lighting the specimen from above. For viewing macro/translucent specimens, the Bottom lamp is,
generally, the most useful. You can use both Top and Bottom lights together if desired.

When using the Wolfe
Intermediate LED stereomicroscope, select either the 2X / 4X paired objectives
by rotating the black plastic, knurled objective knob located on both sides of the head. It is important to
ensure the objectives are fully engaged to avoid split or double images. The manufacturer has made
provision that the objectives engage in a positive, ball bearing click stop.
▪
Adjust the interpupillary distance between the eyepieces by either separating or integrating the large
prism barrels, below the eyepiece tubes and above the stereomicroscope head, until one image is
viewed through the eyepieces.
▪
While looking through the eyepieces and using the focus control knobs, located on both sides of the
arm of the scope, focus the specimen image by racking the head holder AWAY from the specimen until
details are clear. You will notice the great depth-of-field in the observed specimen. This results from
the stereomicroscope’s combination of low magnification and true stereo image. Refer to the “Features”
section for further explanation and detailed procedures for properly setting the eyepiece diopter(s) for
optimum performance.
If, at any or all magnifications, it is not possible to obtain a clear image verify: that the specimen is properly illuminated;
the interpupillary distance is properly set; and that the diopter(s) are correctly adjusted according to the procedure
outlined further in this manual.
FEATURES
WIDEFIELD 10X EYEPIECES
The 10X widefield eyepieces, furnished with this stereomicroscope, may be removed by pulling straight up
very gently
on the eyepiece.
ADJUSTABLE DIOPTER EYEPIECE TUBE
You will notice one or both of the eyepiece tubes of your Intermediate LED or Intermediate LED Zoom stereomicroscope
is capable of being lengthened or shortened by rotating the upper portion of the tube below the eyepiece. This
adjustment allows the user to compensate for individual differences between the right and left eye.
At the mid range of rotation of the diopter(s), you should observe a line engraved around the smaller portion of the
eyepiece tube. Initially, the base of the rotating upper portion should be even with this engraved reference. If your
stereomicroscope is equipped with only one diopter tube, focus a specimen, using the focus controls, while viewing
through the stationary (non diopter) tube, keeping the other eye covered or closed. Next, close the eye over the
stationary tube and focus while viewing through the diopter tube, and clearly focus the specimen by rotating the diopter
only. The stereomicroscope is now properly set to compensate for the difference between both eyes. If your
stereomicroscope is equipped with two diopter tubes, leave one tube set to the engraved reference mark to act as the
stationary tube per the previous procedure.
FOCUSING
The microscope has a 77mm working distance from the stage plate to the lens turret. The maximum specimen height is
36 mm. If you exceed the 36 mm specimen height, your item can not be focused. The focus control is made by rotating
either side or both of the focus knobs located on the support arm of the scope.
INCLINED TRINOCULAR HEAD
Your stereomicroscope is equipped with an angled head. The 45
angle will promote user comfort when viewing
specimens for extended periods. The head should be mounted onto the base and held tight with the head locking
thumb screw. The camera port is supplied with a C mount camera adapter so that the Motic Tablet can be mounted.
REFLECTED AND TRANSMITTED ILUMINATION
The built-in illuminators provid
e both “incident” (reflected), and “transmitted” light independently or simultaneously.
The “ Main
” power switch must be in the up position ( I ) for the illuminators to work. The main power switch in the ( 0 )
position turns all power and lights off. The scope has a choice of Directional Light with the Top B light ( switch in the
down position) or the Top A light( switch in the up position) is a Flat Light from an array of six LED bulbs on the
objective turret. With the switch in the center position the top light is off. To control the bottom light the ( I ) for on and
the ( 0 ) for off.
All three choices can be adjusted with the dimmer dial. The dimmer is set in light increments from “ 0 “
