Calibration

Calibration > New Optical Configuration

This command is used to create a new optical configuration. It runs the optical configuration wizard. See Optical Configurations for more information.

Name

Displays editable name of the selected optical configuration.

Camera setting

Check this item to include the current camera settings to the new optical configuration.

Use Stored ROI

If you want to include the camera ROI settings, select this option. Status of the camera ROI (ON/OFF) and its size will be set when switching to this configuration.

Channel setup

These settings determine how channels of newly captured images will be named and what color will be assigned to them. The available properties depends on the current camera setup (color/mono). In the mono camera mode, you can either assign the name, the emission length and color to the channel Manually, or leave this task to NIS-Elements (the Automatically option). In such case, information of the light path (emission wavelength) will be used to determine the channel name and color.

Microscope Setting

Check this item to include the current logical devices to the new optical configuration.

Active Shutter

Select a shutter from a list of all available shutters in the pull down menu. If you are running the NIS-Elements in a Multi Camera mode then second Active Shutter item appears.

Used devices

Check all the available logical devices you would like to use.

Objective

Check this item to include the objective (nosepiece position) in the configuration. Select which nosepiece position will be assigned from the drop-down menu.

Finish

Press this button to create new optical configuration and close the dialog.

Cancel

Press this button to close the dialog without creating optical configuration.

Calibration > New Optical Configuration for Fluorescent Probe

This command is oriented on fluorescence microscopy and creates a standard optical configuration. Optical filters and fluorescent probes characteristics are displayed within the window:

Fluorescent Probe

The pull-down menus of this section serves for selecting the fluorescent probe(s) which you prepare the optical configuration for. There are two pull-down menus - probe categories and the list of all probes. Selecting a category restricts the list of probes. You can also use the text Search box to quickly search for the desired probe by its name.

Characteristics of the selected probe appears in the space below the menus and a graph of its emission/excitation efficiency is displayed.

Optical Configuration Name

When you select a probe, the Opt. Conf. Name is suggested automatically. It can be edited. On the right side, there you can select which hardware settings will be included in the optical configuration (Optical Configurations).

Filters

Select the Filters check box to include filter changers settings in the optical configuration. The Turret, Excitation, and Emission pull-down menus become active. When a filter is selected, its characteristics (raising edge, falling edge) are indicated in the graph.

Channel Color Assignment

When you capture a channel using the optical configuration created by this window, a color is assigned to it automatically. However, its value is computed from the emission characteristics of the probe used. Therefore, the channel color may differ from the color you see in live.

How to Extend the List of Probes

To extend the list of predefined fluorescent probes, spectral description of additional probes should be placed to the following folder:

/Documents and Settings/All Users/Application Data/Laboratory Imaging/NIS-Elements /Fluorescent Probes/

  1. Create a new text file for each probe. The file extension is not required.

  2. Insert the tabbed spectra description (see below).

  3. Save the file to the Fluorescent Probes folder.

The name of the text file (with the extension omitted) will be used for the probe name. If the probe name should contain the โ€œ/โ€ symbol, substitute it with โ€œ#โ€ in the filename. It will be replaced automatically. Example: โ€œ6-JOE#pH 9.0.txtโ€ will appear as โ€œ6-JOE/pH 9.0โ€ in the list.

Spectra Format

The text file should contain tabbed spectra - values should be ordered in four columns separated by commas: excitation wavelength, excitation efficiency (0 to 100), emission wavelength, emission efficiency.

Manually, drawing a line of known length

Manual calibration is done by drawing a line of known length to the image. You should have some kind of calibration slide or a ruler placed in the scene.

Choose one of the three modes: horizontal, vertical and parallel lines. Click into the image to place the first line, then the second line appears under your mouse cursor. Place the line by clicking again to define the distance. Select the Zoom on Click option to automatically zoom-in when positioning the line. This helps to precisely define the line position. Pixel size can also be defined if needed. Once both lines are placed, the following window appears:

Enter the known length of the drawn distance, make sure the units are correctly selected and click OK.

Automatically, using stage

(requires: Stage)

If you choose the automatic method, the application will guide you through the calibration process. The Auto method is fully automated. The 4 points method needs your cooperation. Move the stage to the marked points and when you reach the position, click OK. The calibration will be calculated automatically afterwards.

Calibration > Recalibrate Document

This command recalibrates an image, which was already calibrated.

This is done by drawing the line of known length. Edit the pixel size first when needed:

There are three modes: horizontal, vertical and parallel lines. Click into image to place first line, then second line appears on your mouse cursor. Place this line and the following dialog box appears:

Enter a defined length in real units and press OK.
