Photonis 4G Echo Green Phosphor PVS-14

Description

Echo green tubes with gain levels that exceed prior 4G requirements, but are not considered the ‘High Gain’ variant. These tubes have U.S. equivalent gain levels of 35,000-40,000. Current production commercial Gen 3 tubes allow for minimum 40,000 gain (but typically are 60,000+) for reference. 

Versatility

The PVS-14 is generally considered to be the most versatile night vision device available. They can be worn helmet mounted, hand-held, mounted to a telescope, camera, or other magnified optic for astronomy or surveillance. Their small size means they are easy to travel with and carry. They are small enough to fit in a GP pouch on a plate carrier without being obstructive.

Adjustable Gain
PVS-14s have variable gain adjustment and control.

Gain control gives the user the ability to increase or decrease the tube brightness.

Under extremely dark conditions, variable gain (also referred to as manual gain) allows the user to adjust the gain upward, giving a brighter image.

Under higher light conditions, the user can decrease the gain for a cleaner image or to prevent the washout of fine details in high light.

Additional features of the PVS-14 include an onboard IR illuminator and a red LED indicator light (light pipe) internal to the device (behind the tube) which signals IR is active or battery is low.

The PVS-14 allows the user to retain their night adapted vision in one eye while viewing their illuminated surroundings through eyepiece of the PVS-14. On the other hand, binocular night vision gives the user better depth perception, and if it includes articulation, the ability to also use a monocular similar to a PVS-14 (by rotating one pod out of the way).
