DIPT-10A
The DIPT-10A is a passive French gen 2 binocular nvg adopted in the early 80's for the French army (army name OB-41A).
The binocular is multi use with its 33 degree's of field of view F1.0 optics and a minimal focus distance of 30 centimeters , the device weighs 1kg and has an integrated head mount.
The device is equipped with an integrated infrared diode to use only in absence of any lights, the device has a 3 position switch: Arret/off, Marche/on, and Lamp/light, the last position needs to have the rotative switch pushed slightly forward to be reach for avoiding accidental activation.
The device uses 2.7v BA1567 battery which gives it 20 hours of runtime or 10 hours if the infrared illuminator is always turned on. The gain is automatically regulated depending the light received in the tubes.
Sadly the model of the intensification tubes is unknown there are very few sources available, the existing ones talk about microchannel plate gen 2 tube.
The first prototypes of the device were made between 1973 and 74 and experimentations began between 1974 and 75.
Both oculars have diopter settings from -4 to +4.5 dioptries.
