    • Basic, mid and high level models
    • Designed for industrial applications with ergonomic flexible arm technology
    • Large, high quality optics for comfortable viewing
    • High quality crown glass or hard coated plastic lenses, distortion free
    • Perfectly balanced stands, with edge clamp of weighted base.
    • Energy efficient LED illumination, dimming on all models, some with segmenting
    • Ultra Violet (UV) and Electro Static Dissipative (ESD) versions available

Magnification

Choose between 3.0 and 5.0 dioptre models, which equate to 1.75x and 2.25x magnification.  To increase magnification further secondary lenses are available on some models, which can increase power to 10 dioptre (3.5x) for inspecting small areas. Generally 3.0 and 3.5 dioptres provide the best balance between magnification and working distance for most industrial uses.

What is Dioptre?  The convention is to express magnification for bench magnifiers in Dioptre but this can be confusing as many people only understand Magnification. However, it is easy to convert  dioptre into magnification, simply divide dioptre by 4, then add 1.  For example 5.0 dioptre = 5/4 + 1 = 2.25x. So objects viewed through a 5.0 dioptre lense would appear 225% larger than normal.

We are frequently asked for a higher power magnifier, one with greater magnification, but also with a large lens. However, increasing magnification power makes the magnifier less convenient to use as the lens diameter, field of view and working distance all decrease. Usually, bench magnifiers are low power between 1.75x and 3.0x. If you need higher power consider a stereo microscope or digital microscope instead.

Lens quality

Vision-Luxo Wave LensFor the best clarity and sharpness of image with no distortion look for bench magnifiers fitted with crown glass lenses which provide superb resolution and colour rendering.  The exception is Waldmann's latest MLD model that uses a new hard-coated plastic lens which, despite not being glass, offers excellent distortion free viewing with colour rendering Ra > 80.

 

 

Illumination

Bench magnifiers are not just magnifiers with light, but need to be powerful illuminators with excellent light output and good colour rendering capabilities. Look for:

  • Excellent bright and warm light
  • Up to 7,400 Lux* illumination
  • Fully adjustable and dimmable
  • LED 50,000 hour life span
  • Shadow-free circular light sources
  • 3D lighting aids depth perception (certain models only)
  • UV light versions are available for specialist applications

* Lux is a measure of the light intensity over a specific area. 1 Lux is equal to 1 Lumen per square meter.

Arm construction

Vision-Luxo Magnifier ArmOur bench magnifiers are especially designed for maximum flexibility and ergonomic operation. They offer three important head movements, horizontal side-to-side, up and down movement and rotation.

Vision-Luxo magnifiers use a unique spring arm balancing system which allows quick and efficient positioning without the need for stability knob tightening. Result - One handed ‘Move and stay’ operation.
