Dynascope™ Eyepiece-less Technology
Formed in 1958, Vision Engineering Ltd has a proud history of optical design innovation, holding world patents for a number of optical techniques which improve microscope optical and ergonomic performance.
When first developed in the mid 1970’s, Dynascope™ multi-lenticular (multi-lens) technology was an optical revolution, introducing eyepiece-less microscopy to the world.
Since then, the technology has been continuously developed, providing users with a highly ergonomic and user-friendly alternative to traditional eyepiece microscopes.
Dynascope™ eyepiece-less microscope design
An ergonomic microscope is not only more comfortable and less fatiguing, but more importantly, is also much easier to use. Additionally, optimal operator ergonomics minimises the risk of repetitive strain-related injuries. A happy worker is a productive worker.
Ergonomic benefits of Dynascope™ eyepiece-less technology
- Ergonomics of body position Dynascope™ eyepiece-less optics provide unrivalled freedom of head movement, plus an ergonomic working position, unlike a traditional microscope, which needs to be adapted to be less uncomfortable, more ergonomic.
- Optical ergonomics Sitting back from the microscope viewer allows ambient light into the eyes, eliminating eye strain. Users also have much better peripheral vision, so hand-eye co-ordination is easy, plus they can wear glasses, if required.
What is a Lenticular Disk?
At the heart of Vision Engineering’s patented Dynascope™ eyepiece-less technology is a spinning multi-lenticular [multi-lens] disc. On the surface of the disk there are more than 3.5 million individual lenses (known as lenticules), which act as independent image-forming surfaces. Each individual lens has a diameter of just a few microns (1 micron = 0.001mm).
The multi-lenticular disk spins at high speed to merge the millions of individual optical paths into an aberration-free, high-clarity image.
How does it work?
With a traditional ‘eyepiece’ microscope, the image being viewed exits the microscope eyepieces as intense, narrow beams of light (approximately 3mm in diameter). Users must precisely align their eyes to view the image.
The role of the spinning multi-lenticular disc is to expand the diameter of the “eyepiece”.
With Dynascope™ ‘eyepiece-less’ optics even though there are no “eyepieces” as such, there are still two separate light paths, which pass through the patented optics, exiting the single viewing lens as wide twin light paths, approximately 40mm in diameter.
The large diameter of these twin light paths exiting the single viewing lens means that users do not need to precisely align their eyes to see the subject. This freedom of movement significantly improves user ergonomics, reducing neck, back and eye strain, while making operators more efficient and more productive.
Practical applications of Dynascope™ eyepiece-less technology
By removing the need for microscope eyepieces, there are number of significant benefits, which have contributed to the continued success of Dynascope™ eyepiece-less technology.
1. Dynascope™ eyepiece-less microscopes are really easy to use.
- No fiddling with eyepieces. Just look into the viewer.
2. View images in stunning detail.
- Ideal when quality matters. High resolution, high contrast images mean you can see what you want to see in intricate detail.
3. Exceptional ergonomics.
- Traditional eyepiece microscopes can be adapted to be more ergonomic (less uncomfortable), but eyepiece-less microscopes are the current pinnacle of ergonomic microscopy.
- Resulting improvements in operator productivity and quality of operation are major considerations for many companies when choosing a microscope.
