MuVi SPIM LS Imaging Live Samples with Speed
Featuring a horizontal setup, the MuVi SPIM LS is designed to image large volumes of living objects very fast. The unique 4-axis concept with its two-sided illumination facilitates four orthogonal views of the sample without the need for rotation.
Caractéristiques
Illumination and Detection
The MuVi SPIM can achieve a resolution down to 300 nm in 3D (at a wavelength of 500 nm), enabling live imaging, free of phototoxic effects.
Two Nikon CFI Plan Fluor 10x W 0.3 NA water immersion objective lenses project two aligned light sheets from opposing directions on the sample. Detection includes two high numerical aperture Olympus 20x 1.0 NA or Nikon 16x 0.8 NA water immersion objective lenses. An additional magnification changer results in a total magnification that ranges from 12x to 33.3x.
MuVi SPIM LS Design
Lux DATA - A Comprehensive Data Processing and Storage Solution
Cutting-edge biological imaging like light-sheet microscopy, but also super-resolution or two-photon imaging, generates a vast amount of data required to provide researchers with all the relevant information about their samples. However, storage, transfer, and processing of the data remain a challenge.
Environmental Control
The MuVi SPIM can be equipped with environmental control. A Peltier based water cooling/heating system is available in the MuVi SPIM to keep the immersion medium at a homogeneous temperature, while the heated lid prevents condensation. Temperature can be adjusted between 20–37 °C for optimal incubation conditions.
In addition, the MuVi 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.

Microglia Response to Axonal Damage
The axon of a neuron in the zebrafish brain was selectively dissected by means of IR laser ablation (MuVi SPIM). Thirty minutes after ablation, four microglia reached the damaged axon.
