The Light Microscopy Suite houses a number of high-end light microscopes, designed to provide a specific capability depending on experiment requirements. Discussion with IRF staff will help you ascertain the perfect microscope for your needs but the information presented on these pages will introduce each system in the IRF portfolio. 

The functionality of a microscope can broadly be described using the metrics of Resolution, Speed, and Depth of imaging, and these factors play an important part in the decision of which microscope to use – often there is a trade-off made in order to achieve extremes of any given capability; such as sacrificing speed of imaging for greater resolution. These metrics can be graphically represented as shown below, with an overlay of various microscopy platforms.

Nikon A1R

Nikon A1R

The Nikon A1R confocal microscope at the facility is an automated inverted system featuring a dual scanhead design, enabling both Galvano mode for high-resolution imaging and Resonant mode for high-speed acquisition. Its highly sensitive GaAsp detectors ensure clear, high-resolution images, even from faint signals.

Equipped with an Okolab environmental chamber and stage-top incubator, the microscope allows precise control of temperature and gases, ideal for time-lapse imaging of live samples. It also includes various sample holders for glass slides, Ibidi plates, Petri dishes and microwell plates. We recommend using a cover slip with thickness of 0.17mm when using this equipment.

The Nikon A1R includes the following objectives:

  • 10x CFI Plan Fluor DLL (0.3 NA, Ph1, WD: 16 mm)
  • 20x CFI Plan Apochromat VC (0.75 NA, WD: 1 mm)
  • 40x CFI S Plan Fluor ELWD (WD: 2.8-3.6 mm, correction collar: 0-2.0 mm)
  • 60x Oil CFI Apochromat Lambda S (1.42 NA, WD: 0.15 mm, chromatic correction: 405-656 nm)
  • 100x Oil CFI Plan Apochromat Lambda D (1.45 NA, WD: 0.13 mm, chromatic correction: 435-850 nm)
  • 60x Water CFI Apochromat IR (1.27 NA, WD: 0.17 mm, chromatic correction: 435-1064 nm)

Image acquisition and analysis are streamlined with Nikon NIS-Elements C software, enabling users to go from data collection to publication-ready figures in one session.

For advanced image processing, the system includes a deconvolution module as well as the NIS.AI suites, which features Enhance.ai, Segment.ai, Clarify.ai and Convert.ai.

Nikon Ni-E

nikon nie

The Nikon NiE is a modern upright research widefield microscope equipped with a Nikon DS-Fi3 camera for both color and emulated monochrome imaging. This allows for high-resolution brightfield and fluorescent imaging. The CoolLED pE300, a broad-spectrum LED fluorescent light source, provides excellent illumination for a wide range of applications.

The NiE includes the follwoing objectives;

  • 10x Plan Fluor DLL (NA: 0.3, Ph1, WD: 16 mm)
  • 20x Plan Fluor  (NA:0.66, DIC, WD: 2.1 mm)
  • 40x CFI Plan Fluor (NA: 0.75, WD: 0.66 mm)
  • 60x oil Plan Fluor Lambda (NA: 1.40, DIC, WD: 1.3)

Controlled by Nikon NIS-Elements software, the NiE is user-friendly and ideal for viewing slides. It features five fluorescent filters—DAPI, FITC, TRITC, CY3, and CY5—providing versatility for automatic fluorescence image capture and analysis.

T-SPIM

tspim

The T-SPIM is a custom-built light sheet microscope designed with dual-sided illumination, ensuring even excitation of large samples such as zebrafish embryos and spheroids. Imaging occurs in a sealed chamber where the sample is immersed in a selected medium, such as PBS or cell culture medium.

T-SPIM (Selective Plane Illumination Microscopy) combines the optical sectioning capabilities of a confocal microscope with the speed and sensitivity of widefield imaging. By exciting the sample with a sheet of laser light, T-SPIM selectively illuminates only the imaging plane, minimizing photobleaching and reducing off-plane excitation, which can impair image resolution in conventional widefield microscopy.

The system supports 10x, 20x, or 40x detection objectives, depending on your sample. Please discuss your imaging needs with IRF staff in advance of your session.

Hamamatsu Nanozoomer

nanozoomer

The NanoZoomer 2.0-RS slide scanner from Hamamatsu allows the scanning of up to six standard (76mm x 26mm) or two double-size (76mm x 52mm) slides in a variety of modes: manual, semi-automatic, and automatic. 

Scanning can be done at 20x (0.46 µm/pixel) and 40x (0.23 µm/pixel) magnification, with scan times as fast as 1 minute 40 seconds for a 20mm by 20mm area at 20x magnification, with 40x magnification increasing the scan time proportionally. 

This system allows the generation of high-resolution images of the entire slide, allowing image analysis to be done when required by the user, without the risk of missing information during image acquisition, since the entire slide is recorded. 

The free NDP.view2 software allows viewing, annotation, and export of scans. NDP.Serve allows the hosting of slides online for viewing via a web browser.

Phase Focus LiveCyte2

livecyte

The LiveCyte2 utilises Quantitative Phase Imaging (QPI) to generate label-free high contrast images for automatic quantification of live cells. The proprietary QPI technology allows the gentle imaging of even sensitive cell lines that would normally be prohibitive of live-labelled imaging. 

The user-friendly software allows real-time analysis of live time-series experiments, meaning users can set up assays and collect fully processed figure-ready data at the end of the run, along with viable cells that can be passaged or processed for further experimentation. 

Phase Focus provide a suite of analysis assays, for tracking a range of metrics in a variety of combinations, with applications in Cell Proliferation and Growth, Wound Healing, Cell Motility, Oncology, Toxicology, Angiogenesis and Stem Cell differentiation.
