Newton 7.0 – Vilber Optical ImagerSam Sandoval2022-08-17T09:59:59-04:00
The Newton 7.0 is an innovative optical bioluminescence, fluorescence, and 3D tomographic imaging system designed with the user in mind. It is ideal for in vivo, ex vivo and in vitro imaging applications, allowing for simultaneous imaging of multiple animals or samples at a time. It’s advanced features and software are easy to navigate and optimized for a multi-user interface. Furthermore, the intuitive workflow and advanced system sensitivity facilitates time-saving signal acquisition for longitudinal studies.
VILBER is a leading life science company developing and manufacturing fluorescence, chemiluminescence and bioluminescence imaging systems for applications ranging from small animal to cell biology research. Founded in 1954, Vilber is a leader in the molecular imaging sector, equipping more than 20,000 laboratories worldwide. An estimated 60,000 people use their products every day in over 100 countries.
The Newton 7.0 is a highly sensitive optical imaging system dedicated to pre-clinical imaging of small animals in vivo, and may also be used on a variety of in vitro and ex vivo samples. It combines the best optics and animal handling features for optimum scientific images and results. The Newton 7.0 systems are capable of bioluminescence, fluorescence as well as 3D tomographic imaging. The system is:
Does not require any radiation to acquire images
Is non-invasive, allowing for longitudinal studies
Allows for up to 5 mice or 3 rats to be imaged simultaneously
The Newton 7.0 offers 8 excitation channels in the visible RGB and near infrared spectrums. The very tight LED spectrum is additionally constrained with a very narrow excitation filter; these excitation sources are categorized as a Laser Class II due to their intense power. Movement of the excitation source over the entire FOV ensures consistent and reproducible results over the course of a longitudinal study.
Full Spectrum Tunability
8 excitation channels and 8 emission filters are available to cover the complete spectrum from Blue to infra-red.
Narrow bandpass filters are used for both excitation and emission to reduce cross talk between dyes, allowing for up to 3 dyes to be imaged simultaneously.
Macro-imaging to large throughput studies
Vilber’s intelligent darkroom architecture allows for fully automated movement of the camera (Z-axis) and animal pad (X/Y axis) to move through both the macro imaging FOV (6x6cm) to the full FOV (20x20cm) for imaging up to 5 mice.
Spectral unmixing is possible for both bioluminescence and fluorescence imaging when different luciferase enzymes or fluorescent dyes are used.
This system includes algorithms to remove crosstalk between the different signals, allowing for each channel to contain signal from only one reporter.
3D Optical Tomography
An integrated 3D tomography module allows both bioluminescence and fluorescence signals to be reconstructed in 3D and overlaid within a topographical model of the imaging subject.
For better understanding of anatomical and deeper tissue structures, the digital organ library allows for superimposition of the mouse organs and bones onto the topographical model.
State-or-the-art camera technology:
Scientific grade 16-bit CCD
-90oC delta cooling
10 megapixel image resolution
4.8 Optical Density
The advanced camera and optics provide increased sensitivity to either bioluminescence or fluorescence signals, with a very low signal to noise ratio. The high optical density allows for samples with both very low and high signals to be imaged without saturation, allowing for quantifiable results.
Images acquired at different time points can be arranged to form a longitudinal image sequence. For example, a time series could be constructed from images acquired on different days following an experimental treatment.
The software then compares the image data throughout the experimental treatment.
