IFM is an ideal lighter-duty magnifier for low-power inspection. A 22W circle-line fluorescent lamp provides 360° shadow-free illumination and a lamp diffuser cover protects the bulb from damage. The IFM is a smart, economical choice for tight budgets.

IFM fluorescent bench magnifiers incorporate the same design excellence adopted throughout Vision Engineering’s award-winning stereo microscopes, providing maximum clarity, flexibility and stability.


  • 3 or 5 diopter (1.75x and 2.25x magnification) options
  • Choice of secondary lenses to increase magnification to a total of 4.75X
  • High performance glass lens for maximum clarity, precision and comfort.
  • 1143mm (45") or 762mm (30") external spring L-arm with edge clamp or weighted based

  • Lens housed in a stamped steel shade with protective lamp diffuser cover
  • Range of available accessories and mounting options

Our bench magnifiers have a number of accessories to provide the ultimate flexibility and comfort.

Can I have a higher diopter lens?

There are two options available 3 and 5 diopter models, please specify which diopter lens you wish when ordering.The lenses are fixed and not inter-changable.

To increase magnification further there are a number of secondary lenses availble (refer to magnification table in Technical section). 

What is the benefit of a glass lens over a plastic lens?

There are number of reasons that mineral glass lenses provide exceptional clarity and robustness over that of plastic lenses.

High quality glass mineral lens offers less distortion than plastic as it has a better surface form and refraction index, so allowing more light through providing better optical clarity of the image. 

Plastic can be easily scratched and is less durable than glass and can be accidentally melted through contact with a hot source such as solder or splatter as well as being is less resistant to chemical and solvents.

Glass lenses bench magnifiers are usually higher quality than plastic lens versions and are more suited to industrial, scientific and manufacturing applications.

Can I easily adjust the illumination?

There is no adjustment, but the circle-line fluorescent lamp provides 360° shadow-free illumination.

What is a diopter?

A diopter (US) or dioptre (UK), is a unit of measurement of the optical power of a lens or curved mirror.

As the diopter increases, the lens becomes thicker, making the object look bigger. The higher the diopter, the more magnification the lens provides. A flat window has an optical power of zero diopters, and does not converge or diverge light.

It is also important to note that the power of the lens is inversely related to the focal distance (working distance). Meaning, as the power of the lens increases, so the focal distance decreases, making it more difficult to perform tasks with high magnification lenses.

See Mantis Compact low magnification stereo microscope if higher magnification is required.

Magnification is calculated by simply dividing the dioptre by 4, then adding 1.

e.g. 3 diopter lens = 3/4 + 1 = 1.75x

Therefore, objects viewed through a 3 dioptre lens will appear 175% bigger than normal.
