Handling
The VarioCAM®hr head is equipped with a highly sensitive uncooled microbolometer detector. Object
radiation occurring in thermographic practice does not cause any changes in the detector. However,
black-body radiation overdrive exceeding 1,000 °C in measuring ranges 1 and 2 or 2,000 °C in
measuring ranges 3 and 4, may result in irreversible damage and must therefore be avoided by
selecting a suitable calibration range* prior to measuring.
The VarioCAM®hr head must, neither in operation nor when switched off, directly be focused into the
sun or other sources of intensive radiation (e.g. lasers), since this may result in changes of the
microbolometer detector, whose origin can unambiguously be proven. The manufacturer waives any
warranty for such damage.
It is also imperative to avoid indirectly capturing any sunlight or other highly energetic radiation via
reflective surfaces directed into the field of view of the VarioCAM®hr head!
Under certain conditions, it cannot be excluded, even when the system is switched off, that the
detector may be damaged when directed into sunlight. Therefore, when the VarioCAM®hr head is not
in use, the lens must be capped with the protective cover included.
Only use SecureDigital cards in the SD slot of the VarioCAM®hr head. Otherwise damage to the
camera or the memory card can arise, for which no liability will be accepted.
Lens changes should not be carried out in rooms of high dust load or humidity, since IP 54 protection
class is not guaranteed with the lens removed.

3Technical Description
3.1 Operating Principle
The VarioCAM®hr head is a thermographic system for the long wave infrared spectral range (LWIR) of
(7.5 ... 14) µm. The lens images the object scene onto a microbolometer array at a resolution of
(640 x 480) or (384 x 288) pixels. The electrical signal of the detector arrays is further processed by the
internal electronics. The electronics contains all the functions necessary for camera operation, such as
activation of the microbolometer array, A/D conversion, offset and gain correction, defective pixel
treatment, video and PC interfaces.
Operating the system is effected via the PC interfaces, available as FireWire (IEEE 1394) and RS232*.
The use of these interfaces which are available depending on their versions of equipment requires special
software packages. You will find relevant details from Chapter 8 on, Hardware and Software Installation
for VarioCAM®hr head*, page 5.
3.2 Description of the Functional Units
Lens
The camera lens captures the IR radiation emitted by the object in the field of view and images it on the
detector array. Field of view (FOV) and resolution/size of the measuring point (IFOV, Instantaneous Field
of View) are determined at the same distance from the focal length f of the lens used.
The following standard lenses are available:
Thermographic system of resolution (384 x 288) pixels
lens focal length (mm) min. focus (m) IFOV (mrad) FOV (°)

Detector
The VarioCAM®hr head has an uncooled microbolometer FPA detector (uncooled Focal Plane Array).
The detector is thermally stabilised with high precision using a Peltier element and is thus independent of
the ambient temperature.
The various elements of the detector are microscopically minute thin-film resistors on wafer-thin
membranes, which are arranged cantilevered a few micrometers above the silicon read-out circuit. The
thermal radiation of the scene is imaged by the lens of the thermographic system on these detector
elements and absorbed by them. The temperature change of the detector elements resulting therefrom
yields electronically evaluable signals which can be read out line-wise and column-wise by a read-out
circuit.
Applying an uncooled detector guarantees quick availability of the camera function after switching it on
(start-up time < 60 seconds) and long service life (MTTF) in permanent use.
Detector electronics
The detector electronics supplies the BIAS voltages required for detector operation and further control
signals, and it takes care of the pre-processing and digitalisation of the analog video output signal from
the detector.
Image processing electronics
Real-time image processing with the following essential functions (depending on the equipment) is
implemenmted with the help of an FPGA (Field Programmable Gate Array) and an embedded PC
(modular compact internal PC):
■Detector electronics interface
■Gain and offset correction
■Defective pixel treatment
■Low-pass filtering
■Zoom generator
■Graphic overlay
■FireWire (IEEE 1394) interface
■Embedded PC interface
■Standard-format video-image generator (PAL/NTSC-FBAS, S-Video, RGB)

7.1 Using a Tripod*
For this purpose, the thermographic camera has a 1/4" tripod threat (DIN 4503) at the bottom. The
installation of the VarioCAM®hr head on a tripod (optional accessory) is recommended for blur-free
camera exposures, especially when using the Resolution Enhancement mode.
Please note the maximum screw-in depth of the photo thread of 4.5 mm (DIN 4503).
7.2 Connecting the Power Supply
The external power supply unit* is connected to the 14- pin socket situated on the left rear of the
thermographic system.
7.3 Inserting a Memory Card
The SD card slot is located on the left of the camera. It is protected by a cover to guarantee its IP 65
protection class. In order to insert the memory card, remove the cover and put the card into the slot.
Please ensure the correct orientation of the card (▲to the top). Then cover the slot again. This is
compulsory to maintain the full protection class of the device.
7.4 Lens Replacement
Only perform replacement of lenses in dry and as dust-free as possible environment. With the lens
removed, the system's IP 65 protection class is not guaranteed!
Place the VarioCAM®hr head on a solid, plane base with the lens facing to you. Turn the lens-fastening
ring clockwise until it stops (approx. 145°) and remove the lens to the front.
For fixing the lens, the red markings on the lens, on the lens-fastening ring and on the camera must be
aligned. The lettering on the lens will then face up. In this position, the lens is gently pushed against the
corpus of the camera; the lens-fastening ring is unlocked and automatically turns to the right. Finally, the
lens-fastening ring is fully locked by gently pushing it to the right.
