MX10160 is the designation for a specification for image intensifier tubes for the United States military.
The designation is often used to refer to the format of the tube specified inside of the specification, as all iterations of the specification reuse the same format to facilitate backwards compatibility.
Other names commonly used to refer to the format are Small Anvis (because it was developed for AN/AVS-6 binoculars) and 18 mm (because the built-in microchannel wafer has a diameter of 18 millimeters).
Iterations
MX10160
The original MX10160/AVS-6 specification was introduced in 1997 in the MIL-I-49428 specification. [1]
