SPECIFICATION NOTES
1. 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 iris.
2. A “usable” picture can usually be obtained dependent on
the scene viewed and environmental factors etc, when the
illumination available is only 1/3 that required to achieve a
1 volt composite video signal with a fully open iris.
3. Mirion should be consulted with regard to very critical viewing
requirements, or in cases where there are important lighting,
resolution, environmental or viewing angle considerations.
4. In applications where there are severe space constraints care
should be taken to allow for the size of the camera cable
mating connector and, if necessary, the bend radius of the
connecting camera cable. Please refer to the IST-Rees R90 series
cables and connectors data sheet.
