Information on the Nikon A1R Laser Scanning Confocal with DS-Ri1 CCD camera
The Nikon A1R laser scanning confocal is a research grade confocal microscope capable of high resolution imaging.
It has three solid state lasers (405nm, 561nm and 640nm) and a multi-line Argon gas laser (457nm, 488nm, 514nm).
The unique hybrid scan head has a galvano scanner for high resolution imaging and a resonant scanner for high speed acquisition. The resonant scanner allows high-speed imaging ranging from 30 fps (512 x 512 pixels) to 420 fps (512 x 32 pixels), and the galvano scanner features a maximum scan rate of 4 frames per second at 512 x 512 pixels. By employing a hexagonal pinhole, higher brightness than that of a circular pinhole is achieved.
The A1R confocal has two detectors. The “standard” 4 channel hybrid detector has two GaAsP PMTs and two normal PMTs. The spectral detector has wavelength resolutions of 2.5, 6, and 10 nanometers, and a 32-channel multi-anode photomultiplier. Spectral unmixing allows separation of closely overlapping fluorescence spectra and the elimination of autofluorescence. Real time unmixing can be applied during image acquisition.
The Ni-E motorized microscope is sited on TMC vibration isolation table. The microscope has two dry objectives (10X Plan Apochromat Lambda; 20X Plan Apochromat Lambda), two water immersion objectives (40X Apo LWD WI λS; 60x Plan Apo VC WI) and one oil immersion objective (100X Plan Apochromat Lambda H Oil, N.A. 1.45, W.D.0.13mm). Fluorescence filters are longpass: V-2A (Ex 330-380, DM 400 BA 420); UV-2A (Ex 380-420, DM 430 BA 450); B-2A (Ex 450-490, DM 505 BA 520); G-2A (Ex 510-560, DM 575 BA 590).
The microscope has a zooming port and DS-Ri1 colour cooled digital camera for widefield (brightfield and fluorescence) imaging. An additional GFP band-pass filter is available for widefield imaging. The NIS-Elements C control software platform incorporates visualization, image analysis, processing and data management.

Information on the Olympus LEXT OLS5000 Profilometer
The Olympus LEXT OLS5000 is a laser confocal microscope designed specifically to measure shape and surface roughness of samples at the submicron level.
It is a complementary tool to that of AFM which is traditionally and predominantly used for high resolution height and surface roughness measurements of much smaller areas. The instrument utilises a 405nm violet laser and a pinhole aperture much the same as traditional confocal microscopes, with the addition of a MEMS resonant scanner used for XY scanning of the UV laser for low distortion and aberrations.
When measuring height of the sample, the microscope acquires multiple confocal images through a Z range defined by the user. Based on focus position (Z) and detected light intensity, light intensity variation curves are created for each pixel. Following this a height information/image can be reconstructed, along with an “extended” image which is an image of the sample surface in which the entire surface is in focus.
- Sample sizes up to 100mm high
- 100mm x 100mm motorised stage
- 5x, 10x, 20x, 50x LEXT normal WD objectives, 20x, 100x long WD objectives
- DIC option
- 4k x 4k resolution of scanned images
- CMOS colour camera for optical image
- Height/Width Accuracy: measurement value +/- 1.5%

- Providing sample can fit onto stage and doesn’t exceed weight limit (2-3kg), the full range of samples including but not limited to biological, metallurgical, and geological can be analysed.
