HSL 40x-2500x Compound Binocular Microscope for Adults Professional,microscopes for Student Educate,Biological Microscope LAB Micro Scope microscopio 1000x 400X

Me gustó que es prácticamente un microscopio profesional, los lentes oculares y objetivos, los tornillos de mover la platina y los de enfocar, el condesador y el regulador de la luz funcionan genial. Al principio no lograba enfocar con el objetivo de 40x, pero con el uso ya funciona bien.

My girl is taking science, and she likes microbiology. She was complaining about her older one, and it was dated, so I went looking for a newer, more powerful one for her. I found this one with very nice specs and good power, and I had to get one of these. I was not disappointed; this one has worked out great. First off, very easy to set up and use. I liked the instructions, and they were complete and very easy to understand. It was very easy to set up the various optics, and light adjustment was very easy as well. Secondly, it works great. I like the power, I can really get close, and my girl just loves it too. She can see so much more than she could with her lower-powered scope. I also like how it comes with a large number of glass slides and samples, and they pop in perfectly every time to the scope's bench. Lastly, it is easy to travel with. I like how the travel case is well cushioned, holds everything, including all the accessories, and has a nice carry handle too. No cons, it really worked out great for me, and I am very happy with the purchase.

I bought this to use at home for fun. I'm a biology major, and this microscope is nearly the same quality as the ones we use in our labs.Pros:The price is very reasonable.Includes 10 prepared slides, 50 blank sides, and 100 slip covers.Metal construction.Includes foam-lined case for travel/storage.Has 4 objective lenses.Pretty good optics.Cons:The prepared slides are...okay overall. A few are good, a few are meh.The 25x oculars blur the image.Stupid USB power cable that is too short.Single light source.A pitiful amount of oil is included (the picture is accurate).Additional thoughts:Many manufacturers include higher-power ocular lenses to market a higher magnification power. Adding a higher power ocular is similar to zooming in on a picture you took with your phone: you'll get a closer look, but since it doesn't increase resolution it appears blurry the more you zoom. 1000x total magnification is the upper limit due to the wavelength of light. To achieve a clear 1000x magnification with this microscope, you need to use the 10x ocular and 100x objective, with a drop of immersion oil on both the top of the slide cover and the lens itself. If you don't use oil, you will get a blurry image due to how light refracts through the air. The oil fills the air gap between the slide and lens which provides a clearer image.

We bought this microscope for our farm. It looks like it is a great microscope so far!! Shipping was very fast too. It is heavy duty. Looks nice and is very easy to use.
