The Nikon A1si is a confocal system equipped with a point-scan scan head, 5 standard PMT detectors and a 32-channel PMT spectral detector. The A1si's highest resolution mode is up to 4096 x 4096 pixels. The system is mounted on a Nikon Ti2000E inverted, fluorescence microscope with DIC optics. NIS Elements imaging software is used to control acquisition and analysis.

Advantages of multispectral imaging and unmixing has been shown in hundreds of publications to reduce autofluorescence by as much as 100-fold, both for microscopy and FFPE tissues and in small animal and plant fluorescence imaging.
