IRIS DIAPHRAGM – The iris diaphragm is a round device that is
mounted below the condenser. It has multiple leaves similar to a
camera shutter. By moving the control lever from side-to-side, the
opening in the diaphragm increases or decreases, allowing the user to
control the contrast of the specimen. If the image is “washed out” the
iris diaphragm is opened too wide. If the image is too dark the iris is
not open wide enough.
MECHANICAL STAGE - an alternative to stage clips is a mechanical
stage. A mechanical stage holds the slide in place and allows the
user to move the slide along the x and / or y axis through
manipulation of the two mechanical stage control knobs.
NOSEPIECE – the
revolving turret that holds the objective lenses.
Changes in magnification are accomplished by rotating different
powered objective lenses into the optical path. The nosepiece must
“click” into place for the objectives to be in proper alignment.
OBJECTIVES – the optical systems which magnify the primary image of
the instrument. Magnifications are usually 4X, 10X, 40X and 100X.
STAGE – the table of the microscope where the slide is placed for
viewing. This component moves upward and downward when the
focusing knobs are turned.
STAGE CLIPS - a pair of flexible metal clips attached by spring
screws that hold the slide in position on the stage.
OTHER IMPORTANT TERMINOLOGY
“COATED” LENS – in attempting to transmit light through glass, much
of the light is lost through reflection. Coating a lens increases the
light transmission by reducing or eliminating reflection, thus allowing
more light to pass through.
COMPOUND MICROSCOPE – a microscope having a primary magnifier
(the objective) and a second (the eyepiece) to both conduct light,
amplify magnification and convert the image into a field of view easily
seen by the human eye.
COVER GLASS - thin glass cut in circles, rectangles or squares, for
covering the specimen, usually a thickness of 0.15 to 0.I7mm. The
9
Limited Lifetime Warranty will be null and void if the mechanical or
optical components are disassembled by a non-Swift dealer.
A. PROBLEM
–
No Image
CORRECTION -
1. Is the objective fully rotated into position (until it clicks into
place)?
2. I
s the specimen in the focal path (centered in the opening in the
stage above the condenser)?
3. Is the iris diaphragm completely closed?
B. PROBLEM
–
No Illumination
CORRECTION -
1. Is the power plug connected to an active A.C. outlet?
2. Is the illuminator intensity control turned all the way down?
3. Replace the LED
4. Is the power switch working properly?
C. PROBLEM – Image appears “washed out” or weak.
CORRECTION
-
1. Slowly close the iris diaphragm.
2. Objective lens is dirty. See “Care and Cleaning” section.
3. Eyepiece is dirty. See “Care and Cleaning” section.
D. PROBLEM
– Dust or hairs seem to be moving in the image.
CORRECTION
–
The diaphragm is not open wide enough. Open the
iris diaphragm to increase the size of the opening allowing for
additional illumination.
E. PROBLEM – Focusing knobs turn with difficulty.
CORRECTION – The microscope should be disassembled, cleaned
and
re-lubricated by a qualified, authorized technician.
