This upgradable expansion lens has an XFOV (extra-wide field-of-vision) at 24 x 24 cm and is used for use with any IVIS® Lumina system made after 2008. The IVIS® Lumina Series III pre-clinical in vivo imaging system brings together years of leading optical imaging technologies into one easy to use and exquisitely sensitive bench-top system. The IVIS Lumina III is capable of imaging both fluorescent and bioluminescent reporters. The system is equipped with up to 26 filter sets that can be used to image reporters that emit from green to near-infrared. Superior spectral un-mixing can be achieved by Lumina III’s optional high resolution cut-off filters.
