Conventional microscope cameras capture 8-bit color images, displaying up to 256 levels of color gradation.
With the new KEYENCE VHX-5000 Digital Microscope, images can be captured with 16-bit or 65,536 levels of color gradation.
This results in images with 256 times more color information than conventional 8-bit images and increases the number of representable colors by over 16 million times. All of this data is then processed by the VHX, which optimizes the color, brightness, contrast, and texture, and then displays the most suitable image given the object being observed.
Samples that were typically very difficult to observe using conventional microscope systems, such as low-contrast and reflective targets, can be easily imaged in high detail.
In order to capture a 16-bit image, the camera will vary the shutter speed and take multiple images at different brightness levels. While there are 16-bits of information associated with each image, only 8-bits of data can be displayed at a given time. A user can specify which 8-bits of information to display, so that the appropriate feature or detail is clearly visible.
The VHX Series contains KEYENCE's most advanced graphics engine, the REMAX V, capable of rendering RGB components with 16-bit gradation, even while viewing a live image.
This processor has been designed specifically to maximize the capabilities of the VHX functions - speed, resolution, real-color reproduction and operation.
Applications that were difficult to observe with conventional microscopes can now be effortlessly imaged.
The entire target can now be observed with consistent illumination throughout; from dark crevices to areas with overpowering glare.
Structure that have almost no contrast can be observed in detail.
Easily render detailed structural images of targets with low contrast.
Even detailed images of transparent targets can be accurately captured.
Targets with subtle color differences can now be easily distinguished.
