SANXO – Scope HD U4: Versatile Industrial microscope

The digital microscope can be optimized to display torsion free magnified images of the object while having the largest possible working distance for the operator.

• Sharp live image, high resolution
• Easy to use with a single mouse
• Fast focusing, dimensional measurements and 3D imaging
• One click documentation and QR or DTM identification
• Image and Data saving on SSD or on network drive

In use, the application offers basic functionality such as digital zoom and pan, real-time image enhancement and image saving (local/remote device). Using the calibration feature, distance between two points displayed on the screen can be measured using either pixel units or calibrated real-world units. The basic and advanced functions as well as the settings can be accessed by right-clicking anywhere on the screen (see image below).

SANXO – Scope HD U4 is a reflected light microscope, because it uses the reflected beam of the incident light. Ideal to inspect opaque samples, anything that is nontransparent. The SANXO digital microscope performs all the tasks of a traditional compound microscope with the benefits of digital image processing.

The system provides two focusing options, which can be selected and configured in the Settings -> Autofocus tab.In Classic mode, the focusing is triggered by a doubleclick on the target image part. Fast and accurate presets are available. In Continuous mode the focusing takes place automatically in the center of the screen.

The camera stand allows the user to use different working distances very easily by moving the camera closer or further. If the object distance is fixed then the user still can use the real-digital zoom by scrolling the mouse wheel. Using the digital zoom the image is equally very sharp and clear on the full HD resolution LCD thanks to the very good 18 Mpixel camera.

Use the mouse wheel to switch between the zooming profiles. The zoomed area will always be centered to the current position of the mouse pointer. An overlay graphic on the top right corner provides information on the current size, number and location of the zoom state.

If the currently active profile only shows a section of the camera sensor's image, then the currently shown part becomes movable. Again, an overlay on the top right corner of the screen gives the user feedback on the current state of the pan.

The 6mm thick Base Plate is painted metal, the pole is standard 40x40 ITEM aluminum profile, the camera holder and the case are painted aluminum and the LCD and mini-PC holder is painted sheet metal. The base plate is covered with a 2mm ESD rubber mat. The rest of the parts of the system are EC complied standard products.

The stand has adjustable holders for both camera and monitor that enable influencing imaging attributes, such as the camera distance, and operating ergonomy. The monitor can be tilted to get the best view angle for the user. Choice of lenses dictates many properties of the setup as the specifications such as focal length and aperture range ultimately define angle of view, magnification and depth of field. The application offers basic functionality such as digital zoom and pan, real-time image enhancement and image saving (local image folder/remote USB memory stick device).

Measurements can be done easily. Using the calibration feature – one click calibration – the distance between two points displayed on the screen either pixel units or calibrated real-world units.

There is an optional autofocus function that uses the electronically tunable lenses of the Swiss Optotune company. The focal length of the electrical lenses is tuned within milliseconds by applying a control. The Optotune lens can be paired with certain fixed focal length lenses (it does not work with all kinds of lenses). In some setup the Optotune lens is used in between the camera and the fix focal lens and in other setup it can be used as a close-up lens.

The SANXO-Scope HD provides video recording. The resolution and the framerate can be adjusted in the settings. To start or stop the video recording, simply click the appropriate icon in the right-click menu.

The SANXO-Scope HD offers the High Dynamic Range Imaging function.
This function highlights the details in the darker part of the image (typically if the details are in the shade) or reduces the shiny saturated bright part of the image. There are two HDR functions available. One of the functions is optimized for speed and the other is optimized for image enhancement.

Fast focusing in milliseconds: New approach of focusing makes much faster focusing by applying the Map based focusing method. When the object is fixed, the algorithm calculates beforehand a map of focus points. Then by moving the mouse pointer in the screen the image gets focused in milliseconds under the mouse pointer.

Super Imaging (Hyperfocus image): The tunable lens brings add-on features for the user. Using the so-called image stacking technique and the HDR (High Dynamic Range), a big depth of field HDR image can be generated using the SANXO-Scope HD. Also a 3D mesh surface is generated which gives better understanding and a clear visualization of the object to be checked.
