Product overview

The LCS SPIM is the latest product in LUXENDO’s growing family of light-sheet microscopes. The basic configuration of the Luxendo LCS offers a cost-effective solution for cleared sample imaging. Based on a very versatile layout, the highly flexible upgrade options expand the performance of the system to increase speed and optical performance.

A quartz crystal cuvette, available in different lengths, facilitates mounting of large, delicate samples. The specimen is simply introduced into the cuvette filled with the clearing solution. The motorized sample stage for positioning and stack acquisition as well as the programmable optics concept for fast 3D scanning of the light-sheet through the sample ensure that the sample remains unperturbed during the imaging experiment while achieving the highest acquisition speed.

Typical applications of the microscope include imaging of large cleared-tissue samples, e.g. whole mouse brains to visualize complete neuronal and vascular networks. Microscopy of cleared organs or thick tissue samples is highly relevant in developmental biology studies and for cancer research, e.g. when investigating organ development, tumor structure and tumorigenesis.

Sample Chamber

An exchangeable quartz crystal cuvette simplifies the whole sample mounting procedure as well as cleaning and maintenance, while ensuring compatibility with a wide range of clearing solutions by covering a refractive index (RI) range from 1.33 to 1.57.

The cuvette is available in different lengths to accommodate samples of different sizes: the maximum cuvette dimensions are 40 mm × 20 mm × 20 mm (l × w × h).

Device design

The LCS SPIM's compact, robust and vibration-free design provides maximal stability even during long-term high-throughput experiments.

Tailored to fit your lab bench, this class 1 laser system does not require any air table or vibration compensation mechanism as all moving components are light-weight and balanced with the motor technology. Maximal stability of focus and thermal conditions are also guaranteed. The proprietary piezo crawler stages ensure longevity and precision for a permanently accurate specimen positioning. Neither the images nor the quality of your sample are affected thanks to the unique and very gentle image acquisition concept.

Illumination and Detection

The illumination optics comprise light-sheet generation by scanning a beam after passing a beam shaper unit for length and diameter adjustment. Two Nikon 4x 0.2 NA air objective lenses project two aligned light-sheets from opposing directions on the sample. The expandable and upgradable illumination setup allows a very flexible choice of lasers.

The detection optics comprises one Nikon 4x 0.28 NA air objective lens. An additional magnification changer results in a total magnification between 2x and 8x. The spatial detection arm is equipped with 10 position high-speed filter wheel. The robust sCMOS camera is well-suited for experiments that require high detection efficiency, quantification and speed.

Fast imaging mode

The basic configuration of the LCS SPIM can be upgraded with axial illumination scanning to extend the field of view (FOV) and to reduce shadowing effects.

Electronics, microscope control and computer

LUXENDO's browser-based user interface offers a simple setup and execution of multidimensional experiments, while real-time control is handled by an embedded controller to ensure microsecond precision timing independent of the PC’s performance fluctuations.

Precise timing control of all connected devices is a prerequisite for reliable experimental outcomes. Full control of data streaming to storage as well as GPU-supported image processing further complements the overall performance.
