Marianas LightSheet

Versatile Multiview Light Sheet Microscopy System for Imaging Model Organisms

Versatile Multiview Light Sheet Micrsocopy System for Imaging Model Organisms

Marianas LightSheet (MLS) combines the low phototoxicity and large sample space of dual inverted selective plane illumination microscopy (diSPIM) with the power and flexibility of a research-grade inverted microscope system. MLS supports a wide variety of specimen types and sizes as well as experimental designs including photoablation, photomanipulation, and computer-generated holography. Add spinning disk confocal, TIRF and FLIM to transform the system into a versatile multimodal imaging system all controlled with SlideBook software.

Flexible Sample Mounting

Multimodal Platform

Combine Marianas LightSheet with spinning disk confocal, holography and ablation systems for incredible flexibility on one system. Seamlessly control and switch imaging modes via SlideBook. LaserStack with FiberSwitcher enables millisecond switching of up to 7 lasers across modalities.


Dual Inverted Selective Plane Microscopy

Dual inverted selective plane microscopy (diSPIM) uses dual camera and scanner objective pairs positioned at 45° to the specimen plane to alternate capture and excitation between Path 1 and Path 2. The flexible system geometry allows for single- and dual-sided imaging with conventional sample mounting. SlideBook seamlessly controls all hardware modalities, deskewing, stitching/montaging, Multiview Reconstruction and joint deconvolution resulting in isotropic sub-cellular resolution across a wide range of samples. Marianas LightSheet integrates diSPIM with a research-grade inverted microscope enabling complex multi-modal light sheet experiments with photoablation, photostimulation and computer-generated holography.

SlideBook Multiview Reconstruction

SlideBook for MLS supports several methods to deskew, rotate, register and deconvolve diSPIM images. Dual-view capture registration is performed either through Point of Interest Detection or 3i’s proprietary Local Cross-Correlation and Registration algorithms. Results are instantly displayed in 3D for quick adjustment to achieve an ideal fit before joint deconvolution produces a fused image. Large datasets that would otherwise require high-powered computer resources can be automatically split into a computer’s available RAM and computed in parallel utilizing GPU-optimized processes.

SlideBook Software for Acquisition and Analysis

SlideBook software supports research microscopy through the entire experimental process. By managing everything from instrument control to image processing and data analysis, SlideBook allows scientists to focus on investigation rather than instrumentation. SlideBook controls hundreds of instruments in and around the microscope from dozens of manufacturers enabling researchers to integrate their preferred components and upgrade to the latest devices once available.

Powerful Computer Workstation

3i provides high-power computer workstations to control all microscope hardware necessary for acquisition as well as enable processing, segmentation and volume rendering of terabyte (TB) datasets without additional computer resources.  Solid state drives in RAID configurations provide high-speed storage for capture, while traditional high-capacity hard drives provide longer-term storage of datasets. NVIDIA Quadro GPUs work in parallel with the latest Intel Xeon processors for fast stitching, processing and rendering of captured data.

Petabyte Data Storage

3i offers DDN® unified storage systems to allow direct acquisition and analysis, without time-consuming file transfers, at volumes ranging from 500TB to over 2PB. DDN storage systems are an ideal choice for labs and facilities looking to optimize acquisition workflows and/or incorporate data analysis pipelines.
