Matte hardcoat anodized, the lens adapter offers matte box-levels of performance between the night vision eyepiece lens and the host camera's lens for the best possible photo- and videographic results.

The LDT calculator should not be substituted for direct LIDT testing of optics utilized in a given application where laser damage is a crucial parameter. Due to environmental variables such as molecular contamination, physical contamination, mounting stress, temperature, etc. most optics don't ever achieve their perfect calculated LDT. The LDT calculator scales by laser wavelength and pulse duration based on the nominal specification, it should be noted that while the equations scale fairly linearly in the nanosecond range, the damage mechanism changes from primarily thermal to electron field breakdown when switching to the picosecond scale for pulse duration. Finally, most optics will have specific regions with low laser damage thresholds due to material absorption, these include OH lines and lower UV wavelength ranges.

LDT specifications can be found on each product webpage under the Optical Damage Rating header of the Specifications tab. For further information on LDT, please refer to our Laser Damage Threshold technical note.

The Cold Harbour Cine-NV line of NVG Camera Adapters directly connects any milspec PVS-14 eyepiece to a variety of cinema, mirrorless, and DSLR lenses. By connecting the night vision device directly to the camera lens, any unwanted artifacts such as stray light, and optical deviations (shaking) between the recording lens and the night vision device are completely eliminated giving the most true-to-life rendition of what looking through a night vision device should look like. Offered in a variety of lens thread sizes to suit any photographer and videographer's existing lens suite, the Cine-NV Camera Adapter is made to provide the most secure, shortest optical distance to the host lens that only a direct-mount ring can provide, completely eliminating any vignetting. Direct mounting also allows for full eyepiece diopter travel to dial in optimal focus.

NOT compatible with L3 PVS-31A, GPNVG-18, Infiray Jerry14 and Jerry31, or Optronics Lenses (without additional adapters).

Note that while a lens may fit, specific focal lengths are most optimized for this purpose. We have found that focal lengths ranging from 24mm to 55mm to be best with optimal focal length to be around 28mm for full-frame (not APS-C) cameras. Cinema and other medium-format cameras should adjust accordingly.Do not over tighten, we suggest mounting the night vision device on the adapter ring BEFORE mounting the adapter to the camera lens to avoid the adapter ring binding to the camera lens.Tested to be fully compatible with the following PVS-14 pattern eyepieces: Noctis Technologies (formerly Carson Industries), Fujinon, Qioptiq, Salvo Engineering, RPO 2.0, 3.0, and Photonis Defense Boomslang eyepieces.
