    Night Vision Luna elir3 visible to coyotes?

    I believe both deer and coyote's can see the emission from the Luna ELIR-3. With full spectrum camera's the output of the ELIR-3 appears orange. Jay of SureShot Night Vision has a nice photo of this orange beam on instagram: Here's a screen grab from a video of the ELIR-3 next to an...

    Night Vision Need Knowledge on the M644 & M646

    The one that would thread on has fine threads just about a third of the way from the output end. It also isn't stepped like the pictured one, more of a taper. The rear element is also larger. I swear Jamison (NAIT) was selling the lenses a while back. I'd also hit up Jason Crum of Ident Marking.

    Night Vision Need Knowledge on the M644 & M646

    That lens, as configured, is not for the M646 The mechanical interface of that lens is for the ITT NQ6010/Star-Tron MK-880. Don't believe this can be swapped over. I'd contact NAIT and Nightline.

    Night Vision L3 'Smart' Part Number Cypher Keys

    Not to many years ago there were a couple batches of "commercial", unfilmed, non-gated tubes. Remember thinking they were a bargain. I ping Rich over at UNV or try L3 direct. 11769UG-ND-C001-18UM would decipher to unfilmed, P43(G), non-gated but maybe 🤡 world has affected part numbers and...

    PVS 14 adapter for Hensoldt Spotter 60

    To step down from male T-mount to female PVS-14 objective thread, this adapter from RAFCAMERA will be invaluable. A standard 42mm-to-30mm step down ring can work, the threads on the 14 side aren't quite a match, will grab but wouldn't trust it.

    PVS 14 adapter for Hensoldt Spotter 60

    This may not work for all but I use a Novagrade adapter for eyepiece connections.

    Night Vision L3 Unfilmed vs Photonis Echo

    Aperture disk fixed it at f/2.8 but if you remove the 3 screws on the back end, just behind the c-mount adapter, you can pop the lens in half and remove the aperture disk. This will get you the maximum aperture of f/1.8, well worth doing.

    Night Vision L3 Unfilmed WP Weird Ghosting Issue.

    Sure wouldn't be a bad idea as any nitrogen or argon will be lost.

    Night Vision L3 Unfilmed WP Weird Ghosting Issue.

    Yes, the battery / PS containing component. Swap the lowers between the two units. Put the lower on from the tube that's not exhibiting the effect onto the upper with the affected tube and vis versa. Don't think I'd bother with the whomever you've been working with. Yea it may be a comped...

    Night Vision L3 Unfilmed WP Weird Ghosting Issue.

    Yes, thank you, I should have said this effect is a characteristic of MCP image intensifiers as apposed describing it as normal. While the effect is a characteristic of MCP tubes, the manufactures do try to minimize it. I've seen the effect creeping back in as manufacturers tweak MCP processing...

    Night Vision L3 Unfilmed WP Weird Ghosting Issue.

    Occures at a dark/bright interface and movement causes a traveling wave at the boundary? Sounds totally normal and is related to the resistance of the micro channel plate. So seems you have a totally normal and temporal traveling wave effect. If you quickly oscillate the units FoV at the...

    Night Vision Average L3 Filmless Specs?

    Thought NVDevices contracted with RPO for the optics on their UL line and that the Ether was also with them.

    Night Vision Lense coating question(PVS-14 vs Glasses)

    Through pairing transition lenses with your 14, you've effectively turned your glasses into NV sunglasses. Just avoid photochromatic lenses when pairing with your WP unit, the chromaticity of your tube is activating the photochromic molecules in your transition lenses, just like UV-Vis does...

    Night Vision Sionyx?

    With a greater than 65% illuminated lunar disk or introduced illumination from either IR or white light, you probably can't do better, at least on a new ready to go system. Forget 60fps at anything lower than a 90% illuminated lunar disk, 30fps it will be. and below 35% your in 15fps and 7.5fps...
