Rare soviet INP3-7/80A laser pumping flash tube.
Tested and 100% working.
Two tubes in one lot.
Every tube is carefully packaged before being shipped.
We guarantee that the tubes have not been used, but may have some signs of prolonged storage.
We do not ship these tubes in the original packaging because the tubes are long and can easily crack, and the original packaging is very unreliable, but gives extra weight and volume.
Also, after many years of storage, some packages look ugly.
There may be cracks in the glass at the edges of some tubes because there is a void at the edges of the tube between the glass and the metal.
When you receive the parcel, unpack the tubes very carefully and take your time!
We ship via International Airmail .
Tracking number is provided.
Important notice for buyers from Canada -shipping to central and western provinces of Canada may take up to 2 months!
Important information for buyers from Australia, Oceania, Central Africa and South America: due to increased shipping cost to these regions, shipping price is calculated individually.
The INP3-7 / 80A pulsed lamp with a straight glow body and foil current leads is designed for optical pumping of active elements of lasers. The INP3-7 80A lamp has a filtering coating that cuts off the ultraviolet part of the radiation spectrum. Electrical and radiation parameters upon delivery of the INP3 7 / 80A lamp
