Nikon A1R-HD Confocal Microscope (Eclipse Ti2)

The Nikon A1R Confocal Microscope is a powerful, fully-automated confocal imaging system. The system is able to image in the X, Y, and Z planes with both a high-speed resonant scanner to capture the dynamics of a system and a Galvano scanner to maximize resolution in fixed samples. The A1R-HD a large field of view and is capable of a resolution below 200 nm. The system comes with sophisticated post-processing software to deconvolve and attractively display results. The system has a 2D and 3D tracking system for particle tracking can be set up to automatically track several regions of interest in a time series scan.

The system includes the following subsystems and components:

  • Nikon A1R Live Cell Resonant Dual Scanner
  • A1-DUG Hybrid GaAsP/PMT 4ch Detector System
  • Transmitted Light Detector
  • Nikon LUN4 4 Line Solid State Laser System
  • Ti2e Fully Motorized Inverted Microscope
  • Nikon Perfect Focus System
  • Motorized Encoded XY Stage
  • LED Based Epi Fluorescent System (DAPI, FITC, TRITC cubes)
  • LED Based Transmitted Light System
  • Lasers in the blue, green, red and far-red channels
  • 10x, 20x, 40x oil, 60x oil Objectives
  • 20x long-working distance objective for live-cell and dynamics imaging
  • DIC Imaging
  • Stage-Top Incubator for Temperature and Carbon Dioxide Control
  • Deconvolution software for improved visualization
  • Dedicated analysis workstation for processing images and making presentation quality images
  • Spectral Imager capable of 2.5 nm wavelength resolution and capture of 32 channels fluorescent spectra in a a single scan
  • Elimination of autofluorescence and separation of Fluorophores with overlapping spectra
