Parts overview

*not for model TFM-201

Scope of delivery

Microscope (A); 10x WF Eyepiece (B); 4 Objectives (pre-assembled) (C); Condenser (pre-assembled)(D); Power adapter with plug and cable (E)

Choice of location

Choose a suitable location before installation and commissioning.Place the device on a stable, level and vibration-free surface.

 Installing the USB power adapter

Illustration 3: USB power adapter with exchangeable attachment

1. Place suitable adapter attachment with its notches on the pins of the USB power adapter.
2. Turn the adapter attachment in the LOCK direction until it is locked.
3. Put the USB plug of the power cable into the USB port of the power adapter.
4. To remove the adapter attachment, push the PUSH button and turn the attachment in the OPEN direction.

NOTICEUsing the USB power cable with a computerAlternatively, the device can be powered by a computer via the included USB power cable: Put the USB plug into a free USB port of the computer.

Setting up power supply

Illustration 4: DC connection socket for coaxial/barrel connector

1. Put the DC connector of the power cable into the DC connection socket of the device.
2. Put the mains plug of the power cable into the power outlet.

Turning on/off the device

1. Move On/Off switch to position ‘I’ to turn on the device.
2. Move On/Off switch to ‘O’ position to turn off the device.

Adjusting the lighting

Illustration 5: Lighting unit

NOTICEDo not operate the device on the highest brightness over a longer time!This will reduce the lifetime of the LED.To control the brightness proceed as follows:

1. Turn on the device.
2. Turn/Move the dimmer control to adjust the brightness of the light source.

NOTICEIlluminating the object optimallyAdjust the brightness of the light source so that the illumination works at its optimum. Depending on light influences from outside and the object being observed, the illumination needs regular adjustments.

Adjusting the eye distance

Illustration 6: Distance between the eyepieces and diopter adjustment

1. With the eyes look through both eyepieces.
2. Change the distance between the eyepieces by pushing them together or pulling them apart until a circular image of the observed object is visible.

Diopter adjustment

1. Turn the diopter adjustment ring to position ‘0’.
2. With the left eye, look through the left eyepiece and turn the focusing wheel until a sharp image of the observed object is visible.
3. With the right eye, look through the right eyepiece and turn the diopter adjustment ring until a sharp image of the observed object is visible too.

The diopter adjustment can also be done in the opposite way on the left eyepiece.

Using the iris diaphragm

NOTICEThe iris diaphragm is used to increase the depth of focus.With an open aperture more light is getting through but the depth of focus is less. With a partially closed aperture, the depth of focus is higher but it is necessary to increase the brightness of the illumination then.It is recommended not to close the iris diaphragm too much when working with higher magnifications. Otherwise, the image resolution will decrease.

Using the Köhler illumination

1. Focus on the object with the 10x objective.
2. Close the condenser and the light field aperture. For microscopes with additional lenses, fold it out.
3. Move the condenser up and down until the edge of the light field aperture is in focus.
4. If necessary, use the adjustment screws to move the condenser until the light field aperture is centered in the field of view.
5. Open the light field aperture as far as it is not visible in the field of view anymore.

Oil immersion

1. Focus on the object with the 40x objective.
2. Turn the 40x objective sideways.
3. Drop a drop of immersion oil onto the cover glass of the preparation.
4. Retract the 100x objective so that it is immersed in the oil.
5. Refocus the image.
6. Clean the 100x objective after each use.

Using the trinocular extension

The trinocular extension of the microscope was specially designed for C-mount threads. For the camera mounting proceed as follows:

1. Remove the dust protection cap from the trinocular head.
2. Attach the camera* with its C-mount thread to the photo adapter thread and turn it on.
3. Loosen the clamping screw of the trinocular extension to move the photo adapter with the camera* within the extension tube. In this way, the image sharpness and the position of the camera can be adjusted. Most camera models can be adjusted parfocal to the eyepieces when doing so.
4. Re-tighten the screw to fix the camera in the desired position.

*not included

Cleaning and maintenance

• Protect the device from dust and moisture!
• Avoid fingerprints and similar contamination of the optical surfaces.
• The residual moisture must be completely degraded before use.
• Disconnect the power supply by pulling the mains plug when the appliance is not in use, in case of a longer interruption of operation and before any maintenance and cleaning work.
• Only clean the device externally using a dry cloth. Do not use a cleaning solution to prevent damage to the electronic parts.
• Do not use organic solvents (e.g. alcohol, ether, acetone, xylol or other dilutions) to clean lacquered parts or plastic parts!
• Disassemble optical elements (e.g. objective, eyepiece, etc) before cleaning.
• Blow away loose dust from the lens surfaces first.
• Use high-quality lens cleaning towels or soft cloth and moisten it with a little bit of pure alcohol (available in a drug store). Wipe the lens surface with it.
• Pull a dust protection cover* over the microscope and store it in a closed container at a dry and mold-free place. Store the microscope and the accessories in the relevant containers when they are not used for a longer time. It is recommended to store also objectives and eyepieces in closed containers with desiccant.

(*depending on the model a dust protection cover and box can be part of the content)

NOTICERemember:A well-maintained microscope will keep its optical quality for years and thus maintain its value.
