1.3. Cautions
⚫Always protect this instrument with Dust Cover after using.
⚫Do not vibrate or drop this instrument; it can cause damage.
⚫Use soft cloth or cotton swaps with alcohol when clean the 4 pinhole.
1.4. Software OS version
Software OS version will be shown on the screen if you turn on the power switch.
1.5. Optical System
Optical system resolves the features of the lens such as diopter and prism. It is
composed of emitting light part, transmit part and receiving light part: transmit
part composed of collimator lens, 81pinhole and receiving light part composed of
2-dimentional CMOS sensor. The followings are the components of each part:
Emitting Light Part
⚫Optic LED : 545nm
⚫Ball Lens : condenses the light radiated from Optic LED.
⚫Rubber Ring : fixes ball lens.
⚫Filter Paper : prevents the dispersion of light.
⚫LED Cylinder : combines above components and blocks exterior light.
Transmit Part
⚫Collimator Lens: makes parallel light.
⚫Pinhole : disperses parallel light into several signals. Prevent the other
light except the light source
⚫MLA : micro lens array. Focus the every spot.
Receiving Light Part
⚫2-dimentional CMOS sensor : converts signals into digital value.
Emitting light part and receiving light part also built optical system for UV
measurement. One is composed of UV lamp and the other receives UV light. The
wavelength of the UV light is 395nm.

Measurement Principle
Basic Principle
When there is no lens (0D state), parallel light that has transmitted the collimator
lens passes the pinhole and makes image on CMOS. In case of convex lens (lens
with plus diopter), parallel light that has transmitted the collimator lens converges
through the measuring lens, passes the pinhole and then makes image on CMOS.
On the other hand, in case of concave lens (lens with minus diopter), parallel light
that has transmitted the collimator lens diverges through the measuring lens and
then passes the pinholes and at last makes image on CMOS.

2. Checking and Setup Method
2.1. Setup Order
When you turn on the power switch, you should hear the beep sound and see the
ROM information. At this point, press the two buttons together in the third button
and sixth button. Then, after the beep sound, your lensmeter, CLM-9000 will start
in setup and check mode. The booting steps for‘SETUP’mode are as follows:
A. Turn on the power switch. Then you can hear the beep sound.
B. Press the two buttons together in the third button and sixth button.
C. Check that ‘SETUP’mark flickers in the left-upper area of the
centric circle.
Setting and Calibration only can be processed in SETUP mode; lens, 0D prism,
cylinder, UV and right/left switching position of PD. To all setting, you should
convert the display step (STEP) into 0.01. In case of prism, convert the prism
display into X,Y format. Display step (STEP) and prism display format can be
changed in ‘User Setup’screen. To enter the‘User Setup’screen, press the ‘USER
SETUP’(button 4) in the SETUP main screen.

2.2. How to 0D Setup
When there is lens mark or diopter/cylinder values without lens, Perform 0D setup
A. Before 0D setup, clean LM lens and 81pin holes
B. Press the ‘LENS SETUP’(button 1)
C. Press the ‘MEASU’button.
D. It will have 6th DIP : +0.00 message. If not using‘-INDEX’, ’+INDEX’buttons
select 6th.
E. Also if the message doesn’t have +0.00 value, using ‘D-0.01’, ‘D+0.01’
buttons adjust it to +0.00 value
F. Press ‘SAVE’
G. Alignment data will be shown. Press ‘EXIT’
But
tons for Selecting Diopter Buttons for Calibrate Diopter SAVE button QUIT button
If you want to return to the previous one without saving in the SAVE screen, press
the rightmost ‘PREV’button.

2.3. How to Set 12 standard lenses
If the measured value is not accurate, you should set the diopter variables again
by using the standard lens-set: for all the 12 lenses in the standard lens set.
Always keep the standard lens clean and out of dust or stain.
A. Set the diopter display step into 0.01.
B. Place the standard lens and move it so that ‘Marking OK’will appear.
C. I and U values (in red circle) should be within 0.03
D. Press the ‘LENS SETUP’button.
E. Press the ‘MEASU’button.
F. Determine the lens to measure by using two ‘-INDEX’, ’+INDEX’buttons in
the left side.
G. ‘D-0.01’button and ‘D+0.01’button by the given value in the standard
model-eye specification.
H. To save, press the ‘SAVE’button.
I. Check whether the diopter that has been set up is shown in the DATA
INFORMATION. Press ‘EXIT’
J. Repeat the procedures from B to H for 12 standard lenses.

2.4. How to Set Prism
If the measured value is not accurate, you should set the 2, 5, 10lens again by
using the standard lens-set.
A. First, convert prism display format into X, Y.
B. Then, press the ‘0D PRISM’button.
C. After selecting the 2lens from the standard lens set, place it on the lens cap.
D. Using‘D-0.01’and ‘D+0.01’buttons, make lens value to the real value in the
standard model-eye specification.
E. Rotate the lens to place the cross mark in the 60~90 degree area (between
two red lines)
F. Press the ‘MEASU’button and check if‘A0 : ’color is changed.
G. Repeat from Step E to F for the other areas
H. Press‘SAVE button
I. Repeat from step C for 5and 10lenses.

2.5. The calibration of the cylindrical axis
With the +1.5D and -1.5D cylindrical lenses, we can calibrate the cylindrical axis
of the equipment. The procedures are as follows:
A. Press‘CYL SETUP’button.
B. Place the -1.5D cylindrical lens on the lens cap.
C. Using ‘-0.01’and‘+0.01’button, make lens value to the real value in the
standard model-eye specification.
D. Find lens center. I and D values cannot bigger than 0.03
E. Rotate lens until AXIS is in range 90±0.5
F. Press the ‘MEASU’
G. By rotating again, find other lens centers 135°/180°/45°and repeat from
step D to F
