DTNVS | L3Harris Unfilmed, White Phosphor 24UA

These built-to-order units have a lead time of typically 15 days or less. If more precise lead-time estimates are required, please contact us.

Complete System

• DTNVS with choice of L3Harris Unfilmed tubes are various performance minimums and spot specifications
• Full kit contains DTNVS with Milspec optics (Carson),  Apollo custom hard-sided case, objective lens covers, eyepiece covers, sacrificial windows, an Apollo Lens-Pen, cleaning wipes, decals and stickers, and a Surefire CR123a battery.
• Collimated, nitrogen purged, zeroed diopters, with focus stops set slightly past infinity.

Tubes

• The following L3Harris unfilmed white phosphor tubes are autogated and come with electromagnetic interference (EMI) shielding.
• Choice of Military or Aviator spot spec.
• Spot spec permits a maximum number of spots per zone that differs between military (ground) and aviation tubes.
• UM=unlimited FOM Military. UA=Unlimited FOM Aviation.
• Spots less than or equal to .003" (peppering) are permitted in any zone. A certain amount of peppering exists in all intensifier tube based night vision. Spots are a normal by-product of the manufacturing process
• UM permits spots larger than .003" in zone 2 and 3. UA permits spots larger than .003" in zone 3 only.
• Choice of minimum guaranteed performance (FOM / SNR). 

• 24UA, 36 SNR Min.  | Aviation spot spec: spots >.003" permitted in zone 3 only. | 24UA held to minimum 36 SNR (typically ~2600 FOM+)
  

DTNVS Description

Auto-shutoff flexibility: The DTNVS has a traditional on/off knob but also includes an auto-shutoff feature which engages when it senses that its been flipped up on a helmet, as well as independent pod auto-shutoff when each pod is rotated up.

Independent pod shutoff allows the user to rotate a single pod out of their line of sight (above their eye) which can be helpful when looking through a thermal scope. It may also be helpful if the user wants to use a single monocular (which also saves power). Additionally, by rotating both pods out of the way (as opposed to flipping the device onto the helmet), the user can quickly collapse both pods for fast use without needing to flip the goggle down from the helmet. This creates additional flexibility for moving in and out of tight spaces like vehicles, where the user might otherwise accidentally strike their goggles on a door frame or other object when flipped up.

The auto-shutoff feature is optional and can be disabled if the user has a preference for manual control or can't risk an accidental shutoff (fast-roping, climbing a ladder, etc.) 

Battery Life: The DTNVS uses a single CR123a battery which provides over 25 hours of run time - about 2x that of similar binocular night vision devices that use a AA battery. While some BNVD's with a AA battery include a battery port for an optional battery pack, the DTNVS does not, as its better on-board battery life didn't necessitate taking up additional space on the goggle for a connection port. 

Servicing / Maintenance Flexibility: Compared to proprietary or factory built BNVDs like the PVS-31A, the DTNVS uses PVS-14 style optics. As a result, the DTNVS includes an adjustable diopter to closely tailor the focus to the user's eyes (helpful for those that require corrective lenses). Additionally, it provides more flexibility for servicing the device (ex. replacing a scratched or damaged lens) or upgrading the lenses to a lightweight alternative. Inter-pupillary distance stops may be purchased separately and are easily installed (though the majority of users opt to use the device as-is, without them).

Streamlined approach: The DTNVS uses mx10160 format tubes which have automatic gain (brightness) that have become popular in binos like the RNVG and are used in a variety of other goggles such as the GPNVG, PVS-23, ANVIS 9, and others. Controls are simple and familiar: one knob for OFF->ON->IR.
