For the LSM 5 PASCAL, lasers with several lines ranging from 405 to 633 nm are available for excitation.

C-Apochromats: Optimized for confocal microscopy.
The intelligent control center
The electronics module houses the main component of scanner control and image acquisition, the digital signal processor (DSP). A trigger interface allows synchronization of external devices (TriggerOut), e.g., a micromanipulator, as well as “remote-controlled” triggering of confocal image acquisition (TriggerIn) by external devices such as a breath sensor.
EC Plan-Neofluars: High contrast for general use.
The stable basis
Depending on the user’s application, several high-end research microscopes are available as platforms for the LSM 5 PASCAL system: Axio Imager, Axiovert 200 M, and Axioskop 2 FS MOT. All of them are equipped with IC2S optics, which guarantee unrivalled image quality, brilliant contrast, and perfect color correction.

Proper Settings Configuration with just a Mouse Click
The success of a microscopical experiment is a matter of correct settings. All parameters of the fully motordriven LSM 5 PASCAL can be selected quickly and correctly, via its intuitive software. The parameters of the experiment – from laser setting to image acquisition – are automatically saved and can be precisely restored whenever they are needed again. So rather than having to care too much about the microscope, you can fully concentrate on your research.
(2+1) detection channels
In the LSM 5 PASCAL, one or two channels are available for fluorescence and reflection measurements, each featuring a highly sensitive, low-noise photomultiplier. XY adjustment of the pinhole is effected through a software-controlled motor; the pinhole diameter can be controlled continuously, as can the intensity of the laser. In some experiments it is helpful to superimpose transmitted-light and fluorescence images to “get the whole picture”. Especially with differential interference contrast (DIC), the optional transmitted-light channel supplies important information about the topology of your specimen.
Clear and easy to use: The software of the LSM 5 PASCAL.

Alternatively, the system falls back on settings made in earlier experiments: the tried-and-approved ReUse function not only speeds up procedures in the lab but also exactly reproduces experimental conditions. Use the Scan Control dialog window to define all scanning parameters, such as frame size (up to 2,048 x 2,048 pixels), scanning speed, data resolution, and scanning direction (uni- or bidirectional). Use the Find function to have the system find the optimum contrast and brightness settings, within seconds of clicking the mouse.

No Crosstalk MultiTracking for Clear Signal Separation Framewise or linewise MultiTracking is an elegant and reliable solution which efficiently prevents interchannel crosstalk between several fluorochromes. Colocalization studies, in particular, benefit from the increase in reliability gained from MultiTracking.
Unique capabilities
The LSM 5 PASCAL allows the user to optimize excitation parameters and detection settings for a single dye signal, and to define and save it as a track. A list of such tracks for independently optimized dye sig-

nals can then be run automatically as a MultiTracking experiment. Unblanking and blanking of the laser lines between the tracks is effected by mechano- or acousto-optical devices. Up to eight fluorescent signals can thus be MultiTracked in a single run, section by section (MOTF) or line by line (AOTF). Due to the selective excitation and detection of the dyes, signal crosstalk is prevented reliably.

MultiTracking is as easy as pie: Select the laser lines, main dichroic beamsplitters and emission filters for each channel in the Configuration Control dialog window. Once compiled, a list of tracks can be saved and activated later whenever needed.

Increased efficiency
MultiTracking is a distinct benefit especially where signals are very faint. Here, you can now use longpass emission filters so as to use the entire emission spectrum of the dyes. The pinhole diameter can be set individually for each track to help balance the signal intensity for the respective dye type or dye concentration. This allows either optimum adjustment for greatly different dye intensities, or to perfectly match the optical slice thicknesses in critical colocalization studies.
Superposition of the images obtained from three channels clearly illustrates the difference: Simultaneous recording results in massive signal crosstalk, which wrongly suggests a colocalization (shown in orange and turquoise). With MultiTracking, the signals from the various channels are clearly separated, and optimum signal yield is guaranteed. The Spectra function displays the selected laser lines and filters in a clear overview. Example of a configuration for detecting Cy2 (green) and Alexa 568 (red) as a MultiTrack with long-pass filters.

Using the LSM 5 PASCAL, you can generate virtual optical sections of any orientation inside the image stack. These virtual sections show you the spatial arrangements inside the specimen, even with structures that are only faintly fluorescent. Integrated measurement functions furnish geometric measurements such as length, angles, circumference or area, as well as densitometric parameters. The Profile function measures signal intensities along freely defined curves. The gray level data are presented in a clearly arranged table.

With freely defined regions of interest (ROIs) you can investigate precisely those structures of a specimen you are looking for. During image acquisition, either the series of images or the intensity curves inside the ROIs or both can be displayed. In ratiometric measurements, rather than waiting until the end of the time series, you can keep track of the results in a separate channel in real time. On-line ratio calculations allow the data to be presented live during image acquisition. The system utilises preset calculation formulae with user-defined parameters.
