We are constantly endeavouring to improve our instruments and
to adapt them to the requirements of modern research techniques
and testing methods. This involves modication to the mechanical
structure and optical design of our instruments.
Therefore, all descriptions and illustrations in this instruction
manual, including all specications are subject to change without
notice.

Microscope terminology
Abbe Condenser
A two-lens sub-stage condenser
located below the stage of a
microscope and functions to
collect light and direct it onto
the object being examined. Its
high numerical aperture makes
it particularly suited for use
with most medium- and high-
magnication objectives.
Aperture, Numerical (N.A.)
The numerical aperture is an
important factor determining the
e󰀩ciency of the condenser and
objective. It is represented by the
formula: (N.A. = ηsinα), where
η is the refractive index of a
medium (air, water, immersion oil
etc.) between the objective and
the specimen or condenser, and
α is half of the maximum angle
at which light enters or leaves
the lens from or to a focused
object point on the optical axis.
Cover Glass Thickness
Transmitted light objectives are
designed to image specimens
that are covered by a thin cover
glass (cover slip). The thickness
of this small glass piece is now
standardized at 0.17 mm for
most applications.
Diaphragm, Condenser
A diaphragm, which controls the
e󰀨ective size of the condenser
aperture. A synonym for the
condenser illuminating aperture
diaphragm.
Magnication
The number of times by which the
size of the image exceeds the original
object. Lateral magnication is usually
meant. It is the ratio of the distance
between two points in the image
to the distance between the two
corresponding points in the object.
Micrometer (um)
A metric unit of length measurement
= 1x10-6 meters or 0.000001 meters
Nanometer (nm)
A unit of length in the metric system
equal to 10-9 meters.
Phase–contrast (microscopy)
A form of microscopy, which converts
di󰀨erences in object thickness and
refractive index into di󰀨erences in
image amplitude and intensity.
Real Vieweld
The diameter in millimetres of the
object eld.
Eyepiece Field of View
Real Vieweld =
Objective Magnication
For example Stellar 1:
Eyepiece eld of view = 10mm
Objective magnication = 10X
Diameter of the object eld = 18/10
= 1.8mm

Diopter Adjustment
The adjustment of the eyepiece
of an instrument to provide
accommodation for the eyesight
di󰀨erences of individual
observers.
Depth of Focus
The axial depth of the space on
both sides of the image plane
within which the image is sharp.
The larger the N.A. of objective,
the shallower the depth of focus.
Field of View (F.O.V.)
That part of the image eld,
which is imaged on the
observer’s retina, and hence can
be viewed at any one time. The
eld of view number is now one
of the standard markings of the
eyepiece.
Filter
Filters are optical elements
that selectively transmit light.
It may absorb part of the
spectrum, or reduce overhaul
intensity or transmit only specic
wavelengths.
Immersion Oil
Any liquid occupying the
space between the object and
microscope objective. Such
a liquid is usually required by
objectives of 3-mm focal length
or less.
Resolving Power
A measure of an optical system's
ability to produce an image
which separates two points or
parallel lines on the object.
Resolution
The result of displaying ne details in
an image
Total Magnication
The total magnication of a microscope
is the individual magnifying power of
the objective multiplied by that of the
eyepiece.
Working Distance
This is the distance between the
objective front lens and the top of the
cover glass when the specimen is in
focus. In most instances, the working
distance of an objective decreases as
magnication increases.
X–axis Stage Travel
The axis that is usually horizontal in a
two-dimensional coordinate system.
In microscopy X-axis of the specimen
stages is considered that which runs
left to right.
Y–axis Stage Travel
The axis that is usually vertical in a
two-dimensional coordinate system.
In microscopy Y-axis of the specimen
stages is considered that which runs
front to back.

II. Setting up the instrument
Avoid placing the instrument in locations exposed to direct sunlight, dust,
vibration, high temperature and high humidity.
Operating environment
● Indoor use
● Altitude: Max 2000 meters
● Ambient temperature: 15°C to 35°C
● Maximum relative humidity: 75% for temperature up to 31°C decreasing
linearly to 50% relative humidity at 40°C
● Supply voltage uctuations: Not to exceed ±10% of the normal voltage.
● Pollution degree: 2 (in according with IEC60664)
● Installation / Overvoltage category: 2 (in according with IEC60664)
● Air pressure of 75kPa to 106 kPa
● Avoid frost, dew, percolating water, and rain
III. Assembling the microscope

● The 5V microscope input can works with a broad range of USB power
sources. However, always use the provided automatic voltage selection
power adapter or own adapter, portable power device that are rated for
the voltage used in your area, microscope input and that has been
approved to meet local safety standards.
● In order to prevent electric shock, always turn the power switch on the
power supply o󰀨 before connecting the power cord.
● Electrical specications:
AC adapter: 100-240V 50/60 Hz (Included)
Microscope Input: Type-C 5V/2A by AC adapter or portable power device
(not included)
2. Illumination
● LED illumination
LED Illumination Specication:

7
3.3V 1W, color temperature 5300K ~ 6000K
LED Power connection:
- Take out power adapter from the power adapter compartment on the
rear of microscope and power cord from the styrofoam packaging box.
- Connect the Type-C socket of the of the power cord to the inlet on the
rear of the microscope base. Plug in the other end of the cord to power
adapter and connect the adapter to an AC outlet.
● Reection mirror (Optional)
The mirror serves to be used for microscopic observation using natural
light in a location where power supply is not available.
- For this purpose, it is necessary to remove the transmitted light collector.
- Raise the stage up to the top position. Rotate the light collector in anti-
clock direction and remove it from microscope base. Rotate the reection
mirror into the microscope base and incline the mirror until the daylight is
reected homogeneously into the light path. Please use the concave face
of the mirror when natural light is not strong enough.
3. Mechanical stage
● Specimen holder has been attached in the stage by using the two
mounting holes.
●Open the specimen holding lever of the specimen holder, set the

8
specimen by sliding it on the stage from the front toward the rear. After
setting the specimen, return the specimen holding lever gently
●Remove specimen holder for fast hand scanning of slides
4. Objectives
● Objectives are installed in revolving nosepiece. If necessary to reinstall,
lower the stage completely, screw the objectives into the revolving
nosepiece so that clockwise rotation of the nosepiece brings the next
higher magnication objective into position.
5. Condenser
● The condenser is mounted in the stage and it is used in conjunction
with the iris diaphragm. The function of the condenser is to provide
full illumination to the specimen plane and to enhance the resolution and
contrast of the object being viewed.
6. Eyepiece tube
● Eyepiece tube is preinstalled in microscope arm. If necessary to reinstall,
loosen the eyepiece tube clamp screw, insert the round dovetail mount
on the eyepiece tube into the round dovetail mount on the microscope
arm, tighten the eyepiece tube clamp screw to secure the eyepiece tube
in place.
7. Eyepieces
● Use the same magnication eyepieces for both the eyes.
● Insert each eyepiece completely into the eyepiece sleeve.
● Twist the eyepiece (anti-clockwise or clockwise) with 20-30 degree and
put the eyepieces gently out when removing the eyepiece.
8. Filters
● The swing-in and swing-out lter holder is under Abbe condenser. Swing

9
it out and place 32mm diameter lter into it, taking care that dust, dirt and
ngerprints do not get on the lter and the eld lens.
●A di󰀨user is built into the condenser of the microscope.
IV. Usage of microscope components
1. Illumination brightness adjustment
● Turn the light intensity control wheel fully clockwise to the low brightness
position.
● Set the power switch on the rear of microscope to position “I” (ON)
● The brightness indicator of Swift Logo in the front of microscope base will
light up.
● When the light intensity control wheel is turned anti-clockwise to high
brightness position, the light intensity will increase.
●Automatic power o󰀨 function:
A safety and environmentally friendly feature in Stellar 1. If the brightness
is unchanged for 30 minutes, the microscope illumination will
automatically switch o󰀨. Turn the light intensity control wheel and the
illumination will automatically recover.
2. Interpupillary distance adjustment
● Before adjusting the interpupillary distance, bring a specimen into focus
using the 10x objective.
● Adjust the interpupillary distance so that both the right and left eld of
view become one.
