Large hands-free gooseneck folding desk magnifier, illuminated, 120mm lens

Summary Large hands-free magnifier, gooseneck adjustment, large (120mm diameter) lens. Ref. DT120C Lens size Working distance Mag. Field of view 120mm dia. 250mm (main) 80mm (inset) 2.5X (main) 4X (inset), not 6X as printed on box Main lens 2 newspaper columns X 22 lines of text Inset lens 7 letters across X 3 lines of text Good quality decent-size lens (120mm dia.) for general repairs, swan-neck adjustment, easy to angle the lens. Quick-release button to remove the swan-neck/lens so that it can be used as a handheld magnifier. Lens cap so it can be left on the bench without getting dusty. When comparing these magnifiers on the internet always look at the lens size, this is often not stated, making tiny magnifiers look like serious bench magnifiers. See a large selection of small stand magnifiers. Also see clearance magnifiers. Technical Lens diameter: 120mm Light: three LED lights, white light. There’s also a filter that slides over the light to make it ‘soft’ (orange). Power: 2 AAA batteries or USB. Cable supplied (fits any USB socket*), also mains adaptor supplied. Overall size: 150mm (10inches) tall; 125mm (5 inches) wide; 430mm (17 inches) deep. Item weight (not posting weight): 1Kg Origin: imported from China by QUICKTEST. The Photos The photos looking through the lens have not been enhanced, this really is the magnification. The photos taken through the lens: the blank patch to the right is where the high-power inset lens is the background (small text) is blurred because a camera can't focus on the far-text (not magnified) and near-text (magnified) and at the same time. It's quite easy to Photoshop the photo to get everything in focus...but this photo has not been enhanced. the photo of the lens that shows no text is the underneath of the lens, just to show you the LED lights and the filter. Mag, size, WD Magnification, lens size, working distance. Be aware that lens size, magnification and working distance are connected. This is due to the laws of physics, it is not a choice, this applies to all simple lenses (i.e. not microscopes and telescopes). You want the largest lens? A 150mm diameter lens will give a magnification somewhere between about 1.2X and 2X with a working distance somewhere between 250 and 350mm (10 to 14 inches). Ample room to manoeuvre a large object but not very powerful. You want a powerful lens? 8X magnification will give you a lens of 15 to 25mm in diameter and a working distance of about 25mm (1 inch). You want a very large lens with a high magnification? This is not possible with a simple lens. Consider one of the following: a surgeon’s binocular headband magnifier (it uses two small telescopes not ‘simple’ lenses); a low-power bench microscope (but select the lowest magnification) or a video microscope.
