Night vision buying guide
Choose a PVS-14-format monocular by its fitted tube, phosphor colour, optics and working controls, not just the housing name.
A monocular should be chosen as a complete device rather than by generation name alone. FOM, signal-to-noise ratio, resolution, autogating, visible tube marks, optics and the supplied documentation all affect the buying decision.
Through-tube photographs help show image appearance and visible marks, but camera exposure, focus and ambient light affect the result. The NNVT6L product gallery includes a tube sheet photographed from one actual unit; it is not a promise that every unit has those exact measurements. The supplied tube is guaranteed to meet the listed minimum FOM.
PVS-14-format devices are our current monocular focus. Yaksa models are not part of our near-term range; existing owners can still contact us for support. Check each product page for current availability, price and package contents.
| Device | Tube | Confirmed details | Buying position |
|---|---|---|---|
| PVS-14 NNVT6L | GEN2+ white phosphor | FOM 1600-1800; minimum 1600. Yian optics, reinforced nylon housing, AA power, low/high IR | White phosphor with automatic gain; the housing's manual-gain control is inactive with this fitted tube |
| PVS-14 NNVT Gen 3 green | Gen 3 green phosphor | Approximately FOM 1600; pictured sheet records 1572. Autogated with ABC, ARGUS housing and Yi'an optics | Green phosphor with documented tube figures and automatic light handling |
| PVS-14 NNVT Gen 3 white | Gen 3 white phosphor | Separate FOM 1600 and FOM 1800 options; ARGUS housing and Yi'an optics | Choose the actual configuration. The photographed FOM 1800 sheet and its autogating/ABC figures do not establish the specification of the FOM 1600 option |
| Photonis Echo | GEN2+ white phosphor | FOM 1800, autogated, Photonis data sheet | Photonis tube platform in an ARGUS PVS-14 housing; check availability on the product page |
The current GEN2+ PVS-14 uses a glass-fibre-reinforced nylon housing, Yian optics and an NNVT6L automatic-gain tube. The side button selects low or high IR illumination. Do not select it for working manual gain: that housing control is inactive with the supplied tube.
View PVS-14 NNVT6LThe NNVT Gen 3 green configuration combines an ARGUS PVS-14 housing and Yi'an optics with autogating and automatic brightness control. Compare its individual tube sheet, rather than assuming the generation label guarantees a better image than every GEN2+ tube.
View Gen 3 green PVS-14FOM 1600 and FOM 1800 are separate options. Select the required specification and check which photographs and tube figures apply to it; a sheet for the FOM 1800 configuration is not the sheet for the FOM 1600 tube.
View Gen 3 white PVS-14The listed Echo configuration is GEN2+ white phosphor, approximately FOM 1800 and autogated. Compare the actual tube sheet and availability with the NNVT options.
View Photonis EchoFOM is resolution multiplied by signal-to-noise ratio. SNR indicates how clean the image remains as light falls. Resolution describes fine detail in lp/mm. Gain, EBI, halo and visible spots also affect the viewed image.
For the manufacturer's Echo range information, see the Exosens Echo product page.
Housing, optics, phosphor colour and tube class can be discussed before purchase. We confirm a custom build's preparation time and component availability before you order. This is separate from delivery time and does not replace the dispatch terms for an in-stock device.
Send the product links and your intended use. We can compare the listed tube data, condition and required accessories before purchase.
