2Advice on Device Safety

General

The VarioCAM®hr head is a high-quality, thoroughly calibrated optical measuring instrument. Handle it

with appropriate care. Avoid soiling it, particularly its optical surfaces.

The device has protection class IP 65.

Please observe the conditions specified under Technical Data (see Chapter 3.3, Technical Data, page 9)

for use, save and transport of the device.

For transporting the VarioCAM®hr head, exclusively use the transportation case included.

Opening the camera case is reserved for customer service or authorised staff only. Any interference by

the user or unauthorised persons is not permitted and will void any warranty.

Only use accessories or spare parts which are expressly recommended by JENOPTIK Laser, Optik,

Systeme GmbH for use with the VarioCAM®hr head. Otherwise malfunctions or damage can occur.

Warranty shall be excluded for such damage.

Standards, Guidelines

The VarioCAM®hr head complies with the requirements of the following standards:

■EN 61010-1:2001 Safety requirements for electrical equipment for measurement, control and

laboratory use – Part1: General requirements (IEC 61010-1:2011)

■EN 61326-1:2006 Electrical equipment for measurement, control and laboratory use – EMC

Requirements – Part1: General requirements (IEC 61326-1:2005)

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 (°)

wide-angle lens 12.5 0.2 2.8 (57 x 44)

telephoto lens 1 50 2.0 0.7 (15 x 12)

telephoto lens 2 75 2.0 0.47 (10 x 8)

telephoto lens 3 130 5.0 0.27 (6 x 4)

close-up lens focal length (mm) focus (mm) field of view (mm²) resolution (μm)

close-up 0.5x for 25 50 (27 x 20) 70

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)
