cnder III – User Guide – 01/2017
1.3. Safety precautions using class 1 and class 2 lasers
cnder III uses an invisible class 1 laser for distance measurement and a visible class 2 laser as a
pointer (alignment laser). The invisible class 1 laser used for measuring is based on the norm
EN 60825-1:2015. Therefore, it will not cause any damage to the human eye. The visible class 2
alignment laser is equivalent to the norm IEC825-1/DIN EN 60825-1:2015 and similar to a laser class 2
based on FDA 21 CFR.
Damage to the human eye is possible if exposed directly for an extended period of time. Whenever the
eye is exposed to this laser, the bodyʼs natural reex is to close the eyelid as quickly as possible.
However, this reex can be aected by pharmaceuticals, alcohol or drugs. Under regular working
conditions no additional safety precautions are necessary. Do not stare into any laser radiation source(s)
or shine into the eyes of others. It is safe to view a diuse-reected beam.
Do not dismantle the unit in any way. Doing so may expose laser radiation in excess of class 1,
class 1M, class 2 or class 2M limits respectively.
Warning:
Always avoid direct eye contact with the beam of the red alignment laser. Staring into the visible
class 2 laser may cause permanent eye damage.
Note:
Depending on camera manufacturer and in rare disadvantageous angle where the measuring laser could
bounce back into the lens if shooting reective surfaces, the reection of the invisible class 1 laser´s
measusring spot might be visible in camera.

2. Component overview
2.1. cnder III
2.1.1. Main component overview
cnder III is an optical distance measurement tool that works with an invisible class 1 laser. The
laser has a measurement range of 1 m – 150 m (approx. 3.3 – 492 ft) and an accuracy range of less
than +/- 5 cm (approx. +/- 2 inches) (depending on environmental conditions / target surface, color
and reectivity).
A visible class 2 laser (alignment laser) is used to visualize the relative position of the invisible
class 1 laser‘s measuring spot.

2.2. Reector sight
2.2.1. Main component overview
The reector sight uses a small light which is projected onto a curved semi-transparent mirror.
From there the light is reected towards the operators eye. The reector sight can be attached to
the NATO rail of cnder III easily (Allen key, size 3 mm required). For further operation the target
mark (red/green spot) of the reector sight needs to be aligned to the measuring laser which is
represented by the visible alignment laser of cnder III. After alignment the operator can target and
track objects easily referring to the superimposed marker within the reector sight while lming.
Note:
This red/green spot reected from the semi-transparent mirror is not harmful to the human eye and
can be watched without any safety precautions.

5. System set-up and operation
5.1. Aligning the reector sight to cnder III using the internal target mark
1. mount the reector sight to the NATO rail of cnder III (Allen key, size 3 mm required)
2. remove the protective caps for the pan and tilt adjustment wheel of the reector sight
3. activate a target mark by turning the rotary switch of the reector sight
4. activate the alignment laser of cnder III
5. turn the pan adjustment wheel (left/right) until the target mark matches the laser spot
projected by the alignment laser horizontally (athead screwdriver required)
6. turn the tilt adjustment wheel (left/right) until the target mark matches the laser spot
projected by the alignment laser vertically (athead screwdriver required)
7. replace on the protective caps for the pan and tilt adjustment wheel of the reector sight
Note:
Projecting the alignment laser onto a target as far away as possible improves the alignment if tracking
far distance objects. Nevertheless, aligning onto a far distance target creates a small vertical parallax
between the target mark of the reector sight and the actual position of the measuring laser spot of
approx. 6,5 cm (approx. 2.5 inches) in close distance.
Due to light conditions the laser spot of the alignment laser might not be visible in far distance. In order
to be independent of light conditions you can align the reector sight using the sensor feedback of
cnder III or cdistance (if available). (please refer to section 6.2.1. in this manual)
5.2. Mounting cnder III on the camera
Common fastening tools can be used to mount cnder III to the camera. Optional fastening tools are
available from cmotion.
• in order to avoid horizontal parallax, mount cnder III centered along the optical axis, above
or below the camera lens.
• in order to minimize vertical parallax, mount cnder III as close as possible to the lens
vertically
Note:
Minor horizontal or vertical osets relative to the optical axis will not cause signicant parallax hence
measurement precision. Nevertheless, parallax may cause issues when tracking a precise object from
far to close.
cnder III can be mounted along the optical axis of the lens, behind or in front of the camera‘s sensor
plane. This oset can be compensated using the oset function in the systems menu.
Warning:
In order to allow smooth operation, the measuring laser should not be blocked by any camera
parts or accessories. Especially if you want to cover a range from far to close distance, we recommend
to mount cnder III in line with the matte box.
page 17/24
cnder III – User Guide – 01/2017
5.3. Aligning cnder III to the optical axis of the lens
5.3.1. Using the reector sight
1. align the reector sight to cnder III (please refer to section 5.1. or 6.2.1. in this
manual)
2. activate a target mark by turning the rotary switch of the reector sight
3. activate a center cross on your camera
4. if using a zoom lens, zoom in all the way
5. aim your camera at a far-away target
6. slightly pan/tilt cnder III until the target mark of the reector sight matches the
same point as the center cross on your camera
5.3.2. Using the alignment laser
1. activate the alignment laser of cnder III
2. activate a center cross on your camera
3. if using a zoom lens, zoom in all the way
4. aim your camera at a far-away target
5. slightly pan/tilt cnder III until the spot of the alignment laser matches the same
point as the center cross on your camera
Note:
Due to light conditions the laser spot of the alignment laser might not be visible in far distance. In
order to be independent of light conditions you can align cnder III to the optical axis of the lens
using its sensor feedback or the sensor feedback of cdistance (if available). (please refer to section
6.2.2. in this manual)
All methods described above are aligning the measuring laser to the center of the lens. Under
certain circumstances you may want the measuring laser to be o center. If so, please align cnder
III accordingly.
Aligning onto a far distance object improves the alignment if tracking far distance targets.
Nevertheless, aligning onto a far distance target creates a small vertical parallax between the center
cross and the actual position of the measuring laser in close distance. Although this parallax will
not have any signicant eect on the measurement precision, it may cause issues when tracking a
precise object from far to close.
5.4. Using cnder III separate from the camera
cnder III can be used on a tripod separate from the camera. In this conguration the operator can pan
and tilt cnder III independently from the camera to track a moving target. In order to give the operator
reference of the lasers measuring spot you should use cnder III with the reector sight in this
conguration only (please refer to section 5.1. or 6.2.1. in this manual).
Note:
The tripod does not need to be positioned in line with the lm plane. This oset can be compensated
using the oset function within the systems menu (please refer to section 6.1.1. in this manual).
Although in this conguration the risk of vertical parallax can be eliminated by mounting cnder III at the
same height as the camera lens, keeping cnder III as close to the lens as possible will reduce the risk
of horizontal parallax.

cnder III – User Guide – 01/2017
6. Practical system operation
6.1. System settings
6.1.1. Oset
The oset function allows you to consider the dierence between the mounting point of cnder III
and the sensor plane of the camera.
• measure the distance from the datum line of cnder III to the sensor plane of your camera
• enter the measured distance into the cnder III oset menu
• if cnder III is mounted in front of the sensor plane enter positive values
• if cnder III is mounted behind the sensor plane enter negative values
6.1.2. Limits
The limit function allows you to dene your range of interest. If in AF mode, focus will be adjusted
for this range only.
limit max:
• use selection wheel to enter a far distance limit
• if in AF mode, focus will not be adjusted for measurements beyond this limit
limit min:
• use selection wheel to enter a close distance limit
• if in AF mode, focus will not be adjusted for measurements below this limit
The second screen overlay will show “limit“ if any limits other than default values (limit min=0, limit
max=inf) are set. Tacho view visualizes the set limit range by a bright green scale.
6.1.3. Sensitivity
The invisible laser used in cnder III makes 300 measurements every second. To make this rapid di-
stance information more suitable for both viewing and motorised lens control, cnder III calculates
an average distance that is then displayed on the screen and used to control the focus motor when
autofocus is active.
Sensitivity allows you to increase or decrease the rate at which the ‚average‘ value is calculated.
By increasing sensitivity, cnder III will display an increased number of distance values per second
and adjust the motor position accordingly (= faster / snap reaction).
By decreasing sensitivity, cnder III will display fewer distance values per second and adjust the
motor position accordingly (= slower / smoother reaction).
Note: To track a fast moving target, increase sensitivity for a faster motor response. To track a slow
moving or xed target, reduce sensitivity for a smoother motor response.
page 19/24
cnder III – User Guide – 01/2017
6.1.4. Autofocus
The autofocus function will seamlessly match distance measurement data from the cnder III with
lens data from the camin to control the focus scale of the lens automatically.
If autofocus “on“ is selected within the cnder III menu, focus will be adjusted permanently until
turned o again.
Autofocus can be activated through a cvolution hand unit as well. Using a cvolution hand unit
various autofocus trigger options including toggle and mark are available. (For further information,
please refer to the latest cvolution user guide)
Note:
In order to use autofocus with a cvolution system, a lens le needs to be loaded in the camin,
a lens motor needs to be connected, engaged with the lens and assigned to focus. For further
information on how to create lens data, please refer to the cvolution user guide and the cworld user

Due to light conditions the laser spot of the alignment laser might not be visible in far distance. In
order to be independent of light conditions you can use the cnder III sensor feedback to align the
reector sight to cnder III as well as to align cnder III to the optical axis of the lens. cdistance (if
available) shows the same sensor feedback and can be used for these practical alignment methods
as well.
6.2.1. Aligning the reector sight to cnder III using the sensor feedback
1. mount the reector sight to the NATO rail of cnder III (Allen key, size 3 mm required)
2. mount cnder III onto a camera tripod
3. remove the protective caps of the reector sight
4. activate a target mark by turning the rotary switch of the reector sight
5. aim at a xed horizontal and vertical target as far away as possible but within the range
of cnder III (e.g. aim the tip of a building against the sky)
6. pan the tripod head until the sensor does not get any feedback, measuring out of
range (e.g. hitting the sky)
7. pan back slightly until you have a rst measurement from the target (e.g. vertical
edge of the building) and x the pan axis of your tripod head
8. turn the pan adjustment wheel of the reector sight (left/right) until the target mark
matches your target horizontally (e.g. vertical edge of the building) (athead
screwdriver required)
9. tilt the tripod head until the sensor does not get any feedback, measuring out of
range (e.g. hitting the sky)
10. tilt back slightly until you have a rst measurement from the target (e.g. horizontal
edge of the building) and x the tilt axis of your tripod head
11. turn the tilt adjustment wheel of the reector sight (left/right) until the target mark
matches your target vertically (e.g. horizontal edge of the building) (athead
screwdriver required)
12. replace the protective caps of the reector sight

6.2.2. Aligning cnder III to the optical axis of the lens using the sensor feedback
1. activate a center cross on your camera
2. if using a zoom lens, zoom in all the way
3. aim at a xed horizontal and vertical target as far away as possible but within the range
of cnder III (e.g. the tip of a building against the sky)
4. once the center cross of your camera is matching the horizontal and vertical edges
of your target, lock your camera tripod
5. pan cnder III until the sensor does not get any feedback, measuring out of range
(e.g. hitting the sky)
6. pan cnder III back slightly until you have a rst measurement from the target
(e.g. vertical edge of the building)
7. tilt cnder III until the sensor does not get any feedback, measuring out of range
(e.g. hitting the sky)
8. tilt cnder III back slightly until you have a rst measurement from the target
(e.g. horizontal edge of the building)
9. Lock o the cnder III fastening tool
6.3. Maintenance
If not in use, cnder III should be kept in a clean and dry place.
The front lenses of cnder III are optical elements and should be treated as such.
The lenses should be kept dry and dust free.
In order to avoid scratching the lenses always remove dust with compressed air before cleaning with a
soft cloth.
