This is a video of MATBOCK’s Tarsier Eclipse in action. The Tarsier Eclipse is an accessory for NVGs designed to allow the operator to see objects from 18″ to infinity at the same time and without loss of clarity. It incorporates a smooth action, high performance optical iris that can quickly be adjust open or closed depending on the amount of ambient light. Additionally, the clear front Corning Glass sacrificial lens can quickly be replaced without tools.
The Tarsier Eclipse is designed to fit the following models of NVGs:
-AN/PVS-7
-AN/PVS-7B/D
-ANVIS-9
-AN/PVS-14
-NEPVS-14
-AN/PVS-15
-AN/PVS-18
-AN/PVS-23 (F5050YG)
-AN/PVS-31 BNVD
The video was taken by I^2Technologies and Systems Integrations.

Looks cool. Lowering the aperture always leading to less light hitting the photomultiplier or light sensor (depending on technology).
Here we could clearly see, that it does not affect the visibility at all. I’m wondering, what is the actual trade-off? Maybe, a bit higher power consumption?
There is not always a trade off
We can’t beat the physics of image intensification process.
In given lighting conditions, smaller aperture leads to less light on the photocatode of image intensifier. Less light means more electrons needed to be consumed to intensify the resulting image.
Can’t wait to test this theory. “Nods A died one Nanosecond before Nods B, verifying the fact that image intensification is still subject to the laws of chemistry”
Ill let you know the results, fancy talking science man.
