ZEISS VIVATOME APERTURE CORRELATION MOTORISED INVERT MICROSCOPE CONFOCAL AND EPIFLUORESCENCE IMAGING AVAILABLE..
Aperture Correlation fluorescence microscopy combines the light efficiency of structured illumination with the acquisition speed of a spinning disk confocal instrument and allows you to overcome the limited light efficiency encountered with traditional spinning disk confocal systems where a multi-pinhole array is used to sweep across the specimen.
The bottom port of our invert Zeiss Axio Observer microscope has been fitted with an aperture correlation VivaTome spinning disk unit. The disk is made of synthetic quartz which has been coated with a thin layer of aluminium which is arranged in a structured illumination pattern so that light is either efficiently reflected from the disk surface or passes through it.

Instead of individual pinholes, the VivaTome uses a spinning structured illumination grid pattern to simultaneously image emission light that is reflected (R pathway) or transmitted (T pathway) through the spinning disk side by side on to the sensor of the camera detector. The side by side raw image is split to form 2 individual channel images (T) and (R). R image is mirrored (horizontally flipped) and then overlayed with the T channel image. The pixels in each channel image are co-registered with zero pixel shift. The overlay image is then split into 2 individual channel images, Treg and Rreg. The subtraction of these 2 images from one another (using a K weighting factor of 1 applied to the Rreg image) will form a confocal image whereas addition will generate a widefield image.
You can manipulate the K weighting factor (0-1) to alter the mix amount of confocal and widefield information present in the final image formed.
The microscope also has X, Y and Z motorised capability so various image recording modes can be easily configured (e.g. single or multichannel epifluorescence time lapse imaging in 2D or z stack 3D multifield imaging. The microscope also has Definite focus fitted to compensate for thermally induced z focus drift which can be problematic when recording time lapse images over lengthy time periods.
For very low fluorescence light emission detection, a Photometrics Evolve 512 EMCCD camera has been fitted to the left hand side microscope port for FRET, BRET & multi-epifluorescence imaging. Colibri LED's which allow µsec excitation light switching (µsecs) are used to minimise photobleaching when performing conventional multi-fluorescence or FRET experiments where large image data sets are TTL trigger streamed via a SVB1 trigger breakout box directly on to the hard drive every 5-30 msecs with precise precision. EMCCD camera has been fitted to an image splitting device to record Donor and FRET channel images simultaneously. Image splitter can also be used to record BRET. Acquisition software used to record images is Axiovision 4.8.2.

NIKON ECLIPSE TE 2000-E EPIFLUORESCENCE IMAGING MOTORISED MICROSCOPE.
NIKON ECLIPSE TE 2000-E MICROSCOPE.
This invert configured microscope rig has motorised Z control and can be operated in multiple configurations which allows users to perform single or multi epifluorescence experiments at high speed. Excitation fluorescence over the wavelength range from 320 to 650 nm is rapidly generated from a Cairn OptoScan monochromator and a 10 position emission filter wheel fitted to the left hand side port of the microscope is used for optimal detection of blue, cyan, green, yellow and red monomeric fluorescent proteins or fluorochromes. Photobleaching of samples is minimised by rapidly shuttering ( - 1 msec) the output slit of the monochromator. Emitted fluorescence signals are sequentially detected using a high resolution Hamamatsu ORCA FLASH 4.0 LT+ CMOS sensor camera coupled to an emission filter wheel. Alternatively, fluorescence emissions can be detected simultaneously with no time delay using an ORCA FLASH 4.0 LT+ CMOS camera coupled to a Quadview 2 image splitting device (Mag Biosystems) situated on the microscope's bottom port. The microscope has a built in linear z encoder for high precision acquisition of multi-fluorescence z stacks over time (4D). Rapid exchange of test ligands to cells grown on round glass coverslips is achieved by using an open cell perfusion chamber coupled to 2 solenoid valves via a 4-channel peristaltic pump. Acquisition software used to record multichannel images overtime is Metamorph version 7.8.13 and time lapse ratiometric imaging (e.g. Fura 8 calcium or REDOX potential imaging) can be performed using Metafluor version 7.8.13.
