Frequently Asked Questions

Question:  Why don't you include lens paper with your equipment?

Answer:  Lens paper tends to scratch the lens's Magnesium fluoride anti-reflection coating.  Over time these scratches dull the lens surface and eventually the lens would need to be replaced.  For Government issue, this is not a problem, but when my Customers are spending over $3,000.00 for my products, I want their lenses to last for decades.  I recommend using the same lens cleaning procedure I learned while in the USAF.  Click on the graphic below to download an Adobe.pdf that details proper lens cleaning.

Question:  Can night vision equipment go through the airport X-ray screening machines without getting damaged?

Answer:  Yes.  The X-ray screening machines do not harm American Made night vision equipment.  Thousands of ITT and L-3 scopes, monoculars, and goggles pass through these scanners every year with no damage observed or reported.

Question:  What does the Halo value have to do with a night vision device being weapons mounted?

Answer:  The Halo value of image tubes with an autogated power supply should be taken into consideration if the night vision device will be weapons mounted.  The Halo value is the diameter of the Halo seen around a point of light.  This Halo size is directly proportional to the distance the MicroChannel Plate (MCP) is from the PhotoCathode.  The lower the Halo value the shorter that distance is.  When an autogated tube is powered, the electrostatic fields between  the MCP and PhotoCathode change several thousand times per second between attracting and repelling each other.  The PhotoCathode is a very rigid structure that includes the corning glass faceplate, however, the MCP is roughly the size of a quarter made of glass having millions of small holes or channels in it.  As such the electrostatic forces flex the MCP's center towards and away from the PhotoCathode, which produces the distinctive whining noise coming from the equipment.  Recoil exacerbates this motion, so if the Halo value is too small the MCP will slam into the PhotoCathode causing damage seen as a large black spot.
