Levenhuk 870T is a reliable biological trinocular microscope that may be used for the bright field observations. It is commonly used in various medical laboratories for clinical research in dermatology, biochemistry, cytology and other scientific studies. Due to the trinocular design of the head, this model may be turned into a digital microscope with an addition of an eyepiece digital camera.
The head of the microscope is inclined at 30 degrees and may be rotated 360 degrees around its axis. Four objective lenses on the revolving nosepiece, Köhler illumination method, adjustment of the aperture and field diaphragms make this microscope a perfect tool for serious observations.
The stage (140x155 mm, 5.5x6.1 in) moves along two axes. Focusing the view is achieved by rotating the coarse and fine focus wheels that raise or lower the stage itself, thus bringing the sample closer to or farther away from the objective lens. Both focus systems have smooth movements in 25 mm (1 in) increments for coarse and 0.002 mm (0.00008 in) for fine.
There is a variable brightness 6V 20W halogen lamp installed in the base of the microscope that acts as an illumination source.

The microscope’s maximum magnification is 2000x. You can obtain higher magnification with more powerful eyepieces, but it can affect image quality.
I want to buy a darkfield condenser for this microscope. I'm upset that this 870T doesn't come with a real darkfield condenser. Can you tell me the size of the condenser mount so I can add myself ? Klientu apkalpošana:
Dear Nick, thank you for your inquiry. The size of the condenser should be the same as the size of the condenser on your microscope. We've requested the data from our product manager as well. The result will be provided shortly.
how do I attach my c-mount camera to this ? (such as nikon 1 or m43 that has c-mount adapter attached) Klientu apkalpošana:
Dear Nick, thank you for your interest in Levenhuk products. You just need to insert the camera to the tube. The diameter is 23.2 mm. So, if you have another size, you will need to use the adapter that can be purchased in your local camera store. We also have a big choice of microscope cameras. Is there any additional information you might need?
Do I need to tint the bacteria while using a darkfield method? What is more efficient, tinting the bacteria or the darkfield method? If tinting is more efficient, which coloring should I use? Klientu apkalpošana:
When studying the bacteria, you need to tint them in any case. Food colorings will be perfect.
Sorry for the frequent questions. What do I do if the oil spot on the immersion lens has dried? Klientu apkalpošana:
Try to gently wipe the lens with the soft, dust-free cloth before trying to clean it with alcohol or other aggressive cleaning liquid. You can also use a piece of Styrofoam. First, remove the contaminated lens from the revolver. Rub the frontal lens with by tapping on it lightly with a piece of Styrofoam and turning it around. Dry foam material cleans the frontal lens from dirt (such as immersion oil) really well. You can easily check it by removing the eyepiece from the holder, turning it over and using it as a magnifying glass, keeping it at an acute angle over the front lens. You can simply see through this 10x magnifying glass if the front lens is clean or not. If not, repeat the procedure one more time. Then wipe the lens one more time, check it under the "magnifying glass" and put it back in place.
Can I attach the darkfield to the lenses with 40x and 100x magnification on this microscope? Klientu apkalpošana:
Yes, you can do it with the trinocular Levenhuk 870T microscope
Hello. Could you tell me please how I can attach the light filters to this model? There isn't any advice in the instruction Klientu apkalpošana:
Light filters are installed under the stage; there is a special niche for installing and fixing the light filters.
How can I observe objects in the darkfield without the condenser? Klientu apkalpošana:
You will need an Abbe condenser or a darkfield condenser in order to observe the samples in the darkfield.
Hello. I have just bought the microscope, it's awesome, but I can't figure out if the camera is included in the set? If yes, how do I use it? Klientu apkalpošana:
The Levenhuk 870T trinocular microscope is not equipped with a camera. A camera comes with a Levenhuk D870T microscope. You can also buy the camera separately here: https://www.levenhuk.com/catalogue/accessories/microscope-cameras/
Could you tell me how to switch to the dark field mode? Klientu apkalpošana:
Levenhuk 870T Biological Trinocular Microscope is not equipped with a dark-field condenser. An Abbe condenser is mounted. Dimming occurs due to the rotation of the condenser.
can I replace the halogen lamp with a LED one? Klientu apkalpošana:
Unfortunately, it is impossible.
There is a mirror in the kit but I didn't find any information on how to replace illumination bulb with the mirror... Klientu apkalpošana:
The process of replacing illumination bulb with the mirror goes as follows: 1) Turn the microscope over and and unscrew locking screws at the sides to open the base 2) Unscrew four screws locking the ring, remove the ring and the lens 3) Close the base with the cover and lock it with screws 4) Turn the microscope back to its normal position and install the mirror
What upgrades or accessories are available (LED illumination instead/polariser/phase contrast etc?? Are the objective D.I.N. standard or infinity or other? Klientu apkalpošana:
Dear Ben, Thank you for your question. Unfortunately we do not produce the mentioned accessories. The objective meets all the required standards. Is there any additional information you might need?
Can I observe opaque objects with this microscope? Klientu apkalpošana:
Levenhuk 870T Biological Trinocular Microscope does not have an upper illumination source, therefore, you can only observe transparent samples with it.

1. Trinocular has standard diameter. Adapters included in the kit are only needed for attaching a camera to the microscopes with another diameter. 2. Yes, a beam of light between binocular and the camera is controlled.
Is it possible to insert illumination source in the third eyepiece to get quality images in reflected light? Klientu apkalpošana:
Unfortunately, that cannot be done.
PLAN eyepieces is a good thing, but I was asking about objective lenses. The description on the site says: Objective lenses 4x, 10x, 40x, 100x PLAN, and at the same time it is stated in the user manual: DIN achromatic objective lenses. Klientu apkalpošana:
Included in the standard kit of this model are PLAN objective lenses.
Hi! Do you have a C-mount adapter for attaching a digital camera to this microscope? Klientu apkalpošana:
Unfortunately we don't have this adapter in our product range.
Thank you, no need to explain anymore, I figured it out myself. Klientu apkalpošana:
Thank you for your feedback.
Please explain how to use immersion objective correctly. I mean for me it seems that I do everything exactly as it's said in manual: I drip immersion oil on the cover glass and lower objective lens so it touches the oil… but I can't see anything, only white spot. Maybe I need to apply some oil on the condenser as well? Klientu apkalpošana:
The oil immersion objective (usually 100x or more) is designed for use with a drop of special oil, placed between it and the specimen. First you should focus on the area of specimen that you are going to observe using oil immersion objective. Then carefully place a drop of immersion oil on the cover slip over that area, and lower the oil immersion lens into place.
Hello. Where can I buy oil of these two types - A and B? And which of them magnifies more or what's the difference between them? Thank you. Can a vegetable oil be used? I want to purchase Levenhuk_c800 camera and Levenhuk 870T Biological Trinocular Microscope. I need your guidance. Klientu apkalpošana:
Unfortunately we don’t have immersion oil in our product range. Type A is a classic immersion oil Used as immersion liquid while working with apochromatic and achromatic objective lenses of microscopes of all types, except fluorescence microscopes, in visible spectrum. Type B is a professional immersion oil Used as immersion liquid while working with apochromatic and achromatic objective lenses of microscopes of all types, except fluorescence microscopes, in visible spectrum. Intended for microscopes with artificial illumination and image viewing system first of all. Compared to the classic immersion oil, immersion oil of B type has lower velocity and higher light transmittance. No, vegetable oil cannot be used. Do you want to process with the order?
Hello, is immersion oil included in the kit? Klientu apkalpošana:
Yes, immersion oil is included in the kit of the Levenhuk 870T Biological Trinocular Microscope.
Are all of the objectives of this microscope PLAN??? Klientu apkalpošana:
