Laser filters
« on: September 15, 2018, 01:54:08 PM »
I would like to use the knowlege of the forum members to learn more about laser filters.
In Sweden, to my knowlege, only one binocular has been issued with laser filters. It is the Swarovski 7x42B. It is a special model built for the Swedish navy. The binocular has blue rubber protection. The only Swarovski 7x42B issued in this colour?

The Zeiss 7x50B in its different models has also seen service in Sweden. In the navy and in the army as well. There was some experiments with laser filters on 7x50 BGA (se picture). But the model was not issued with laser filters.
"Försöksmodell"= test model.
I know the Zeiss 7x50B saw use in the British navy. Did they have laser filters?
In Germany the similar 10x50B was used in the Bundeswehr. Did they have laser filters?
I think the Bundesmarine used the 7x50B in green rubber, but I am not sure. Laser filters?

Any knowlege about laser filters on binoculars in other countries?

The US Army Fujinon M22 7x50 and Apache M24 roof prism binoculars have laser filters as do the Australian Army Fujinon 6x30's.

I'm not aware of laser filtered Zeiss biinoculars used with the Royal Navy but the Avimo Mariner has them; ;)

Thank you Niall for your input.
I have never seen those Avimo Mariner before, they look awesome.
Are they Porro 2?

They do seem quite rare Robert - I've only come across two pair in years of collecting. They are Porro2 and seem to be based on the Barr and Stroud Porro2's of the 1930's. The 7x42 format was issued to Fleet Air Arm observers for use in aircraft in the Royal Navy - probably because the more common 7x50 was too cumbersome for use in an aircraft.

On saying that, Fleet Air Arm observers in open cockpit Fairey Swordfish biplanes ("Stringbags") are known to have used the bigger 7x50 too though;

Dear Robert,

also the Hensoldt 8x30 M Fero-D 16 is equipped with an anti-laser filter (laserschutz).

I know that it's possible find also D16 without filter, but I don't know if were made without, or if the filter was removed.

Perhaps it was removed to eliminate an obstacle to the passage of light, and improve its visibility?

I think they were all made with filters but I may be wrong Rodolfo.
