RED 30 SERIES
4.1 Binocular stereo microscope head
For the RED30S and RED39Z, the binocular tubes and the objective turret are integrated to a single part called
“stereo microscope head”.
4.1.1 Stereo microscope head
• For RED30S model , the operator can select the desired magnification by rotating the objective turret.
• For RED30S either of two levels of magnification can be selected, The RED39Z model incorporates a zoom objec-
tive which allows the user to zoom continuously from the lowest magnification up to the highest magnification. If the
microscope has been adjusted according to the requirements in Section 3.2 of the Operation Instructions, the image
will be parfocal and require no further adjustment when the magnification is changed.
• For RED30S model, the stereo microscope head is integrated into the stand and cannot be removed.
For RED39Z model, the stereo microscope head can be removed from the stand. When installed it should be se-
cured by tightening the right lock screw.
4.1.2 Binocular tubes
• The interpupillary distance can be adjusted by moving the left and right binocular tubes. Please refer to the Section
3.2.1 of the Operation Instructions for the correct method of adjustment.
• The eyepiece is fixed in the body tube with a small set screw that prevents the eyepiece from falling out.
• The diopter ring is located on the left body tube. Please refer to the Section 3.2.2 of the Operation Instructions
for the correct method of adjustment.
4.2 Stand
• The focus knobs on both sides of the stand are used to bring the image in focus. Focusing is done with a pinion-and-
rack gearing mechanism. The tension of the focus knobs can be adjusted by using the tension adjustment ring inside
the right focus knob. The required hook wrench is supplied with the stereo microscope.
• Generally, the black/white contrast stage plate is used with the incident illumination. Use the frosted glass stage
plate with the transmitted illumination.
• There are controls on either side of the base which turn the incident and transmitted illumination on and off and adjust
the brightness. Both illuminators can be adjusted independently, so any combination of illumination can be selected.
• The main power switch is located at the back of the base.
4.3 Eyepieces
• Various eyepieces with different magnifications are available, including 5X, 10X, 15X, 20X and 30X. The stereo
microscope is generally supplied with a pair of 10X eyepieces.
• To replace the eyepieces, first loosen the lock screws and remove the existing eyepieces with the provided hex
wrench, and then install a new pair of eyepieces and tighten the lock screws. The lock screws should be adjusted
so the eyepieces will turn in the eyetubes, but will not pull out.
