SWIFT SW150 Compound Monoculaire Studentenmicroscoop met 40X-1000X Vergroting, Glasoptiek, Extra 25X Widefield Oculair, Grof en Fijn Focussen, Dubbele Verlichting, en Draadloze Capaciteit

Bought for my granddaughter . She is nearly 7 and loves it. This is not a toy and she takes it seriously to study things around her

 

This was so easy to use. Keep in mind the power switch is a double throw with center off. Left is bottom light and right is top light. The intensity control works for whichever light is selected. Focus is very easy and clear. You probably will not need to use your glass as I was able to remove my reading glasses and focus perfectly with this scope table lift control.Only the two lower magnifiers were usable. The highest magnifier on the turret was not usable so far and I doubt it will ever be because it is just to strong. This is not a problem with the scope because that is the case with any scope I am, sure. Magnifying to 1000 or even beyond 600 is not usually usable. I am not an expert, but I have heard this from experts. Therefore, any scope you buy with magnification of 1000 or higher is more of a gimmick. I am still giving it 5 stars because the two lower magnifiers are commonly usable settings and work great. I will keep trying the 3rd magnifier and see if anything can come of it, but the second magnifier is so powerful that depth-of-field is very shallow. Therefore, it makes sense the 3rd strongest magnifier will be near impossible to use if not completely so. But again, this will be the case with any scope you buy.It runs on batteries, but plugging in the power supply switches from battery to wall power. There is a mechanical switch that triggers when the power supply is plugged in.A nice effect is that if you focus with the 10x ocular and then switch to the 25x, it pretty well remains in focus. The fine adjust work great. Under the table is a rotating wheel that switch between seven different diameter condenser holes, but it had little effect for me. I would have preferred to rotate between colored filter lenses. I may find some colored plastics and modify this unit to rotate a few colors.All in all, this scope works great. It is not too large and doesn't need to be assembled. Therefore, it can be easily returned to its box for storage. However, it does come with a little cover.It will also accept standard scope cameras in place of the eye piece.

Comprato per una bambina di 6 anni che adora la scienza, non è il classico giocattolo, va usato con un adulto, è un buon prodotto amatoriale , con qualche accricco si può collegare una videocamera all'oculare per vedere le immagini al PC. Dotato di copertura antipolvere, sarebbe utile aggiungere una valigetta per portarlo in giro, altrimenti va riposto sempre nella sua confezione di polistirolo
