T720 Series Microscope 1.2 Features This brand new professional trinocular compound microscope comes equipped with an infinity plan optical system and offers advanced features as well as research grade performance. Its crystal clear optical and precise mechanical systems promise high quality performances for advanced applications.
T720 Series Microscope 2. Operation 2.1 Unpacking 2.1.1 Unpack the Box 1. Very carefully slide the Styrofoam container out of the cardboard carton. 2. Lay the Styrofoam container on its side. Make sure the side labeled up is up. 3. Remove the tape.
T720 Series Microscope 2.2 Assembly 2.2.1 Carefully Remove Microscope from Box Remove the microscope body from the box and remove the plastic protective covering. The body of the microscope is composed of the base, the stage, the arm, and the nosepiece.

T720 Series Microscope 2.2.4 Install the Trinocular Port and C-Mount Unscrew and remove the photo port cap from the top side of the microscope head. Screw in the Trinocular port. If your camera has a c-mount, insert the c-mount adapter onto the Trinocular port.

T720 Series Microscope 2.2.6 Insert Objective Lenses Unpack the objective lenses. Screw the objectives into the microscope nosepiece. Start with the lowest magnification, and in order of magnification, insert each lens, without touching the glass. 2.2.7 Plug it in, turn it on, and adjust the dimmer if more light is needed.
T720 Series Microscope 2.3 Adjusting the View 2.3.1 Choose forward or reverse viewing The microscope head rotates to allow for forward or reverse viewing. There is no difference as far as the optics; it depends on what’s comfortable. In forward position you are looking over the stage, in reverse position you are looking at the stage.
T720 Series Microscope 2.4 Specimen Set Up 2.4.1 Prepare the Specimen Place the specimen to be studied on a glass slide (or use a prepared slide, purchase separately). 2.4.2 Secure the Slide Place the slide on the stage, holding it snugly in place with the metal slide holders (clips) of the mechanical stage.
T720 Series Microscope 2.5 Focusing 2.5.1 Choose an Objective Lens Turn the nosepiece to choose an objective. It is easiest to use the lowest magnification first (4X objective) to locate and focus on the specimen. As you move up in magnification you will need to refocus the image a little each time.
T720 Series Microscope 2.6 Using the Trinocular Port The AmScope T720 model is uniquely designed so that you can view the image through the eyepieces and the Trinocular port simultaneously, as well as fine tune the focus of the camera with a C-mount focus adjustment.
T720 Series Microscope 2.8 Setting the Stage’s Stop-Limit 1. Unlock the stop-limit on the stage. 2. Adjust the stage to the desired maximum height. 3. Lock the stop-limit. This allows you to limit the movement of the stage from the bottom of the range up to the point it is set at.
T720 Series Microscope 2.11 Adjusting the Iris By changing the aperture (hole size) of the iris/diaphragm of the condenser, you can adjust the background brightness. Adjust the aperture of the iris diaphragm using the numbered iris adjustment ring located directly under the stage.
T720 Series Microscope 2.14 Using Oil Immersion When using the 100X objective, a drop of immersion oil should be placed between the cover slip and the objective to minimize distortion caused by air. 1. Place the slide on the stage and center the specimen.
Page 18
T720 Series Microscope 7. Re-engage the stage stop limit. 8. When the specimen is in focus, adjust the iris to open just larger than the condenser’s diameter. 9. After using the oil immersion lens, you will need to clean the lens and specimen before the oil dries.
T720 Series Microscope 2.15 Using Darkfield Condenser Lenses (Optional Accessories) Darkfield Illumination is a lighting method for increasing contrast. A darkfield condenser lens produces bright images against a dark background for low contrast biological specimens. The dry darkfield condenser is for low power magnifications, such as with the 4X, 10X or 40X objective lenses, with numeric apertures of .65 or less.
T720 Series Microscope 2.16 Using a Dry Darkfield Condenser Lens (Optional Accessory) 2.16.1 Using the Dry Darkfield Condenser 1. The first step is centering the condenser. Move the 10X objective lens into the light path. 2. Remove an eyepiece and look through the empty eye tube, to see the condenser’s image directly.
T720 Series Microscope 2.17 Using Oil Darkfield Condenser Lens (Optional Accessory) The condenser works with 100X oil objective and low power objectives (4X, 10X, etc) as well. Immersion oil is needed on top of the condenser lens for darkfield observation. Immersion oil is needed between the 100X oil objective and slide.
Page 22
T720 Series Microscope 2.17.2 Using Oil Immersion 1. Before you install the oil darkfield condenser lens, apply a drop of immersion oil on the top lens of condenser. If you’ve already installed it, remove the condenser to apply the drop of oil to the lens, and re-install it.
Page 23
T720 Series Microscope 2.17.3 Cleaning the Oil Darkfield Condenser 1. When using oil immersion, once you have finished using the oil darkfield lens, you will need to clean the lens and specimen of the oil before it dries. 2. You can wipe the lens with a soft nonabrasive cloth to remove the oil. If you want to use a cleaner, you can use cigarette lighter fluid to safely remove the oil, as it will break it down.
T720 Series Microscope 2.18 Microscope Maintenance 2.18.1 Handle with Care As the microscope and all accessories are precision instruments, always handle them with care, avoiding impact or abrupt movement during transportation. Do not shake the package. 2.18.2 No Sun/Heat Do not place the microscope and accessories in direct sunlight or in high heat.
T720 Series Microscope 2.18.8 Do not take apart the microscope. Do not assemble or disassemble the microscope’s electrical components yourself. 2.19 Darkfield Condenser Kit Maintenance 2.19.1 Secure Setting Ensure that the microscope is located on a smooth, level and firm surface.

T720 Series Microscope Condenser Lens Adjustment Knob The Condenser Lens Adjustment Knob changes the distance between the light condenser and the base lens. This allows you to control the concentration of the light hitting your slide.

T720 Series Microscope Diopters Small rings on the eyetubes, used to focus ocular lenses (eyepieces). Eye Guards Eye Guards fit over the eyepieces, they are for comfort and to protect the glass in the eyepiece. Eyepieces Eyepieces are also called ocular lenses. Eyepieces come in many magnifications and you replace them by swapping them out of the eyetubes.
Page 40
T720 Series Microscope Field of View and Working Distance Field of view is how much of the specimen you can see through the eyepiece. The linear field of view of the eyepiece is divided by the magnification of the objective.
Page 41
T720 Series Microscope Head Types Monocular Monocular microscope heads have one eyepiece. Binocular Binocular microscope heads have two eyepieces. Trinocular Trinocular microscope heads have two eyepieces and a photo port for a camera. This allows you to look at a specimen with a camera without removing an eyepiece.
Page 42
Interpupillary Distance Interpupillary Distance is the distance between your eyes. AmScope uses 2 types of systems to change interpupillary distance. Siedentopf heads adjust the interpupillary distance by rotating the eyetubes around a central axis.
Page 43
When changing light bulbs cover skin with cloth or paper to handle the bulb. This will protect both you and the bulb. 3. Hot bulbs will not damage the microscope. AmScope’s microscopes are designed specifically to handle the heat output of the model’s bulb.

T720 Series Microscope Limit Stop Knob The limit stop is designed to prevent impact between objective and slide. You may loosen the limit-stop knob in order to give yourself the full range of motion for fine tuning the focus when using the 40X and 100X objective lenses.
