ICX085AK
Diagonal 11mm (Type 2/3) Progressive Scan CCD Image Sensor with Square Pixel for Color Cameras
Description
The ICX085AK is a diagonal 11mm (Type 2/3)
interline CCD solid-state image sensor with a square
pixel array. Progressive scan allows all pixels
signals to be output independently within
approximately 1/12 second. This chip features an
electronic shutter with variable charge-storage time
which makes it possible to realize full-frame still
image without a mechanical shutter. High resolution
and high color reproductivity are achieved through
the use of R, G, B primary color mosaic filters.
Further, high sensitivity and low dark current are
achieved through the adoption of HAD (HoleAccumulation Diode) sensors.
This chip is suitable for image input applications
such as still cameras which require high resolution.

Definition of standard imaging conditions
1) Standard imaging condition I :
Use a pattern box (luminance 706cd/m2, color temperature of 3200K halogen source ) as a subject.
(Pattern for evaluation is not applicable.) Use a testing standard lens with CM500S (t = 1.0mm) as an IR
cut filter and image at F5.6. The luminous intensity to the sensor receiving surface at this point is defined
as the standard sensitivity testing luminous intensity.
2) Standard imaging condition II :
Image a light source (color temperature of 3200K) with a uniformity of brightness within 2% at all angles.
Use a testing standard lens with CM500S (t = 1.0mm) as an IR cut filter. The luminous intensity is adjusted
to the value indicated in each testing item by the lens diaphragm.
1. G sensitivity, sensitivity comparison
Set to standard imaging condition I. After selecting the electronic shutter mode with a shutter speed of
1/80s, measure the signal outputs (VGr, VGb, VR and VB) at the center of each Gr, Gb, R and B channel
screens, and substitute the values into the following formula.
VG = (VGr + VGb)/2
Sg = VG × 80 [mV]
12
Rr = VR/VG
Rb = VB/VG
2. Saturation signal
Set to standard imaging condition II. After adjusting the luminous intensity to 10 times the intensity with the
average value of the Gr signal output, 150mV, measure the minimum values of the Gr, Gb, R and B signal
outputs.
3. Smear
Set to standard imaging condition II. With the lens diaphragm at F5.6 to F8, first adjust the average value
of the Gr signal output to 150mV. Measure the average values of the Gr signal output, Gb signal output, R
signal output and B signal output (Gra, Gba, Ra and Ba), and then adjust the luminous intensity to 500
times the intensity with average value of the Gr signal output, 150mV. After the readout clock is stopped
and the charge drain is executed by the electronic shutter at the respective H blankings, measure the
maximum value (VSm [mV]), independent of the Gr, Gb, R and B signal outputs, and substitute the values
into the following formula.
Sm = VSm ÷
Gra + Gba + Ra + Ba

4. Video signal shading
Set to standard imaging condition II. With the lens diaphragm at F5.6 to F8, adjust the luminous intensity
so that the average value of the Gr signal output is 150mV. Then measure the maximum (Grmax [mV])
and minimum (Grmin [mV]) values of the Gr signal output and substitute the values into the following
formula.
SHg = (Grmax – Grmin)/150 × 100 [%]

ICX085AK
5. Uniformity between video signal channels
After measuring 4, measure the maximum (Rmax [mV]) and minimum (Rmin [mV]) values of the R signal
and the maximum (Bmax [mV]) and minimum (Bmin [mV]) values of the B signal, and substitute the values
into the following formula.
∆Srg = (Rmax – Rmin)/150 × 100 [%]
∆Sbg = (Bmax – Bmin)/150 × 100 [%]
6. Dark signal
Measure the average value of the signal output (Vdt [mV]) with the device ambient temperature 60°C and
the device in the light-obstructed state, using the horizontal idle transfer level as a reference.
7. Dark signal shading
After measuring 6, measure the maximum (Vdmax [mV]) and minimum (Vdmin [mV]) values of the dark
signal output and substitute the values into the following formula.
∆Vdt = Vdmax – Vdmin [mV]
8. Line crawl
Set to standard imaging condition II. Adjust the luminous intensity so that the average value of the Gr
signal output is 150mV, and then insert R, G, and B filters and measure the difference between G signal
lines (∆Glr, ∆Glg, ∆Glb [mV]) as well as the average value of the G signal output (Gar, Gag, Gab).
Substitute the values into the following formula.
Lci = ∆Gli × 100 [%] (i = r, g, b)

9. Lag
Adjust the Gr signal output value generated by strobe light to 150mV. After setting the strobe light so that
it strobes with the following timing, measure the residual signal (Vlag). Substitute the value into the
following formula.

Notes on Handling
1) Static charge prevention
CCD image sensors are easily damaged by static discharge. Before handling be sure to take the following
protective measures.
a) Either handle bare handed or use non-chargeable gloves, clothes or material. Also use conductive shoes.
b) When handling directly use an earth band.
c) Install a conductive mat on the floor or working table to prevent the generation of static electricity.
d) Ionized air is recommended for discharge when handling CCD image sensor.
e) For the shipment of mounted substrates, use boxes treated for the prevention of static charges.
2) Soldering
a) Make sure the package temperature does not exceed 80°C.
b) Solder dipping in a mounting furnace causes damage to the glass and other defects. Use a ground 30W
soldering iron and solder each pin in less than 2 seconds. For repairs and remount, cool sufficiently.
c) To dismount an image sensor, do not use a solder suction equipment. When using an electric
desoldering tool, use a thermal controller of the zero cross On/Off type and connect it to ground.
3) Dust and dirt protection
Image sensors are packed and delivered by taking care of protecting its glass plates from harmful dust and
dirt. Clean glass plates with the following operation as required, and use them.
a) Operate in clean environments (around class 1000 is appropriate).
b) Do not either touch glass plates by hand or have any object come in contact with glass surfaces. Should
dirt stick to a glass surface, blow it off with an air blower. (For dirt stuck through static electricity ionized
air is recommended.)
c) Clean with a cotton bud and ethyl alcohol if the grease stained. Be careful not to scratch the glass.
d) Keep in a case to protect from dust and dirt. To prevent dew condensation, preheat or precool when
moving to a room with great temperature differences.
e) When a protective tape is applied before shipping, just before use remove the tape applied for
electrostatic protection. Do not reuse the tape.
4) Do not expose to strong light (sun rays) for long periods, color filters will be discolored. When high
luminance objects are imaged with the exposure level control by electronic-iris, the luminance of the imageplane may become excessive and discolor of the color filter will possibly be accelerated. In such a case, it is
advisable that taking-lens with the automatic-iris and closing of the shutter during the power-off mode
should be properly arranged. For continuous using under cruel condition exceeding the normal using
condition, consult our company.
5) Exposure to high temperature or humidity will affect the characteristics. Accordingly avoid storage or usage
in such conditions.
6) CCD image sensors are precise optical equipment that should not be subject to too much mechanical
shocks.
