GEN3 IMAGE INTENSIFIER TUBE
The QCNV Q5 series of Gen3 image intensifier tubes amplifies available light to provide visible images in low-light environments. With green and white phosphor options, the series offers configuration choices for night vision device manufacturers and system integrators. Explore the specifications below to select a tube for your optical system and application requirements.
QCNV Q5 IIT
Key Features
Two Performance Grades
Choose Q5-B or Q5-A, with FOM ranges of 2,000–2,200 and 2,200–2,400, respectively. Resolution is specified at ≥64 lp/mm for Q5-B and ≥64/68 lp/mm for Q5-A.
Four Configuration Options
Available in 2-contact, 3-contact, pigtail cable and integrated-type configurations. Select the appropriate format to match your device’s mechanical and electrical requirements.
Green & White Phosphor
Choose P43 green phosphor or P45 white phosphor to suit your preferred image appearance and night vision system configuration.
Power Supply & Gain Options
Power supply options include auto-gating, with external gain or brightness adjustment options depending on the selected configuration.
Grade-Based Signal-to-Noise Ratio
Minimum SNR is ≥32 for Q5-B and ≥35 for Q5-A, providing defined performance levels for your low-light imaging requirements. Both grades use a Gen3 GaAs photocathode.
Wide Operating Temperature Range
Specified for operation from −45°C to +55°C and storage from −45°C to +70°C, with a tube weight of ≤75 g.
IIT Device & Setup Views
Explore Gen3 image intensifier tube layouts across monocular, dual-tube binocular, single-tube biocular, and panoramic night vision configurations.
Drawings illustrate different night vision configurations. Please confirm tube format, electrical interface, and device compatibility before ordering.
