Opto-mechanics
The following functions are performed with the help of the opto-mechanics assembly group:
■
Focussing (motor focus)
■
Effective range change-over (lens apertures)

■
Internal

Furthermore, this assembly group has an optional module for a hardware-based increase of geometric
resolution of the thermographic system onto (768 x 576) IR pixels (detector of [384 x 288] pixels) and
onto (1,280 x 960) IR pixels (detector of [640 x 480] pixels): mode “Resolution Enhancement”*. The opto-
mechanics can be modified for reducing the minimal focus distance*.
Controls
VarioCAM
®
hr head is mainly designed for stationary applications. For those case of operation the
camera is operated from a host computer, via the FireWire (IEEE 1394)-Interface of the device. The
relevant operating software is also described in Chapter 8 Hardware and Software Installation for
VarioCAM® hr head* – page 22.
Power supply
The VarioCAM
®
hr head has the following power supply options:
■
External power supply unit 12 V*
■
FireWire (IEEE 1394) interface*.
The mains adapter is connected to the 14-pin (left) socket at the rear of the camera.
For devices equipped with a FireWire (IEEE 1394) interface, the supply voltage can be taken directly from
the PC interface card. Please note the specification of the used interface card and the power input of the
thermographic system. In case of cable lengths > 5 m, power should principally be supplied via the
external power supply unit or the rechargeable battery.
