摘要： Multi-modality imaging systems and methods for enabling controllable and/or automated switching between different imaging systems or modes. An imaging system includes a base plate having a first exposed region and a second region, a sample stage configured to hold a sample platform, and a first translation mechanism configured to translate the sample stage on the base plate along a first axis between a first position and a second position. In the first position the sample stage is positioned proximal to the first exposed region, and in the second position, the sample stage is positioned proximal to the second region. An illumination device is configured to illuminate a portion of the first exposed region, and a second translation mechanism is configured to translate the illumination device along a second axis substantially perpendicular to the first axis.

摘要： Filter wheel assemblies with a single actuation point to control positioning of front and rear optical filter elements simultaneously and to provide high channel density with a plurality of selectable optical filter pairs. A filter wheel assembly may include a plurality of optical filter element pairs arranged around a common axis, wherein each of the plurality of optical filter element pairs includes a first filter element and a complementary filter element, wherein each first filter element and each complementary filter element has a surface having a normal component directed toward an inner portion of the filter wheel assembly.
