Traditional magnifying glasses have lenses made from glass. They work by using a curved piece of glass, which bounces the light around so as to make the image appear larger. The deeper the curve is cut in the glass, the stronger the magnification can be.

EKSMA Optics offers Galilean type beam expanders with thin UV FS lenses suitable for femtosecond applications. Fixed Ratio Beam Expanders are designed to increase the diameter of a collimated input high power laser beam to a larger collimated output beam. Fixed Ratio Beam Expanders can be adjusted for the input beam divergence angle to obtain collimated, divergent or focused beam at the output. They feature non-rotating divergence adjustment by sliding lens design.

The strongest magnifying glasses for those with visual impairments are Video Magnifiers, also known as Electronic Magnifiers, or CCTV magnifying glasses. These are much more powerful than the strongest magnifying glasses with lights, and can go up to 50x in magnification. What’s more, the view display on a video magnifier is much larger than the surface area of a magnifying glass lens.

Laser beam expanders for 1064, 532 and 355 nm wavelength. Expansion ratio from 2x to 10x beam expanders and zoom beam expanders with 1x-8x.

The strongest magnifying glasses need a really, steeply curved piece of glass. To get the angles required the glass itself needs to be quite small, otherwise the entire unit would be so big it would be too heavy and unmanageable.

If you’ve ever had a strong magnifying glass, you may have been frustrated by the small lens! Digital magnifiers solve this problem. If you need magnification greater than 20x we would recommend a digital magnifier. They are higher budget, but our customers love them and say they wouldn’t cope without them. They can really help you to get your independence back and enable you to do all the tasks that you couldn’t do before.
