Does this come with the Oil immersion dark field lens. I need this for live blood analysis. What is the least expensive microscope available.

it comes with an oil Immersion 100X lens and a Dark field Condenser I have used the 100X lens some and it seemed to work. The dark field is interesting seems to work only with the lower lenses but that could be my inexperience.

Good question, i use it for the same reason. As for its function its a really small scope, so steady hands and good eyes(and patients) are required. It takes a little time to focus it but it does allow you to see when your trichs are ready. For the price its worth it but if you can afford a bigger better quality one i would go with that. The built in light works well though. The over all size of is a little bigger than a large thumb (if that helps at all).

I have the 100x, 200x, 400x eyeclops. The only power i like to use is 100x. The area you are looking at is so tiny that 200x or 400x is too much power. I have a hand held microscope that is 30x, and actually that is the amount of power that is perfect for the viewing area. I ordered the handheld from Educational Innovations. Their online is www.teachersource.com. The first 30x I bought at Radio Shack, but last time I checked they didn't sell them anymore, so I bought a 100x which I didn't like nearly as well. I found the eyeclops at walmart for $20 in the discounted toys. and once again i like the 30 power from teachersource better.

It is focused. I found the magnification to be pretty good and clear for such an inexpensive price. The only thing that I am disappointed with is that with normal use, it seems to pick up a lot of scratches and smudges easily, like the material is too soft.

from what I can see, the WD-60737 has "Improved Dark Field Imager", and "Improved SharpEdge". Otherwise they are the same. Unfortunately, I have not seen these side by side to see if this makes any noticeable difference.

TVM,Thanks for the heads-up on the Sigma. A popular photo mag just this month had a review on a Sigma lens - 18mm/250mm. They gave it a big thumbs up so I'll keep checking up on Sigma for quality and suitability/cost-effectiveness for the T1i. I'll already start some reading up on the 150mm/500mm. BTW - that "500" # sounds juicy. Per Tech's comment (and I educated myself more on what he was talking about) what with a 1.4 or 1.6 mag ratio that 500mm max zoom should be more like in the 700's. I guess that means a quality tripod (read "triple digits") is in the cards too. TVM,Thanks for the heads-up on the Sigma.

The microscope has course and fine focus adjustments. I verified this on my microscope today.

It comes with two eyepiece sets. I don't see a mm setting. One eyepiece says WF 20x . The other eyepiece says WF 10x/18. I did a little research online, and apparently /18 means 18mm. I'm not sure what the 20x eyepiece is. Until my son because interested a couple years ago, I hadn't used a scope since my college biology GM course; and now I'm learning along with him. I suspect life science majors, grad students, and professionals will need to buy better eyepieces. But these have been great to show my son prepared slides and teach him to be aware of a microscopic view of our cosmos. Hopefully our interests will lead us someday to considering better eyepieces in a year or two. But, if you're looking for more now, you may need to budget that into their purchase better eyepieces. Or you can contact the business and see if they would replace these eyepieces, add better ones, and for what price. This has been my only business with them, but they were remarkably attentive and responsive to this novice user.

sorry, can`t help you on that one, I did not order the lens, and I find it OK the way it gives me some perifery lighting. I'm more concern about battery life at this time, after a couple of months batteries last 2 hrs less than at the beginning

Yes, it is a normal microscope. The USB digital camera is optional and is placed in place of one of the standard eyepieces. This allows you to use the microscope simultaneously for image capture and as an optical monocular microscope, though the focal distance you need may not be the same as what the image capturing unit requires. Keep in mind that the USB camera is very low resolution. You will always see much more detail by eye.

Yes. It has a small bottle of oil that is in a little resealable bag.(a miniature sandwich bag)Everything is in a molded Styrofoam box with a lid and though You cannot put the microscope back inside it after it has been assembled, it is great for all the supplies. If You ever had to travel with it,You could disassemble it and use the box again for that.

If you can't find the manual online, go to You Tube and do a search on your model microscope. Omax has some great videos on there that expain all you need to know about your scope, plus some tips on how to use it. I found them more helpful than the manual anyway. I'm sure you can also download the manual from the Omax site too, but definitly check out them videos. Hope this helps.

Probably at least 4x, which when combined with the eyepiece lense in most microscopes(10x) would be 40x, which would probably be plenty, u probably want to look for a microscope with a dissection light(shining down on the object) because otherwise you won't be able to see the scratches since the light on most microscopes shines through the bottom of the object as opposed to through the top..... A good microscope with a light shining down would be the "My First Lab Duo-Scope Microscope"....it's available through amazon for only $63.... Hope that helps

1.25 celestron accessory kit with 5 lenses from 6mm to 32mm. 2x barlow lense. moon and colord filters. think its $125, but necessary. reasonableand works great with my meade. and oh, they shipped me the wrong model , which wasn't the biggest deal, but would've been a major issue to exchange, so I kept the ng-60 which came in a box marked ng-70. make sure to check the mm by the eyepiece to confirm u get or got the right tube. nice scope. be gentle, and good luck.

I do not think that self evaluation of your blood is a viable use of this or any commercial microscope. High powered electron microscope would be an option but proper evaluation must be done by a properly trained lab technician.

The microscope has the ability to front and backlight. You can turn on the front and shut off the backlight. Is that the way to produce a dark field?

When using darkfield condenser to view live blood cells, the light intensity will reduce dramatically to provide contrast to the blood cells.
