3I Lattice Light Sheet Microscope

• Capabilities: Primary purpose – live imaging of cell cultures and thin tissue sections (≤ 100 um). Lattice Light Sheet technique offers fast simultaneous two-color imaging in 3D and 4D producing large volumes of high-resolution fluorescence imaging data, with low photo-toxicity. Lattice-generated light sheet illuminates only a thin slice of the cell compatible by thickness with a working distance of the objective. Thus, out-of-focus light and photobleaching of the probes are substantially reduced. In comparison to other imaging methods, the lattice light sheet technique (1) substantially increases a signal to noise ratio and reduces the light exposure, (2) allows ultra-thin optical sectioning (3) ensures extremely low phototoxicity, (4) substantially increases a signal to noise ratio, (5) allows very fast time lapse imaging on the scale of milliseconds (6) increases resolution (XYZ = 230 nm x 230 nm x 370 nm).
• Making a lattice light sheet: The innovative Lattice Light Sheet combines the flexibility of a Gaussian light sheet with the thin optical sectioning of a Bessel beam to achieve the best optical sectioning of any light sheet microscope. Cylindrical lenses stretch and collimate the beam to form a sheet projected onto a spatial light modulator (SLM). SLM generates an optical lattice of Bessel beams. Annular mask lengths the sheet. The sheet is dithered in X and swept in Z by galvo mirrors. The thickness of the sheet is 0.4 um, and the length of the sheet may be modulated from 20 um to 70 um.
