Realize the impossible: 4mm deep imaging: Take Imaging to New Depths with Transparent-rendered Specimens and a Dedicated Objective
SCALEVIEW-A2 revolutionizes the imaging of formalin-fixed specimens. Simply render mammalian brain tissue transparent through immersion in SCALEVIEW-A2 solution. Because SCALEVIEW-A2 eliminates light scattering, it doesn't decrease the intensity of signals emitted by fluorescent proteins in the tissue and so enables structures labeled with fluorescent proteins to be imaged in detail from the surface to significant depth, without the need for mechanical sectioning.
SCALEVIEW-A2 contains the fundamental components of ScaleA2 developed by the RIKEN Brain Science Institute in Japan. It is adjusted to achieve the optimal performance with the XLPLN25xSVMP objective.

SCALEVIEW Immersion 25X Objective for Multiphoton
Specially designed to deliver optimum performance with SCALEVIEW immersion, this dedicated multiphoton objective with an ultra-long working distance enables high-precision imaging of transparent-rendered biological specimens to a depth of 4 mm.
