Mantis ‘Spatial Imaging’ Eyepiece-less Technology

Vision Engineering Ltd has a proud history of optical design innovation, holding world patents for a number of optical techniques which improve optical and ergonomic performance of stereo microscopes.

Mantis eyepiece-less 3D optics

Since its introduction in 1994, Mantis stereo microscope has become the accepted standard for ergonomics and high performance magnification.

The eyepiece-less optics of Mantis removes the need for the eyepieces of a traditional stereo microscope, providing users with the same ease of a use of a bench magnifier, but with much greater magnification capabilities.

Users can ever see ‘around’ the subject when they move their head side to side. Really, you need to see it to understand the WOW factor!

Ergonomic benefits of Mantis eyepiece-less technology

Ergonomics of body position
Using a Mantis stereo microscope is ergonomic. Mantis has unrivalled freedom of head movement, plus an ergonomic working position, unlike traditional microscopes, which need to be adapted to be less uncomfortable, more ergonomic.

Optical ergonomics
Sitting back from the 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.

Practical benefits of Mantis

The eyepiece-less optics of Mantis inspection microscope provides superb 3D imaging and unrivalled ergonomics. But businesses choose Mantis because they know its unique ergonomics make their operators more efficient, more accurate and more productive. So the operator benefits and so does the business.

Mantis ‘spatial imaging’ eyepiece-less technology

Mantis employs ‘spatial imaging’ optical technology, which can be applied to lower magnification applications, removing the need for microscope eyepieces.

With a traditional stereo microscope, the image being viewed exits the microscope eyepieces as intense, narrow beams of light. Users must precisely align their eyes to view the stereo image.

Illustrating the light paths through the Mantis stereo microscope

Although Mantis does not look like it, Mantis is in fact a true optical stereo microscope. Two separate light paths pass through the patented Mantis optics, exiting the single viewing lens as twin (stereo) light paths.

The large diameter of these light paths exiting the viewing lens means that users do not need to precisely align their eyes to see the subject. This makes looking through a Mantis an entirely natural experience, just like looking through a bench magnifier, but with magnification options up to 20x (with Mantis Elite).
