Light Sheet Microscopy

Improved fluorescence imaging using planar illumination

Light sheet systems are a novel method for imaging live samples. In light sheet microscopy, a sample is illuminated perpendicularly, rather than parallel to the imaging axis (as with traditional widefield or confocal microscopy).

BioVision is working with multiple manufacturers to design cutting edge light sheet systems.

diSPIM

The diSPIM is a flexible and easy-to-use implementation of Selective Plane Illumination Microscopy (SPIM) that allows for dual views of the sample while mounted on an inverted microscope. The diSPIM was co-developed by the NIH-based lab of Hari Shroff and Applied Scientific Instrumentation (ASI).

As an ASI distributor, BioVision has hands-on experience building diSPIM systems. Please contact us with any questions about this innovative technology.

L‑SPI

The L‑shaped Single Plane Illuminator (L‐SPI) is a flexible, low‐cost illumination module enabling ultra-low phototoxicity imaging of large specimens.

This simple and effective instrument recombines two uniform, wide light sheets at right angles, reducing shadowing without the need for sample rotation or image fusion.

The system offers optional sample chambers, a fast long‐travel piezo stage and a second L‑SPI head to bring sheets in from four directions. Its compact size and large freedom of access (e.g. for positioning micro‑electrodes) make it a highly flexible solution. These strengths allow adaptation of the L‑SPI for a wide range of experimental purposes.

It is designed to work with any macro‐ or microscope, single‑mode fibre laser source and scientific camera.

The L‑SPI was co-developed by Dr. Philippe Laissue of the University of Essex and Cairn Research, Ltd..
