Digital solutions – Developed to be exceptional!
Soft Imaging System’s digital cameras meet the steadily rising expectations being placed on digital acquisition. The 12-bit, Peltier-cooled ColorView II – equipped with FireWire™ technology (IEEE 1394) – is the newest product of this series and is for use in the field of light microscopy.
The ColorView II makes it possible to acquire high-resolution color and black-and-white images, rich in detail and contrast with astoundingly low noise. And the truly astonishing thing is how easy this high-performance camera is to use – just as easy as any regular video camera.

All camera functions are fully operable via the analySIS® image-analytical software. No matter what the actual acquisition conditions, real-time functions ensure that the entire dynamic range is exploited. This ensures optimally balanced contrast and superior image quality.
The ColorView II’s full integration into the analySIS® software provides all capabilities and advantages of Soft Imaging System’s innovative solutions to all challenges of image processing and analysis, ranging from image labeling on to image archiving, report generation and e-mailing and including photo-realistic printouts – all without any need for a darkroom.

High resolution
The ColorView II’s CCD chip has a 2048 x 1536 pixel resolution. This is more than seven times greater than what a regular video camera can provide. The user sees more and measurements can be carried out with even greater precision.
High dynamic range
The ColorView II’s 12-bit dynamic range provides images of 4096 gray values (or 4096 gray values per RGB channel). So what does that mean? It means that images can be acquired that have either very bright or very pale areas. Ultimately, this higher depth of data reflects a greater depth of information overall.
High frame rate
This camera supports three different frame rates. The special “search mode” with a frame rate of more than 25 images per second at 688 x 512 pixels makes finding suitable areas of a sample directly on the PC screen especially convenient. The “focus mode” provides 15 images per second at 1024 x 768 pixels. And thirdly, at the highest resolution – 2048 x 1536 pixels – you’re still getting 5 images per second. This means your focusing can be done in real time and upon image acquisition, you have images of temptingly persuasive quality.
Partial-read out
The ColorView II supports partial read-out. This mode is for setting an ROI which is smaller than the whole image. This means you get a fast preview of this area.
Color binning
In the search and focus mode, the ColorView II uses either triple or double true-color binning. This ensures that the user sees the entire image segment in color while searching or focusing. This guarantees that the user is able to view all images in color independent of the resolution.
FireWire™ Interface (IEEE 1394)
FireWire™ technology guarantees that the ColorView II can be easily and conveniently installed on any PC or laptop equipped with a FireWire™ port. No extra frame grabber is necessary. This also means the user has the enviable option of using more than one camera with the same PC.
Low noise and cooled
A highly efficient read-out technology (Correlated Double Sampling) in conjunction with Peltier cooling of the chip provides images with an optimal signal-to-noise ratio. Chip temperature is maintained at 10° C via Peltier elements. This makes for very low noise, which in turn means that greater detail is visible.
High sensitivity
The highly sensitive CCD elements make it possible to detect even very weak signals. The electronic shutter offers exposure times ranging up to 160 seconds. The ColorView II offers exposure time ranging from 100 µs to 160 sec. Details of your sample that had been impossible to see, become readily identifiable. This is just as true for low-intensity applications as well!
Black-and-white acquisition mode
Furthermore, the ColorView II offers a black-and-white acquisition mode. The resolution of this special mode is restricted to 1024 x 768 pixels. This means you are able to acquire monochrome fluorescence images without having to use a second camera, for example.
Compact design
The ColorView II’s elegantly designed housing is compact and can be mounted onto any light microscope with a C-mount. No additional interfaces or adaptors are necessary. ColorView I’s integration into analySIS® provides numerous advantages.
Real-time functions
ColorView II’s own impressive velocity along with the speed of today’s CPU’s mean that a whole range of real-time functions are available within analySIS®. One of these is automatic contrast enhancement. Others include automatic white and black balance, focus control and histogram display.
Image analysis
An extensive range of text, graphic and editing functions is available for labeling your images. For more extensive examination of images there are specialized filters and professional particle analysis. This ensures that it is easy for you to obtain your results fast and flexibly – and those results are reproducible.
The dark room is history
Get printouts of photographic quality immediately following image acquisition. The need for a dark room or all those film-developing chemicals has gone the way of the horse-drawn carriage. As opposed to using conventional film, you obtain printouts of your acquisitions within minutes – and of photographic quality.
Archiving
A high-performance, networkable, MS-Access-compatible image database is integrated into analySIS®.
All data relevant to image acquisition and documentation is saved along with the images themselves. Texts, sheets, diagrams or additional images can be saved along with images. The entire database structure is user definable (without the user having to be an expert in computer programming).analySIS® has an extemsive range of text, graphic and editing functions for labeling your images.
Automatic report generation
This means quick and efficient generation of single- or multi-page reports of your results – using the images you’ve acquired. All you do is select the images you need from your database or from the images manager and drag and drop them onto your report template. Then your report is completed. Along with the image itself, all information contained in database fields is automatically inserted into the corresponding fields of the template. Reports are generated based on templates that you create yourself according to your own personal preferences and/or according to company guidelines.
The report generator provides you with a broad range of tools for designing your template(s). All documents supported by the docu expansion version of analySIS® can be inserted into the templates – ie, sheets, diagrams, graphs and images. In addition, automatic image scaling, standard magnifications and exporting reports via RTF format are all supported. And then the completed report can be conveniently e-mailed directly within analySIS®.
Efficient interaction: ColorView I and mia
Use the ColorView I in conjunction with the miaanalySIS® add-in and see just how smoothly they interact. mia is for obtaining single, high-resolution, large-area images via the automatic montaging of component images.
This is tremendously useful in the following situation. You’re working with a big object and you want capture all of it at high resolution within one single image. However, the microscope is only capable of showing a portion of it at the resolution desired. No problem. All you need to do is define size and resolution. And analySIS® and mia take care of the rest.
