NVG-DTF (Daylight Training Filter for Night Vision Goggles and Monoculars)

Threads onto your night vision device’s objective lens to safely simulate nighttime conditions in daylight. Use with eye cups to truly simulate nighttime conditions.

The ENVS NVG-DTF (Daylight Training Filter) enables safe and effective daytime training with night vision goggles and monoculars—allowing users to practice in bright environments while maintaining the visual characteristics of low-light operations. Instructors can observe and guide trainees in full daylight, while operators experience realistic, darkened conditions that simulate authentic night vision use.

Designed to fit PVS-14 pattern optics, the NVG-DTF is compatible with a wide range of systems including the PVS-14, Argus BNVD, ACTinBlack DTNVS, etc.

Advantages Over Traditional Pinhole Covers

Realistic Depth Perception

Standard pinhole covers flatten the visual field by keeping all distances in focus, which doesn’t replicate real nighttime viewing. The NVG-DTF maintains true depth of field—distant objects remain clear while near objects appear naturally out of focus—mirroring authentic NVG performance.

Secure and Durable Mounting

Instead of a loose friction fit, the NVG-DTF threads directly onto the objective lens, staying firmly in place during physical activity, vibration, and impact.

The ENVS NVG-DTF is the professional solution for daytime NVG training, providing optical accuracy, secure attachment, and durability that surpasses legacy training filters.
