Exosens 4G+ Image Intensifier Tube

P45 white backorders: If out of stock, you can still order. Please allow 4–5 weeks for dispatch. P43 green remains available by enquiry only.

Manufacturer: Exosens (formerly Photonis).

Exosens 4G+ is a premium image intensifier tube designed for exceptional performance across challenging and rapidly changing low-light environments.

Positioned above 4G, the 4G+ range combines a minimum Figure of Merit (FOM) of 2300 with very fast auto-gating, extended spectral sensitivity and a reduced halo around bright light sources. This helps preserve image detail and contrast in both extremely dark and dynamically lit conditions.

Choosing your tube

Select P45 white phosphor above to view pricing and availability. P43 green phosphor is available by enquiry only. Both options use the 18 mm 10160-style, three-contact EGAC format. Please confirm compatibility with your night-vision device before ordering, or contact Deep Dark if you need assistance.

Tube format and gain control

This is an 18 mm 10160-style tube with three contact pads. The centre contact provides external gain control through a 180 kΩ EGAC circuit when used in a compatible three-contact device.

It can also be installed in a compatible standard two-contact device. In that configuration, the centre contact remains unconnected and the tube operates without user-adjustable manual gain, using its automatic brightness-control functions.

Please contact Deep Dark with your device manufacturer and model if you are unsure about compatibility.
