Keyence has just introduced its new user-friendly digital microscope VHX-6000 to the German market.

The digital microscope VHX-6000 from Keyence with advanced features has a new multi-lighting function that enables objects to be seen with different illumination views. At the push of a button, all necessary lighting options are stored in a single image. If a different type of illumination is desired to visualise other features, there is no necessity to capture a new image. The lighting can be easily adjusted even after capturing the image as the license-free software allows for its adjustment on any computer.

Numerous lighting techniques such as brightfield, darkfield, transmitted light, polarising light and differential interference observations complete the system.

The dual zoom VH-ZST lens with its magnification range of 20x to 2,000x supports the Keyence mix lighting, which combines bright and darkfields. Also high-resolution RZ lenses enable detailed analysis down to the sub-micrometre range. There are new measurement and analysis functions, such as technical cleanliness/ foreign body analysis, which are based on ISO standard 16232 and VDA 19. An image can be divided into several regions after the total measuring range has been detected and each region then analysed individually. In addition, the latest software offers fast and automatic area measurements and counts. It also offers grain-size analysis, which is based on ISO standard 643 and ASTM E1382.

06/27/2018 - Metrology has become one of the most important elements in the manufacturing sector, with industry experts predicting the metrology market to witness a significant increase in the near future. read...

According to the company, the VHX-6000 also has improvements in real-time depth composition. It provides depth composition automatically and at a push of a button. Moreover, when the XYZ-directions are displaced, a depth-sharpness is still present in the live image. The user only needs to move with joystick to the respective area he wants to view. The VHX-6000 microscope then automatically scans through the focal range of a sample, recognises which areas are in focus and builds a fully-focused image thanks to its high-sensitivity, high-speed CMOS camera, which has a frame rate of 50 frames per second.

All components, namely the lenses, camera, graphics system and object table are Keyence's own developments and designed as a complete system. Furthermore, the motor-driven XY stage now has a wider range and a higher load capacity and its microscope stage can now be moved much faster. The new VHX-6000 digital microscope is distinguished by its high user-friendliness, speed and repeatability.

VHX-6000 is among the Keyence's exhibits at AMB in Hall 7, Booth B70.
