With the release of ChromaCal™ 2.0 (free for existing ChromaCal™ customers), Datacolor also introduced the ChromaCal™ Macro Calibration Target ("ChromaCal™ Target"), a color target specific to reflected light imaging of macroscopic samples. The ChromaCal™ Target is a printed, matte, color matrix available in two standard sizes (10 cm x 7 cm and 5 cm x 3.5 cm). In addition, Datacolor is offering a unique service – high-quality, custom-sized, printed color targets are available upon request.
The ChromaCal™ Image Calibration software requires a ChromaCal™ Color Calibration Slide for Brightfield Microscopy (sold separately, product #10-2010 or #10-2110) or a ChromaCal™ Macro Calibration Target (sold separately, product #10-2500 or #10-2550).
New! EZ Image Prep – a feature now included within the ChromaCal™ Image Calibration Software.
We heard your frustrations about poor image quality from your digital microscope cameras. Often times white balancing is off, or you want to create a montage of images for a report and the backgrounds are different shades. In this condition, you can't include these images in your reports or submit them to journals, right?
Sure, there are steps you can take in Adobe Photoshop and other image editing software to try to correct. But,
- Can you do it in one simple step?
- Can you easily perform it in batch mode?
- Can you perform it without having to select the "right" area of the image?
And, what often happens in image editing software when you try to replicate a white balance adjustment and apply it to other images? The results are inconsistent and you are forced to correct each image one-by-one.
Introducing EZ Image Prep™, a new feature now included within ChromaCal™ Image Calibration Software. EZ Image Prep is the only scientific solution to automatically white balance and match brightness in color brightfield images in a single-step batch process. And unlike color calibration, there's no need for a calibration slide.
EZ Image Prep is also "EZ" to use. Simply choose the EZ Image Prep option, select the folder containing TIFF or JPEG images for processing, specify the destination folder, and Process! You'll agree that there is no easier nor more powerful tool than ChromaCal™ to objectively correct your images.

The Datacolor ChromaCal™ color calibration system for optical microscopy provides a color profile foundation from which images can be more easily compared and analyzed. Working with your existing microscope and imaging system, the calibration system fits easily into the imaging workflow – simply acquire an image of the calibration slide (required, and available separately) and using the proprietary software, apply the calibration to your specimen images. Your original files are preserved, and a complete audit trail is saved in the metadata of the calibrated images. Better consistency. Higher confidence. Color integrity for better decision making.
Includes both the image calibration software (a license to install on one workstation) as well as the monitor calibration set (a license to install on three workstations). Additional workstation installations can be purchased and activated directly through the software.
Datacolor ChromaCal™ Calibration Slide for Brightfield Microscopy
The Datacolor ChromaCal™ brightfield calibration slide is a unique, precision-engineered tool that is used in conjunction with the Datacolor ChromaCal™ brightfield microscopy calibration system and your microscope to establish a baseline color profile that is unique to your imaging session. The process is simple - acquire your specimen images and an image of the calibration slide. Using the proprietary Datacolor ChromaCal™ software just click to apply the color profile to your specimen images for a standardized approach to seeing colors.
The Datacolor ChromaCal™ Color Calibration Slide is designed exclusively for use with the Datacolor ChromaCal™ Color Calibration System for Optical Microscopy.
Each Datacolor ChromaCal™ slide is uniquely identified and corresponds to a specific color measurement file associated with the proprietary Datacolor ChromaCal™ chip at the center of the slide. The measurement file contains information that is utilized by the Datacolor ChromaCal™ Color Calibration System when calibrating brightfield images.
Located on the Datacolor ChromaCal™ chip are the following:
- One larger color matrix consisting of 20 color circles in a 4 x 5 configuration. This matrix is generally intended for magnifications up to 40X.
- One smaller color matrix consisting of 20 color circles in a 4 x 5 configuration. This matrix is generally intended for magnifications above 40X up to 100X.
- Numerous location lines pointing to a circle surrounding both color matrices. These are meant to assist in locating the color matrices.
- In the upper left-hand corner of the chip there is a 4 x 4 micrometer grid consisting of 250µ divisions. Within the lower right-hand division is a 10 x10 sub-grid with 25µ divisions. This micrometer grid is unrelated to the color calibration system but is provided as an additional value-add.
The Datacolor ChromaCal™ slide is not suitable for use with oil immersion objectives. The Datacolor ChromaCal™ slide should be handled with care.
The Datacolor ChromaCal™ brightfield calibration slide is sold separately, and is required for the Datacolor ChromaCal™ Color Calibration System.
Datacolor ChromaCal™ Monitor Calibration Set
Monitor Calibration Sensor in use
The Datacolor ChromaCal™ monitor calibration set uses a precision color sensor to ensure a consistent and standardized color profile on any computer display. With monitor calibration, your images will look the same on the display by your microscope, at an analysis workstation, on your laptop, and on a colleague's display whether down the hall or across the ocean. In contrast, just look at the variability between televisions on display in an appliance store.
Includes monitor calibration sensor, software and license to install on three workstations. Additional workstation installations can be purchased and activated directly through the software.
Good microscopy practices are essential to achieving quality images. Here are a few things to remember. These steps won't guarantee perfect images, but they reduce the number of variables to address in downstream image analysis.
- Always be certain to clean the microscope of dust and oils as these can create artifacts and aberrations.
- Establish Koehler illumination as a matter of routine - this practice sets an illumination baseline for consistency and reproducibility.
- Use a scientific-grade camera (CCD or CMOS), not a consumer camera, for imaging. Scientific cameras are designed for sensitivity and the magnifications employed by microscopes.
- Always white balance the camera. Simply move to a region of the slide where no specimen is located (e.g. white background) and choose white balance in the camera software, imaging software or even by pressing a white balance button on the camera head itself, if present.
Macroscopic imaging ("macro imaging"), in broad terms, is imaging where the specimen is generally large enough to be visible with the naked eye. Most specimens in this environment are not transparent, rather opaque; color, therefore, is imparted from the light reflecting from the specimen itself. Macro imaging is widely used for documenting specimens prior to further analysis using microscopic techniques. Specimens can include plants, insects, animal tissue, human tissue, crime scene evidence, geology samples, just to name a few. Regardless of the specimen type, as a researcher / investigator you want your digital images to accurately represent your specimen time and time again.
Macro Calibration Target, 10 x 7 cm
Imaging requires a combination of optics, lighting, sensors and techniques that together form the color representation of the actual specimen. Just as your family photos can look different under various lighting conditions or with different cameras, so too can macroscopic images depending on imaging equipment and imaging conditions. ChromaCal™ standardizes the color in your digital macroscopic images so that they are rendered accurately and consistently.
ChromaCal™ works with your specimen images, so it can be used with practically any macro imaging system you may use. And with ChromaCal™, there is no need to change your imaging workflow. Just capture an image of the ChromaCal™ Macro Calibration Target during your imaging session along with your specimen images. The ChromaCal™ Image Calibration software uses the image of the target to standardize the color in your specimen images.
Macro Calibration Target, 5 x 3.5 cm
With ChromaCal™, your images will have
- Enhanced Color Definition to reveal details
- Consistent color for comparison
- Accurate color for evaluation
