Confocal Laser Microscopy
The Nikon A1R-ER is a point-scanning confocal that contains a dual scanning system built into the scan head. It has both a high resolution galvanometer scanner and a high speed resonance scanner. The galvanometer scanner scans a single illumination point over the image field as fast as 8 frames/sec for a 512 x 512 pixel field and can be used to acquire high spatial resolution images at up to 4096 x 4096 pixels. The resonance scanner can be used to acquire highly temporarily resolved images at up to 15 frames/sec at 1024 x 1024 pixels resolution or 420 frames/sec in band scan acquisition mode at 512 x 32 pixels resolution. A deconvolution module provides for Enhanced Resolution of acquired images. Signal is detected with 2 GaAsP and 2 high sensitivity PMTs for visible lasers, emission sets for 450/50, 525/50, 600/50 (UV/GFP/RFP/Cy5) and the system is set on an inverted Ti2 stage with Perfect Focus System (PFS4) allowing for live cell work. The Ti2 is an exceptionally stable, drift-free platform with hardware-triggering capabilities and high-speed imaging applications allowing quick complete slide scanning. This confocal is driven by the NIS-Elements software platform.
