The Elliot Scientific MDE269 slide is an ultra-small, triple axis micropositioner with simple adjusters for XYZ linear translation stage applications in physics experiments or optical systems. Variants for vacuum and Low magnetic or indeed a LM-V combination custom build to order are available to match all types of applications.

,I'm convinced that refractive elements for secondary concentrating elements is a much better solution than reflectors. We make the big fresnel lens for solar concentrating. The size of the solar lens is 1040mm x 780mm, Thickness is 3mm. look at the picturer as follow.

We offers a complete range of fresnel lenses sizes and types. We could custom the projection screen according to client requirement. Inquiries are welcome at our offices. please contact:

Note: Surface mating with these micropositioners must be truly flat. Unflat surfaces or overtightened screws will cause the slide motion to be jerky and stiff due to distortion. Dovetail slides, unlike miniature ball slides, are unlikely to be permanently damaged by temporary distortion, as the load is supported on a comparatively large area.

For those who dream of giant solar collectors which can generate temperatures high enough to melt steel, here is a method for building your own Solar Furnace of any size you desire.
