QuVi SPIM
QuVi SPIM
The QuVi (Quantitative View) SPIM is a highly versatile light-sheet microscope that allows for true 3D volumetric imaging of living, fixed, and cleared samples. The QuVi SPIM exhibits a robust bench-top design, with an upright and symmetric, dual-view geometry and high precision, long travel range stages. Its light-sheet technology provides outstanding performance figures, especially in long-term imaging and high-throughput acquisitions. Thus, the QuVi is the optimal choice for dynamic, fast imaging, high-content screenings with isotropic resolution.
Simultaneous Dual-View or Dual-Channel Acquisition
The QuVi SPIM combines dual views with dual detection channels to enable large-scale 3D imaging of life specimens and cleared samples. The system enables fast and simple transition between living and cleared tissue imaging.
Typical applications of the microscope include living or fixed and cleared brain slices, long-term imaging of 3D cell culture models (spheroids, organoids, tumoroids), imaging of conventional cell culture in high throughput, and even functional (e.g. calcium) imaging.
Optimized Stability
The QuVi SPIM can be equipped with environmental control. Temperature can be adjusted between 20–37°C for optimal incubation conditions.
In addition, the QuVi SPIM also provides precise and stable environmental control (i.e. CO2, O2, N2, and humidity). Gas-concentration for the different components ranges between 0–15 % for CO2, 1–21 % for O2, and 20–99 % for H2O (humidity). The gas humidifier offers feedback control for precise regulation.
User-Friendly Software and Hardware
Hardware
Its novel stage design allows using SBS-format plates and provides an easy sample accessibility by means of its quick load feature. Since the objective lenses are exchangeable, a wide variety of samples of different sizes and preparations can be imaged.
Software
Luxendo's intuitive 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.
Many Design Features Make the QuVi Excel
Upright, Dual View and Dual Color
The QuVi SPIM combines easy accessibility with high throughput and well-controlled sample conditions, e.g. to perform screening experiments or biophysical methods such as FLIM and FCS.
Typical applications of the microscope include living or fixed and cleared brain slices, long-term imaging of 3D cell culture models (spheroids, organoids, tumoroids), imaging of conventional cell culture in high throughput, and even functional (e.g. calcium) imaging.
Illumination and Detection
The QuVi SPIM can achieve a resolution down to 340 nm in 3D, enabling live imaging, free of phototoxic effects.
The QuVi features a dual-side alternating illumination/detection concept and provides two orthogonal views of the sample.
The illumination optics comprise light-sheet generation by scanning a beam after passing a beam-shaper unit for length and diameter adjustment. Two Nikon 40x 0.8 NA water immersion objective lenses alternatingly project two orthogonal light-sheets on the sample. The expandable and upgradable illumination setup allows a range of up to six lasers. The alignment-free light-source offers 40mW power output for each line. For detection, the same objective lenses are used.
The two spectral detection channels equipped with 10 position high-speed filter wheels and a dichroic mirror changer enable simultaneous dual channel imaging. In addition, more than two channels can be acquired sequentially. The robust sCMOS Orca Flash 4.0 V3 cameras from Hamamatsu are well-suited for experiments that require high detection efficiency, quantification and speed.
Device Design
The QuVi SPIM's compact, vibration-free and robust design provides maximal stability during your long-term 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. 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 natural growth behavior of your sample are affected by the gentle image recording.
