A4 Fresnel Lens in Frame

£ 4.99
The same lens as our 361.OMF, but framed in black plastic with a handle on one side for use as a large magnifying glass. Caution: can also be used as a burning-glass!
A Fresnel Lens is a type compact lens originally developed for use in lighthouses. Our Lenses are spherical, designed to offer a magnification of 3x, with ring shaped segments that focuses light towards the centre of the lens. Towards the edges, there will be a distortion of the image caused by diffraction around the perimeter. All our lenses will produce a sharp image in the centre, albeit not as clear as their spherical glass counterparts.
