Opticron Folding Metal Loupe Magnifier 10x 23mm (0.9")

Excellent quality

Feels nice and hefty, durable, and does the job. Great for looking at moss up close while on a stroll.

The title says it all. I bought both the 6x and 10x by 23mm versions and disassembled the 6x out of curiosity. This is a air spaced doublet loupe rather than a Hastings triplet. Interesting that this is not noted in the product description, which IMO it should be. Regardless they work well for the reasonable price and the housings seem to be well constructed with good finish and no sharp corners or burrs. If I note any loosening of the stud and Philips head bolt pivot assembly that holds the case pieces together I will use some Loctite to ensure they stay properly assembled.

This is a double lens, not a hasting triplet, loupe, so it has more chromatic aberration and a smaller circle of clarity. On the other hand, it's cheaper. I was going to replace a Hastings Triplet I'd lost, but I found it, so, this one will be a backup.

it works good but it has some distortion. I bought because I misplaced my older 10x loupe (found it a few hours before the new one arrived). quality wise it's decent but like i said it's got a tad bit of distortion and it's a little stronger than my 10x loupe but not by much. I would buy it again though!

In short I have a couple of these, and they were showing there age (over 20 years old) I was looking for a replacement and this was my choice. Very happy, good glass quality and would by it again if I loose this one.

The worst! Fell apart after 2 uses. DO NOT BUY! Junk!!!!

I have a 10x triplet loupe which was cheaper, and I thought this would be better based on the brand reputation. However when looking at printed material I can discern substantially more detail with the cheap 10x triplet. This one is going back to Amazon.

Here is a photo from my phone camera through the lens, compared with the closest macro focus without the lens. It provides good magnification and sharp focus. A little bit of chromatic aberration at high-contrast spots, most noticeable around the edges of the lens and almost eliminated at the centre. The metal case feels sturdy and hardwearing, and it is easily un/folded by hand but then stays in position on its own.

Muy útil para llevar en el bolsillo o en el coche

This has been used on various wild flower walks. Once you get used to using it properly, the results are amazing and well worth the expense.

E' veramente piccolina, la lente ha diametro 23 millimetri, chiusa e' circa 40 mm x 27 mm, aperta 70 mm x 27 mm, spessore 20 mm. Il contenitore e' metallico, di buono spessore (oltre 1 mm) e sembra robusto. La parte nera che alloggia la lente in vetro credo sia in materiale plastico, ma sembra robusta anch'essa. Io l'ho comprata per leggere le scritte sui componenti elettronici, controllare saldature e piste sui circuiti stampati, cose di questo genere. La lente e' da 10 ingrandimenti, va tenuta a circa 3 cm dalla superficie dell'oggetto che si vuole esaminare perche' risulti a fuoco. La distanza ottimale dell'occhio dalla lente e' circa 1-2 cm. A questa distanza l'immagine e' luminosa, praticamente senza distorsioni anche sul bordo esterno ed e' simile come esperienza all'uso di un microscopio di pari ingrandimenti e riempe bene il campo visivo. E' possibile usare la lente anche tenendola piu' lontana dall'occhio, ma maggiore e' la distanza e maggiore e' la distorsione sul perimetro della lente. Praticamente quindi l'area utile si riduce alla sola zona centrale. L'ho provata un po' con vari componenti che avevo sottomano, con circuiti stampati popolati e sono molto soddisfatto. La qualita' dell'immagine e' davvero molto buona. Per me e' comodo poterla chiudere rapidamente e tenerla sottomano senza rischiare di rigare la lente mentre lavoro con qualche altro attrezzo. E non occupa praticamente spazio quando non serve. Ah, c'e' anche un anellino ricavato nella parte in metallo (si vede poco nella foto qui sopra) immagino per poterla appendere facendovi passare un cordino se uno cosi' desidera. Ricapitolando: luminosa, 10 ingrandimenti, va tenuta a circa 3 cm dall'oggetto, sembra robusta, ottima qualita' dell'immagine. Prezzo pagato 25,45 euro.

Perfect for looking at gemstones or other small items closely. Highly recommend.
