Product information “Iris diaphragm for NT920/NT1431/PVS-14 standard lens”

Iris diaphragm for PVS-14/NT920/NT1431 standard lens. With sacrificial lens and cover.

The iris diaphragm can also be closed for improved depth of field. In exchange for light incidence, objects in the near and far range can be focused (similar effect to a pinhole cap).

The housing of the iris diaphragm is made of aluminum and can be mounted without tools. The thread diameter is 30.4 mm. Hole diameter from 1.5-22 mm.
