OVERVIEWKEY FEATURESThe R941 compact zoom camera from Mirion has
been developed to provide a radiation tolerant
zoom facility in a compact 55mm diameter case.
The zoom facility comprises a non-browning 8 to24mm, f/2.8 to f/16 zoom lens with all the optical
functions (ie, focus, zoom, iris and macro) fully
motorized to allow complete remote control via theR90 Mk 3 Camera Control Unit. Housed in a stainlesssteel case the R941 camera incorporates a zoom
lens that can focus and track from 50mm to infinity.

••••The R941 camera is designed to be used inconjunction with Mirion’s R90 Series Mk 3 Camera
Control Units. Fully compatible with international
video standards, R90 Mk 3 Control Units can beintegrated or locked to external sources, image
processors or machine vision systems. A range of
portable or rack mounted versions are available withlocal control, or remote control over twisted pair orvideo coaxial cables.

A “good” picture is defined as one where theillumination available is sufficient for the camera toproduce a 1 volt composite video signal with a fully
open aperture.
A “usable” picture can usually be obtained,
dependent on the scene viewed and environmental
factors, etc, when the illumination available is only one
third that required to achieve a 1 volt composite video
signal at full aperture.
Mirion Technologies should be consulted to very
critical viewing requirements, or in cases where there
are important lighting, resolution, environmental orviewing angle considerations.
In applications where there are severe spaceconstraints care should be taken to allow for the size ofthe camera cable mating connector and if necessary,the bend radius of the connecting camera cable.
Please refer to the R90 series cables and connectors
data sheets.
Mirion Technologies should be consulted if longer
cable lengths are required.
