Multispectral cameras have been available in the market for many years but the calibration process, as well as the techniques for changing material sizes whilst maintaining consistent images that can be stacked and analyzed efficiently, has been a challenge and created significant overhead.

Phase One has worked with specialists on MSI projects over years. Based upon this experience and learning, we have devised a flexible and easy to handle, yet robust MSI solution with a workflow based on best practices.

The Rainbow capture process is fully automated: simply position the subject matter and press ‘Capture’. The full stack of captures are then made with automated focus, automated “flattening”, automated exposure normalization, and automated alignment to deliver the perfect stack, again and again - with perfect repeatability and stability. 

The Rainbow MSI software controls all the elements – focusing the camera, moving the filter carousel on the filter wheel, turning the lights on and off in the correct order and timing, aligning the images, and finally creating the perfect stack.

The iXG 100MP Wide Spectrum camera employs a high-resolution color accurate CMOS sensor and advanced focusing to deliver sharp, reliable and repeatable results through the entire sweep of the light wavelengths involved. 

The Wide Spectrum RGB sensor is tailored for multispectral work, with the added benefit of being able to also do normal digitization work “Do it once, do it right”. Just attach the included IR/UV-cut filter to the magnetic holder of the lens, and you are good to go, following Metamorfoze, FADGI and ISO color standards.

The CMOS sensor provides a responsive live-view for quick and safe positioning of subject matter.
To keep out stray light, the camera comes with a custom lens shade tube mounted on the filter wheel.

The iXG 100MP Wide Spectrum camera comes with 72mm and a 120mm lenses and extension tubes, all suited for the wide range of MSI imaging tasks, as well as normal flat copy digitization work. 

The RS leaf shutter of the iXG camera guarantees 1 million actuations. Working with the electronic shutter of the iXG camera gives you infinite durability. The precise focusing mechanism of iXG measures distances accurately, and provides for Auto PPI functionality, which makes digitization work at different resolutions quick and easy.

The filter wheel can hold up to five filters. It is configured to support the filtering needs of accurate visible imaging and luminescence imaging, which fits many applications, including the CHARISMA standard manual.

The carousel, which holds the filters is removable and can be configured with any 2” filters for future scientific applications. The factory capture settings can be adjusted to suit different filter configurations. To support different MSI applications, you can simply work with two or more filter carousels.

Rainbow supports two types of LED lights for a wide range of applications:

• Multiband DedoLight, delivering narrowband UV, broadband visible light, broadband and narrowband IR. This light is often used for MSI applications related to Art Conservation and to Police Forensics. Recipes for the capture of images following the CHARISMA standard manual are included.
• Narrowband EurekaLight, delivers 16 narrowbands of light from UV, through visible to IR. This light is often used for MSI applications related to Document Readability.

The Rainbow MSI solution can be tailored for a wide spectrum of applications. The Phase One Expert team is ready with customer guidance to configure the best solution for a given application. Advice is backed up with online demonstrations and sample imaging from the Phase One MSI demo center in Cologne, Germany.

For feasibility studies, smaller projects, and operational support, Phase One offers workshops in which specialists can take the customer through the basics of MSI, and the capturing of relevant samples, directed at the MSI projects in question.
