OVERVIEWKEY FEATURESThe R940 compact zoom camera from Mirion has been•••••developed to provide a radiation tolerant zoom facility
in a compact 55 mm diameter case. The zoom facility
comprises a non-browning 22 to 90mm, f/3.5 to f/45 zoom
lens with all the optical functions (ie, focus, zoom, irisand where applicable macro) fully motorized to allow
complete remote control via the R90 Mk 3 Camera ControlUnit. Housed in a stainless steel case the R940 cameras
incorporate a zoom lens that can focus and track from50mm to infinity. This allows the version without macro
focus motor to suit most applications, but for applications
requiring very close focusing (less than 250 mm) the version
with macro focus motor can be supplied.
The R940 camera is designed to be used in conjunction
with R90 Series Mk 3 Camera Control Units. Fully
compatible with international video standards, R90 MK
3 Control Units can be integrated or locked to externalsources, image processors or machine vision systems. A
range of portable or rack mounted versions are available
with local control, or remote control over twisted pair orvideo coaxial cables. External lighting accessories areavailable.
For integrated system applications the R940 can easily beinterfaced with central switching units and remote control
panels. Control systems using PC driven SCADA control
techniques are also available.

1. The information regarding lighting ranges is approximate
only based on tests made in a darkroom viewing scenes
with reflectivitiy of 60% using an R940 camera fitted with anewvicon tube.
2. A “good” picture is defined as one where the illumination
available is sufficient for the camera to produce a 1 volt
composite video signal with a fully open aperture.
3. A “usable” picture can usually be obtained, dependent on
the scene viewed and environmental factors, etc, when theillumination available is only one third that required to achievea 1 volt composite video signal at full aperture.
4. Mirion Technologies should be consulted to very criticalviewing requirements, or in cases where there are importantlighting, resolution, environmental or viewing angle
considerations.
5. In applications where there are severe space constraints careshould be taken to allow for the size of the camera cablemating connector and if necessary, the bend radius of theconnecting camera cable. Please refer to the R90 series
cables and connectors data sheets.
6. Mirion Technologies should be consulted if longer cable
lengths are required.
