GEN2+ IMAGE INTENSIFIER TUBE
The QCNV Q4 series of Gen2+ 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 Q4 IIT
Key Features
Three Performance Grades
Choose Q4-B, Q4-A or Q4-A+, with FOM ranges of 1,400–1,600, 1,600–1,800 and 1,800–2,000, respectively. All three grades offer resolution of ≥64 lp/mm.
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 non-gated and auto-gated versions, with external gain or brightness adjustment options depending on the selected configuration.
Grade-Based Signal-to-Noise Ratio
Minimum SNR is ≥22 for Q4-B, ≥25 for Q4-A and ≥29 for Q4-A+, providing defined performance levels for your low-light imaging requirements.
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 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.
