Using the lamp in a low voltage condition, will prolong the service life.

Adjusting the tension adjustment collar (Fig. 18)

The tension of the coarse focus knob (2) has been pre-adjusted at the factory.

How to adjust the tight tension:

Turning the tension adjustment collar (1) in the direction shown by the arrow on the figure, will increase the tension of the coarse focus knob (2). Turning it in the opposite will decrease the tension.
If the nosepiece drops automatically, or the specimen defocused despite focusing with the fine focus knob (3), it means the coarse focus knob is too loose. Turn it in the direction of the arrow shown in figure 18.

LAB-BASICS-MIC0116-Inverse-TC100-Inverted-LED-Microscope-FIG- (19)

Setting the specimen (Fig. 19 & 20)

Set the specimen in the centre of the stage. To obtain the best observation results, select containers such as culture dishes and culture bottles with a bottom thickness of 1.2mm. The same thickness is also required for the object slide when placing the specimen.

Using the Ø35mm culture dish
You can lay a Ø35mm culture dish on the stage directly by using the standard centre board (1) of the stage.

Using the mechanical ruler

  1. When using the 96bit or 24bit micro-titration board, please fasten it tightly by the stage clips (2).
  2. When fastening other model boards, please use the following supplied brackets with mechanical ruler:
    • Terasaki bracket (3) for Terrasaki board
    • Culture dish bracket (4) for Ø35mm culture dish
    • Object slide bracket (5) for object slide and Ø54mm culture dish
  3. Turning the transverse knob (6) and lengthways knob (7), move the specimen to the required position (movement range, width x length: 120 × 78mm).

LAB-BASICS-MIC0116-Inverse-TC100-Inverted-LED-Microscope-FIG- (20)

Moving the specimen
Turn the knob of the mechanical ruler or manually move the specimen to the position required.
Be careful when you replace the objectives, especially after a short work distance observation. Do not let the objective to touch the stage inserted plate or the culture dish bracket.

The viewing tube

Adjusting the diopter (Fig. 21)
Look into the right eyepiece by your right eye, then revolve the coarse focus knob to focus on the specimen. Then use your left eye to look into the left eyepiece. If the image is not sharp, use the diopter adjustment ring (1) to adjust.

LAB-BASICS-MIC0116-Inverse-TC100-Inverted-LED-Microscope-FIG- (21)

There are ±5 diopter in the adjustment ring (1). The number which the reticle on the eyepiece holder pointed is your eye’s diopter graduation.

Adjusting the interpupillar distance (Fig. 22)
When observing with both eyes, hold the left and right prism holder, turn around the axis, adjusting the interpupillar distance until the left and right fields of view coincide completely.

The reticle on the interpupillar distance indicator (3), pointed by the spot “.” (2) on the eyepiece holder, shows the scale of the interpupillar distance (fig. 21).

LAB-BASICS-MIC0116-Inverse-TC100-Inverted-LED-Microscope-FIG- (22)

The range of the interpupillar distance is 48–75mm.

Switching the light path (Fig.23)

  • Pulling out the light path selector lever (1) using your thumb, select the light path required.
  • When in the binocular observation, push in the lever until you hear a “click” . While in video or photography, pull out the lever until it reached the “clicked” position.

Colour filterMeaning
IF550Single contrast colour filter (green) (used for the phase contrast microscopy)
LBDColour temperature transit colour filter (blue) (used for bright field observation and microphotography)

Using the aperture diaphragm (Fig. 25)

In bright field observation, the aperture diaphragm controls the numerical aperture of the illumination system. To achieve higher image resolution, contrast, and increased depth of field, the numerical apertures of both the objective and the illumination system must match.

To identify the aperture diaphragm, you can remove the eyepiece if necessary (or insert in the centre telescope), and look into the viewing tube. You should see a field of view similar to the figure shown. The proportion can be adjusted by dialling the aperture adjustment lever as needed. ((1) represents the image of the aperture diaphragm, and (2) indicates the edge of the objective).

Generally, when observing the chromatic specimen, you need to set the size of the condenser aperture diaphragm at 70%–80% of the numerical aperture which marked in the objective. However, when observing non-coloured bacterial specimens, turn the aperture diaphragm lever clockwise

Phase contrast viewing

The name of the components

Phase contrast objective (Fig. 26)

  • The optional magnification of the phase contrast is :10X, 20X
  • If you want to know how to mount the phase contrast objective, please see 2-2-4. You should to mount it on the turret.

LAB-BASICS-MIC0116-Inverse-TC100-Inverted-LED-Microscope-FIG- (26)

Phase contrast slider (Fig. 27)

Phase centering adjustable slider:

  • The light ring was centred beforehand, so it does not need to be adjusted during use. If the ring is not centred, you can adjust it using the centring bolt.
  • The 10X/20X light ring (1) is used with the 10X,20X phase contrast objective, while the opening (2) is used for bright field

The installation and use

Installing the phase contrast slider (Fig. 28)

  1. Insert the slider (1) with the surface that has the characters facing up, into the illumination system from right to left, as shown in the figure.
  2. Each light ring or opening has its own designated position, so move them until you hear a “click” to ensure the ring or opening is centred in the light path.
  3. For phase contrast observation, keep the aperture diaphragm adjustment lever (2) in the “O” (off) position (wide open).

LAB-BASICS-MIC0116-Inverse-TC100-Inverted-LED-Microscope-FIG- (27)

The centering ring (Fig. 29 & 30)

Usually, centring is not necessary. If required, please follow these steps:

  1. Place the specimen on the stage and focus it.
  2. Remove the eyepiece and replace it with the CT (centring telescope), inserting it into the viewing tube without adjusting the diopter.
  3. Ensure the matched phase contrast objective and light ring (in the phase contrast slider) are centred in the light path.
  4. Use the CT to view the light ring’s image (1) and the phase contrast ring’s image (2). If the light ring’s image is not sharp, adjust the CT’s eyepiece until the image of the light ring (2) is clear.
  5. Using a screwdriver, adjust the bolts of the two centring holes (3) in the phase contrast slider until the centre of the light ring coincides with the centre of the phase contrast ring.
  6. The 10X and 20X phase contrast objectives use the same light ring on the phase contrast slider. Check the coincidence of the light ring centre and the phase contrast centre when changing the objective. If there is any misalignment, re-centre them.
    • If the light ring is not correctly centred, you will not achieve the best viewing effect with the microscope.
    • After removing or replacing a thick specimen, the light ring and the phase contrast ring may become misaligned, resulting in reduced image contrast. If this occurs, please repeat the steps outlined above.
    • If the container or cover slip used to place the specimen is not flat, you may need to repeat the centring steps to achieve optimal contrast. Centre the light ring using the phase contrast objective, starting with low magnification and progressing to higher magnification.
