Acquire Tab

The Acquire tab contains controls for acquiring a new image. There is an Acquire tab specific for each type of Instrument that is installed using its Instrument Key (see Application menu for information about importing Keys).

  • If only one Instrument Key is installed, Image Studio™ Software will include that Acquire tab when the application is opened.
  • If more than one Instrument key is installed, choose the desired instrument type from the Instrument Model Selection dialog that appears when Image Studio™ Software starts.

    To change to a different Instrument type, close Image Studio, open it again, and select a different Instrument type from the menu.  

  • If there is not an Instrument Key installed or if you press Cancel instead of selecting an Instrument type, the Acquire tab will not appear during that session.

Channels

Options in the Channels group allow you to select the channel(s) to image and control the scan intensity. Each channel contains an image produced by a specific detection wavelength. Acquisition channels can be viewed overlaid or individually.

Image Studio auto-selected channels

The Intensity fields control the detector sensitivity and affect the band intensity on the image.

  • If the intensity is set too high, the detector may saturate and produce white areas in the middle of intense bands/dots. Saturated pixels are colored blue when the image is displayed in grayscale (see the Display topic for how to display images in grayscale).
  • If the intensity is set too low, the image may not show any fluorescence even though there is adequate signal from the samples.

To set intensities:

  • When Auto Auto Intensity icon is selected (the Auto button will have a blue background, see below), the channel intensities are set to Auto and a wide dynamic range image is captured.

    Auto button toggled on

  • When Auto Auto Intensity icon is unselected, set the channel intensities manually for each channel. A lower dynamic range image will be captured.

    Auto button toggled off

Scan Controls

Use options in the Scan Controls group to set the Resolution, Quality, and Focus Offset. Use Flip Image to automatically show the acquired image flipped top to bottom (useful for microplate images).

  • Scan Resolution— Select 169 µm for most scans. This is the distance the scanner travels between readings. Shorter distances (21 µm) will give higher resolutions that provide more image details but create large image files. Longer distances (337 µm) will give lower resolutions that provide small image files but do not offer fine image details.
  • Scan Quality — Select the scan quality that affects the time and quality aspects of the scan. The lowest quality setting sets the fastest scan speed. Increasing the quality results in slower scan speeds, as more detector readings are processed for a given area. The Lowest scan setting gives the fastest scan time and is appropriate for most scans.
  • Focus Offset — Select the Focus Offset value from the list or enter a value by choosing the Enter Value menu item.
  • Flip Image — When selected the image is automatically flipped top to bottom.
