VALDADA I.O.R. 7x40 MILITARY BINOCULARS WITH INFRARED FILTER - MILITARY SURPLUS ROMANIAN ARMY - LIKE NEW

The Romanian company I.O.R. optics has been producing quality optical products since the mid-1930s. During World War II, the company was recruited by German forces. During the war they produced a wide range of military optics. When Romania was absorbed into the Warsaw Pact, I.O.R. became an important supplier to military forces in the East. Together with Carl Zeiss, I.O.R. supplied military-grade optics throughout the Cold War.
The infrared filter present in this model is built into the binocular configuration and allows infrared radiation to be observed at night.
The IR system is a passive system, consisting of a screen, regeneration filter, and a screen actuator. The IR-sensitive screen is activated by a light source containing infrared radiation in its spectrum, which is perceived as bright spots. Activation of the screen takes between 7 and 20 minutes, depending on the source you use, and screens retain their ability to function for about 5-7 days.
IR binoculars are not a night vision device because the IR filter can only detect light in the infrared spectrum, for example, that produced by the active red beacon of a military car, which is not visible to the human eye.
Using binoculars with glasses is not recommended because the lenses of the glasses may scratch.

• A Vintage piece
  These binoculars were manufactured around 1980. Even when serviced or preserved carefully, optics of this age can develop signs of wear that aren’t always apparent until they’re handled or used. Over the decades, microscopic cracks in seals can admit tiny amounts of moisture, and lacquer or paint inside the barrels can oxidize or flake, producing dust or discoloration.
• External condition
  Although we clean each pair before shipping and grade them to the best of our ability, “very good, like new” in the vintage market allows for light handling marks. However, if the dirt on your unit exceeds that standard, we apologize for that oversight, some customers prefer to receive the binoculars as is, with the 80's dust on them.
• Internal haze and fungal growth
  Even nitrogen purging can lose its effectiveness over many years if seals degrade. Fungal spores are unfortunately common in older optics that have been exposed to humidity. Once they take hold on internal surfaces, they can be very difficult to remove without a full strip-and-clean service.
