Extremely good loupe x 10 magnification
This loupe is perfect. I am using it for reading jewelry markings, to be able to see serial numbers etched into gold on fountain pens which are entirely invisible to the naked eye. A while ago I bought a 40 x magnification loupe, and the focus was too bad to be able to read the numbers. I thought I'd try this 10 x magnification loup by this brand, as it was recommended to me by someone who has used it. It's perfect. I'm so glad it has LED lights. Without them, I could see there was a serial number but it was difficult to read. After I switched the light on, it became so profoundly clear, with all the visibility and contrast necessary to see a long number with ease. I shall enjoy investigating other small details now using this device. It comes in a lovely leather-like storage pouch, and a small cardboard box with a tool for opening it for servicing. The lens is big enough to see what I need to. It is very easy to use, and the lights operate on and off with a sliding switch.

Feels 'proper'
Feels like a quality bit of kit. Nicely packaged so would make a lovely gift for start. Opening it up, it feels weighty and robust. The light switch is a positive click in each position. The lens takes a decent push to get it out of its protection and it just feels like 20 quids worth; nothing light-weight or flimsy. The lens is clear and with much less fade than my old cheapy loupe I picked up at an antique fayre for a couple of quid. It has a 'leather' case too. Something not many mention, but a real bug-bear for me, the hanging loop on this IS big enough for a small split ring to hang it from; a must if you're in the field or trapesing round antiques all day. Highly recommended. Oh yeah, it magnifies stuff too.

Very good distortion free glass loupe with good strong LED. Recommended!
Very good magnifier. Solidly built with handy little leather pouch. The LED light is brilliant to be able to see clearly what your looking at, I use it almost all the time. Without the LED you need very bright conditions to see properly. The switch is a little fiddly but not a problem. The lens is very clear and indeed made from glass. It only has 3 cell batteries (picture shows four!). I use for detailed wood end grain analyses to determine wood type, perfect for this, would recommend to get this one as a good LED light and a distortion free view is essential.

Very nice quality item
I'm no expert, I just decided that I would like to be able to read the hallmarks on a new ring, which were illegible with hand lens, and started browsing Amazon, as you do. After learning a little about triplet lenses and distortion and reading comments about screws that come loose, I ordered loupe. I have to say it is a revelation. the led light makes the stones sparkle, tiny details and specks of dirt become clear and the hallmark is much clearer. the hinge is not a screw, I suppose the term is a rivet, so it should not come loose with opening and closing. even the little case, which is made of leather, not plastic, seems good value. Also supplied is a little, flat item which is presumably for changing the battery and it is all packed in a nice little cardboard box so could be given as a gift without extra packaging.

Fine but difficult to use
To be honest, it was faffy to get anything in focus with this. I reverted to using the excellent magnifier with light on my phone, which also takes photos of the plants I’m studying.

Good quality triplet lens and LED halo.
Nice quality triplet lens. Metal body. Leather pouch. You can really zoom in on minuscule details such as hallmarks and serial numbers on watch lugs. The LED halo light is very bright and helps visibility if very small details. The UV light is there to verify luminescence of authentic gem stones. Overall very satisfied. There are much cheaper loupes out there that will be all plastic and not as effective. Not sure how long the battery will last or whether it can be easily replaced. The leather pouch is good quality but would benefit from a belt loop for ease of portability. I’d rate this as 4/5 stars. Very good for observing surface damage in watches for example if you’re looking to buy second hand.

Ideal for Geology, Petrology and Mineralogy
This lens has impressive optics. Images are very clear allowing fine details to be seen. The field of view at 21 mm is excellent, enabling a large area to be viewed. It is good for viewing the details of crystals in a rock or individual mineral crystals. Attached photos show a flat polished piece of quartz-microgabbro and a group of grossular garnets. Also a photo of a millimetre ruler plus detail of the same photo. Taken with a phone camera they are not quite as good as what you can see with your eye because when you are using it you make minor position adjustments to view different areas. The white LED light is very useful when there is insufficient light available, although you do get some reflection off shiny surfaces. It should be ideal in shaded spots such as dense forests or on a very dull day. The long wave UV light works fine. It was good to see some calcite crystals glowing pink. As the light is also visible (i.e. not a black light) it is not the same as using far more expensive UV lighting. Construction is excellent with just the right stiffness in the hinge. It has a smart leather case for storage and there is a slot at the top for attachment of a lanyard.

The LED light (and UV) is really helpful
I have still a loupe I use from uni, decades ago, and thought I would treat myself to a new one. I am pleased that I did. The lens itself is nice and clear and the LED light is really helpful for old eyes.

Works great. Great lens. I love the UV light. I'd buy it again. It also comes with a key to open the battery compartment and a nice leather case to protect the loupe.

Come si evince dal titolo, è la mia prima lente "professionale", quindi parlo per quello che so. L'articolo è ben fatto, robusto, accompagnato da una piccola custodia in pelle cucita. Batteria già presente e luce funzionante. Forse quella ultravioletta va usata con poca luce perché è un po' debole rispetto all'altra - si, lo so che gli ultravioletti sono meno forti della luce a tutto spettro - parlo dell'intensità. Comunque sono molto soddisfatto!
