Page 3: Safety Notes
(preventing any damage to the DX41). When the DX41 is in use, the lamp housing and nearby parts will be very hot. Please ensure there is enough room surrounding them to enable them to cool down. -
Page 4: Maintenance
Maintenance All the lenses have been thoroughly checked and adjusted - do not try and disassemble them yourself! The nosepiece and coarse/fine focus unit have a compact and precise frame. Please don’t disassemble them. Keep the instrument clean by wiping dust regularly and avoid contaminating the optical elements. Contamination on the prism, like finger prints and smears, can be gently wiped with a piece of soft cloth or gauze which has been immersed in pure alcohol or xylene*. -

Assembly Assembly Diagram The following diagram shows the assembly sequence of the components. The number in the figure shows the assembly steps. Before assembling, make sure every component is clean and be careful not to scratch any of the parts or glass surfaces. -
Page 7: Installing The Mechanical Stage Support Device
Installing the Mechanical Stage Support Device Before installing the device, make sure you adjust the coarse focus knob. Turn the guide board (see figure 1) down to the lowest position so you can install the mechanical stage support device easily. Hold onto the mechanical stage support device (figure 2), place it on the top of the guide board (figure 1), let the device... -
Page 8: Installing The Trinocular Viewing Unit
Installing the Trinocular Viewing Unit Insert the trinocular viewing unit (figure 4) into the microscope head (figure 5), turn it to an appropriate position, then use the hexagon wrench to screw down the bolt (See figure 5). Installing and Replacing the Lamp (figure 6) Please use the specified halogen Lamp 6V/30 or 12V/50 Carefully hold the bulb with gauze or other... - Page 9 www.visionbiomed.com Routine Laboratory Microscope...

Page 10: Installing The Objectives
Installing the Objective Adjust the coarse focus knob until the support device of the mechanical stage reaches its lowest limit position. Reset the lowest magnification objective onto the nosepiece from the left or the right side (figure 9), then push the nosepiece clockwise. -
Page 11: Installing The Eyepieces
Installing the Eyepiece Insert the eyepiece (figure 11) into the eyepiece tube, until they are against each other. This is shown in the figure 14. Installing the Video Port (optional) Insert the video port (figure 12) into the trinocular unit (figure 13), then screw down the bolt to fix it in place - see figure 14. -

Page 14: Operation
Adjusting the Tension Adjustment Collar (figure 17) The tension adjustment collar has been set during the manufacture of the DX41, if you find it’s loosening (the mechanical stage might drop because of its heavy weight), turn the tension adjustment collar until it is tight and securely fastened. -
Page 15: Adjusting The Interpupillary Distance
Adjusting the Interpupillary Distance (Figure 19) The interpupillary distance range: 48mm 75mm. When observing with both eyes, hold onto the left and right prism holders and turn the axis around. Adjust the interpupillary distance until the left and right fields of view coincide. Adjusting the Dioptre (Figure 20) The right ocular tube is fixed. -
Page 16: Adjusting The Swing-Out Condenser
Focusing (figure 21, figure 22) When the video set is not in use. Push in the light path selector lever (figure 25) then observe with both eyes. Use the x10 objective to focus and avoid touching the specimen with the objective. Raise the mechanical stage slowly. The operator can turn the coarse focus knob to get the specimen broadly in focus and search in the x10 ocular simultaneously, and then use the fine knob to focus... -
Page 17: Using The Swing-Out Condenser
Using the Swing-out Condenser When using a low magnification objective, swing the condenser out and let it swing away from the light path. While using the high magnification objective, turn it into the light path. Adjusting the Aperture Diaphragm The aperture diaphragm is designed for the adjustment of the numerical aperture, not for the brightness. Generally, reducing the diaphragm (opening to 70- 80% of the N.A.) value of the respective objective will provide an image of acceptable quality. -
Page 18: Adjusting The Field Diaphragm
Adjusting the Field Diaphragm (Figure 24) The control for the field diaphragm is a ring used for adjusting the area of field diaphragm. When using, turn the ring to reduce the field diaphragm, look into the field and if the diaphragm image is faint, perform the follow steps: turn the condenser focus knob shift the condenser holder to the position where the observed image of the field of view is sharp... -
