Guy Coleman (2016-10-31 05:09): Positive
is the focusing coarse or fine? what is the material of the body? is it plastic? I think the lower lighting might heat the body if it's made of plastic... Levenhuk Customer Service:

Alberto Spears (2016-10-20 01:51): Positive
Hello! Is it possible to install a darkfield condenser on this model for viewing opaque samples? Levenhuk Customer Service:
To observe opaque samples, you won't need a darkfield condenser. What you need is upper lighting source. Unfortunately, we don't sell it separately, so we can only advise you to use a flashlight as an upper illuminator.

Mathew Reed (2016-10-16 06:18): Positive
If I manage to install an upper illuminator, what will be the maximum size of an opaque sample to fit under a 10x objective lens? If an object has uneven surface, what microscope (stereoscopic or this one) will perform best? Levenhuk Customer Service:
As the microscope is designed for viewing transparent samples, such tests were never conducted. For working with opaque samples we recommend using a stereoscopic model, please check this section of our catalog - https://www.levenhuk.com/catalogue/microscopes/type-stereo/

Kirk Crosby (2016-10-09 11:48): Positive
is it a digital microscope? Levenhuk Customer Service:

The image quality provided by Levenhuk 320 microscope at 640x and 1000x is very good. The Levenhuk 320 microscope is equipped with four objective lenses: 4x,10x, 40x, and 100x. Three of them (4x,10x, 40x) are used without immersion oil but they can't provide sufficient magnification to see bacteria. For that purpose you will need 100x objective lens that is only used with oil.

Lester Reed (2016-01-20 06:46): Positive

Please suggest a microscope at a reasonable price, so I can distinguish germs and DNA. Oh, and so the images would be high-quality. Levenhuk Customer Service:
Germs and DNA can be distinguished only by using electron microscopes which are very expensive ($20.000 and higher). Through the use of biological microscopes (e.g. Levenhuk 320) you can see the cell, cell structure, microorganisms, blood components, etc. Germs and bacteria are not visible through regular microscopes.

Tony Hill (2013-11-04 08:53): Negative
Good day. The website reads that the optics is made of glass and has a multi-layer coating. Two days ago I got three of these microscopes, so 'bout the coating, I'm not sure there is even one layer of coating. Out of curiosity I completely disassembled one eyepiece, and besides that the lenses were a bit dingy (but only in one eyepiece out of 6), they were without any coating, and flares on their surfaces were very bright, the same goes for the objectives btw. I would like this incorrect information to be deleted from the characteristics of the microscope (and don't try to tell me that there is a multi-layer coating, because when it's there you can see it immediately! Although in the pictures you can see the coating, but unfortunately not in reality). I've also got one more question about eyepieces: I read somewhere that the field of view of 10x is 18 mm, and of 16x is 15 mm, at the same time there were 10/15 mm and 16/11 mm in the kit. I mean how is that possible? Furthermore, if it's a biological microscope, then there has to be an option of installing a dark field condenser, but it's impossible with this microscope. Why do you say it's biological then? And why did you recommend it to me? I almost got fired by my dean. And how on earth are students supposed to study the blood with it? In general, there is a question whether it's possible to exchange or return it. Levenhuk Customer Service:
Optics is coated, not every coating is visible with the naked eye, and flares are also not the right criteria to determine it. Dark field condenser can't be installed on this model indeed, for this you need more advanced model. As for the return/exchange question please refer the following page: https://www.levenhuk.com/support/#returns or contact our Customer Service Department here https://www.levenhuk.com/feedback/

Why does a microscope need condenser? Where do I put an optical filter? Levenhuk Customer Service:
Condenser's optical system is meant for gathering and concentrating light entering the microscope. Condenser is located between an observed specimen (i. e. microscope's stage) and illumination system (i. e. light source). Learning and simple models more often than not have non-retrievable fixed condensers.

How to adjust a microscope correctly for observing at magnifications of 40x and 100x? And how to use an immersion oil the right way during observations under 100x magnification? Levenhuk Customer Service:
You can adjust a view with fine and coarse focusing screws. Immersion oil is a special type of oil that is used with 100x objective lenses (usually at a full magnification of 1000x). You need to place a drop of immersion oil on the cover glass and lower objective lens so it touches the drop. Immersion oil works as binding medium between cover glass and objective lens and thus increases image resolution. There are two types of immersion oil used in light microscopy - type A and type B, they differ in viscosity (type B is more viscous).
