The Marianas LightSheet™ merges the low phototoxicity and large specimen handling of dual inverted selective plane illumination microscopy (diSPIM) with the power and flexibility of a live-cell microscope system.
diSPIM employs two orthogonal objectives positioned at 45° above the specimen plane. By alternating between the objectives for imaging and excitation, diSPIM captures two volumes that are fused and deconvolved to achieve isotropic resolution.
Selective plane illumination microscopy (SPIM) uses a thin sheet of light to illuminate only the plane of interest, reducing phototoxicity by drastically cutting total light dose and allowing for prolonged specimen imaging.
The light sheet can be swept through the sample at high speed while a piezo moves the imaging objective to capture up to 3 volumes per second. Larger samples can be moved beneath the objectives.
The Marianas LightSheet™ allows for horizontal specimen mounting for conventional sample preparations such as coverslips and Petri dishes and provides a platform for custom-designed chambers. Embedding the specimen in gel is optional.
The open sample chamber accommodates specimens of various sizes. The inverted microscope enables easy sample location and positioning.
A light sheet from a scanned Gaussian beam enables rapid 3D imaging of samples ranging from single cells to organisms over the course of hours to days. The inverted microscope enables long term live cell experiments with available perfusion and incubator for full environmental control.
Four different scan modes allow for experimental flexibility whether your focus is on imaging speed, sample size or reduced light dose.
The Marianas LightSheet™ is a powerful live-cell imaging workstation that can be customized and combined with spinning disk confocal microscope, TIRF, FLIM, Laser Ablation, Photomanipulation and Digital Holography. SlideBook™ software seamlessly manages acquisition, alignment, registration, deconvolution and rendering.
Peak light intensity is greatest in point scanning methods. Total light dose increases in methods that illuminate the entirety of the cell.
SPIM is ideal for long-term live cell imaging due to the low light intensity
compared to confocal and laser scanning systems.
Integrated hardware and software control creates a seamless user experience with complete comprehensive control of acquisition and rendering.
