Multi-purpose Industrial LED Bench Magnifier

KFM LED and KFM LED ESD models have a robust all-metal construction with sleek design, a flexible arm and excellent light output. It is suitable for all industrial applications.

The flexibility of the joint between lamp’s head and the arm makes exact positioning very easy. The quality of the LEDs allows for virtually shadow-free magnification and excellent colour rendering.

KFM LED ESD is designed to dissipate static charges as they occur in a controlled manner.

Details

KFM LED round lens bench magnifier is ideal for a variety of precision tasks, including: electronics rework, deburring, sample preparation, dissection, assembly and manipulation.

A flexible, self-balancing shade and fully-enclosed, hands-free neck design is ideal for environments where foreign object debris (FOD) is a concern.

Shadow-free magnification

The quality and positioning of the LEDs across two semi-circular modules allow for virtually shadow-free illumination and excellent colour rendering.

Flexible working positions

Our magnifiers are specially designed to maximize horizontal and vertical movement. They provide significant horizontal reach, and will always stay in the right position without drifting.

The arms are balanced by spring systems which ensure smooth and easy positioning – no knobs to tighten, nothing to adjust.

The flexibility of the self-balancing arm and friction-free joint between the head and arm makes exact positioning easy. The fully-enclosed neck design is ideal for mechanical, electronics, circuit boards, dental and jewellery and other precision applications.

Importance of light quality

Good lighting reduces the risk of health problems, increases safety, and enhances productivity.

Hence great importance is placed on the light quality of our illuminated magnifiers, having powerful luminators with excellent light output. The quality and exact positioning of the light sources in relation to the lens allows for virtually shadow-free magnification and excellent colour rendering capabilities.

Glass lens for superb clarity and comfort

The quality of KFM LED starts with the high performance optical glass lens providing superb clarity. The crown glass lens has a lower refractive index than plastic lens bench magnifiers, which reduces the loss of light in transmission through the lens and therefore less distortion of the image.

Less distortion makes for more comfortable viewing over longer periods of time.

FAQ's

Can I have a higher dioptre lens?

There are two options available 3.5 and 5 dioptre models, please specify which dioptre lens you wish when ordering. The lenses are fixed and not inter-changeable.

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

Generally 3 and 3.5 dioptres provide the best balance between magnification and working distance for more industrial uses.

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 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?

Yes. There is 10% – 100% dimmable illumination control.

What is a dioptre?

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

As the dioptre increases, the lens becomes thicker, making the object look bigger. The higher the dioptre, the more magnification the lens provides. A flat window has an optical power of zero dioptres, 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 dioptre lens = 3/4 + 1 = 1.75x

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