Advanced pre-clinical
optical imaging
The IVIS® Spectrum advanced
pre-clinical optical imaging system
combines high throughput and full
tomographic optical imaging in one platform. The system uses leading optical
imaging technology to facilitate non-invasive longitudinal monitoring of
disease progression, cell trafficking and gene expression patterns in living
animals. Take full advantage of bioluminescent and fluorescent reporters
across the blue to near infrared wavelength region using optimized set
of high efficiency filters and spectral unmixing. It also offers true 3D
tomography for both fluorescent and bioluminescent reporters that can be
analyzed in anatomical context against a Digital Mouse Atlas or registered
with other tomographic technologies such as MR, CT or PET through the
multimodality module.
World-leading optical imaging system:
uncompromised sensitivity and flexibility
Transmission and epi-illumination imaging
Emitted light from the excitation filter wheel feeds through
a fiber optic bundle to illuminate the specimen from either
the top, in epi-illumination (reflectance) mode, or from
underneath the stage, by means of an automated bundle
switch. Transilluminating the subject from below at precise
x,y-locations allows for transmission imaging, enabling
more sensitive detection and accurate quantification of deep
sources. Transmission fluorescence imaging also reduces the
effects of autofluorescence.
Narrow Band Excitation and Emission Filters
The IVIS Spectrum excitation and emission filters enable
spectral scanning over the blue to NIR wavelength region.
• 10 narrow band excitation filters: 415 nm – 760 nm (30 nm
bandwidth)
• 18 narrow band emission filters: 490 nm – 850 nm (20 nm
bandwidth)

Versatile field of view – single cell to five mice
Figure 3. From 20 microns to localize single cells to five whole mice, the IVIS Spectrum gives you the automated flexibility, throughput and resolution required to
quantitate functional developments in whole animals down to a single cell.
Bioluminescence imaging- best in class
in vivo sensitivity
IVIS Spectrum has a cooled (-90ºC) camera with large CCD
chip area and low F-stop for high sensitivity bioluminescence
light detection. Image multiple bioluminescent reporters like
firefly luciferase, Renilla luciferase and bacterial luciferase
in vivo at depth rapidly and quantitatively. The ultra sensitive
camera optics allows the detection of as few as five cells
(Figure 4), earlier monitoring of micormetastais in vivo and
track tumor development longitudinally in vivo (Figure 5).

(top) and monitoring metastasis post intracardiac injection of MDA MA-231luc2 cells (bottom) longitudinally.

Fluorescence imaging – versatility in fluorescence
The IVIS Spectrum can image and quantify all commonly used
fluorophores, including fluorescent proteins, dyes and
conjugates. IVIS Spectrum achieves superior spectral unmixing
through a wide range of high resolution, short cut-off filters
and advanced spectral unmixing algorithms. Spectral unmixing
not only allows detection and separation of multiple reporters,
but greatly reduces the effects of tissue auto-fluorescence.
PerkinElmer offers the broadest portfolio of fluorescent agents
and dyes for in vivo applications. The IVIS Spectrum is the most
sensitive system to visualize these fluorescent agents in various
in vivo applications (Figure 6, 7).

Multispectral Imaging with Advanced Spectral
Unmixing Algorithms
Absolute localization in optical imaging –
3D analysis
Living Image® Software is designed to simplify advanced and
complex biological models by intuitively guiding the user
through experiential setup and analysis. The imaging wizard
with the newly added probe library will help design imaging
settings and select the right filter pair for fluorescence studies.
The software also offers a step by step guide for spectrally
unmixing multiple fluorescent signals from the same animal.
Look deeper, see further, and take science to a new level of
sophistication with the 3D technology from PerkinElmer.
3D diffuse tomography utilizes structured light data with
bioluminescence or fluorescence images to reconstruct three
dimensional representations of light emitting reporters and
compute signal strength (Figure 9). Take the next step and
analyze 3D sources in an anatomical context with the Digital
Mouse Atlas. The tomography tool allows the quantification of
number of cells and dye concentration in a tumor and 3D
coregistation of both bioluminescent and fluorescent reporter
(Figure 10).
Advanced spectral-unmixing algorithms and a broad range of
high spectral resolution filter sets minimize autofluorescence
and provides the opportunity to image a wide variety of
targeted and activatable fluorescent probes and reporters.

reporters simultaneously.

• View sagittal, coronal and transaxial sections through a
3D image
• View optical sources from multiple perspectives by converting a static 3D image into a movie of a

Multimodal co-registration
The IVIS Spectrum is the most advanced in vivo imaging
system available on the market today – not only can it
quantitate and localize 3D fluorescent and bioluminescent
sources in vivo, but it can import and automatically
co-register CT (Figure 12, 13 and 14) or MRI images yielding
anatomical context. No need to confine or morph your
subject, structured light measurements provides clear
anatomical reference for co-registration. Maximize the
content extracted from preclinical models by integrating
diverse imaging modalities in a single longitudinal study.
