Dynascope™ Expanded-Pupil Technology Explained
What is a Lenticular Disk?
At the heart of Vision Engineering's patented Dynascope™ Expanded-Pupil Technology lies a transparent multi-lenticular (multi-lens) disc, composed of numerous lenticules (lenses), which act as independent image forming surfaces with diameters of a few microns each.

 In Vision Engineering's Lynx® Dynascope™, the 148mm diameter multi-lenticular disc surface comprises of over 3.5 million individual lenticules (lenses), each measuring just 70 microns in size. The Dynascope™ disk spins at 3,400rpm to merge the millions of individual optical paths, delivering a smooth expanded-pupil stereo image with a generous depth of focus and a wide field of view.
Optical Parameters
In use, the multi-lenticular disc serves to expand the intrinsic pupil of the system. The resultant image is reflected through the field lenses to the operator's eyes and the high resolution image is projected onto a large viewing area for maximum viewing comfort.
Reduced Operator Fatigue
As operators frequently alternate their views from the magnified object image to the actual object (especially when manipulating parts), the large distance to the apparent magnified image eliminates the need for the eyes to refocus each time - a tangible advantage in reducing eyestrain and fatigue.
In addition, employing a viewer rather than eyepieces permits greater positional freedom for the operator and allows the use of spectacles. Operators who require reading glasses remove them for microscope viewing and must then re-focus at a different distance, which again quickly leads to eye fatigue. Operators with astigmatism fare worse: removing spectacles immediately spoils their vision.
The significant ergonomic advantages contribute to favourable production rates and reduced scrap as the operator sees easier and can work longer without experiencing strain.
Typical Optical Schematics
The primary magnification stage of a Vision Engineering microscope is achieved by the use of a state-of-the-art lenses and corrected internal optics, using a parallel afocal zoom system.
The advantages of infinity focus combined with the enhanced dynascopic technology are increased optical and light efficiency, which in turn deliver greater image clarity and brilliance. The practical implications of Dynascope™ technology include more efficient and accurate user operation leading to improved quality and greater throughput.
