopes, one Zeiss LSM 510 META and one Leica SP8 DLS that is also a light sheet microscope. Both microspores are available – against a user's fee after initial training.

Light sheet microscopy

Light sheet microscopy – also referred to as single plane illumination microscopy (SPIM) is a is a gentle way of imaging sensitive samples or fast biological processes /in vivo/. The specimen is illuminated only in a single plane at a time and detected from the perpendicular direction. Since there is no out-of-focus excitation, phototoxic effects are reduced to the focal plane. Light sheet imaging has intrinsic optical sectioning. By moving the sample through the light sheet, 3D images of a specimen can be recorded. With this technique large 3D volumes are captured at a much higher speed but slightly lower resolution compared to confocal imaging.

Confocal microscopy

Confocal microscopy – or to be more precise: confocal laser scanning microscopy (CLSM) – is a method that is particularly suited for microscopy of fluorescent or reflecting specimens. The confocal microscope eliminates out-of-focus light, and creates a clear view of structures in the focal plane – also in specimens that are to thick for conventional fluorescence microscopy.

If you acquire a series of confocal images at different depths in a thick specimen, the image series can be used for 3D analysis and 3D rendering and you can visualize structures that could not be distinguished in conventional light microscopy.

Our Zeiss LSM 510 META is equipped with:

Light source : four lasers, with the wavelengths:

  • DPSS 405 nm (excitation of e.g. DAPI, Hoechst 34580)
  • Ar ion laser: 458, 477, 488, 514 nm (488 nm for excitation of e.g. Cy2, Alexa488, GFP, FITC)
  • DPSS 561 nm (excitation of e.g. Cy3, Alexa 546 – Alexa 592, Texas Red, TRITC)
  • HeNe ion laser: 633 nm (excitation of e.g. Cy5, Alexa633 - Alexa 647)

Detectors: two PMT:s (photomultiplier tubes) and a META detector
Objectives: 5x/0.15, 10x/0.45W, 20x/0.8, 25x/0.8IMM, 40x/1.3Oil, 63x/1.4Oil
Software: ZEN 2009
