Estimant la distancia de l'enemic / Ranging the enemy distance

IN ENGLISH BELOW THE LINE

 

Els prismatics militars Huet de principis del s. XX son probablement uns dels més interessants que es poden trobar, i en general força bé de preu. La seva forma és bastant diferent dels més moderns, agafant un aire certament arcaic.

 

I sobretot és interessant el sistema de telemetria que porten incorporats els models per a infanteria i caballeria. En efecte, no tots els prismatics Huet porten aquest especial sistema. Es poden identificar clarament per 3 detalls: un selector en l'ullera dreta, unes plaques mostrant un soldat d'infanteria i caballeria a la part inferior, i el text I.C. (Infanterie & Cavalerie) abans del número de serie. Estan marcats també com a "7x".

 

El telemetre (que en aquest exemplar sembla funcionar prou bé) s'emprava així: amb la rodeta del selector es mou un cristall de calcita davant un dels ulls, amb el que la imatge que es veu queda com doble. Seguidament es mira quan s'ha separat una de les imatges de la part superior de l'enemic respecte a la del altre ull, i es consulta els gravats a aquest efecte que hi ha a sota els prismatics. Si per exemple hi ha tot un cap de diferencia, el soldat enemic està a uns 200 m., i si hi ha mig cos, a uns 700 m.

 

Hi ha un altre model de prismatics similars molt similar però de més magnificació ("8x") i sense el selector de calcita ni plaques de mesura. Era el model per artilleria i enginyers.

 

Ambdos models es feren servir a la Primera Guerra Mundial i més enllà fins la guerra civil espanyola i la Segona Guerra Mundial.

==========================

 

Huet military binoculars from the early 20th century are probably some of the most interesting to find, and generally quite reasonably priced. Their shape is quite different from the more modern ones, taking on a decidedly archaic air.

 

Above all, the rangefinder system incorporated in the infantry and cavalry models is very interesting. In fact, not all Huet binoculars have this special system. They can be clearly identified by 3 details: a selector on the right eyepiece, plates showing an infantry and cavalry soldier at the bottom, and the text I.C. (Infanterie & Cavalerie) before the serial number. They are also marked as "7x".

 

The rangefinder (which in this example seems to work quite well) was used as follows: with the selector wheel, a calcite crystal is moved in front of one of the eyes, so that the image seen is double. Then you take a look at how much one of the images of the upper part of the enemy has been separated from that of the other eye, and you consult the engravings for this purpose that are under the prismatics. If for example there is a whole head difference, the enemy soldier is about 200 m., and if there is half a body, about 700 m.

 

There is another model of similar prismatics very similar but with higher magnification ("8x") and without the calcite selector or measuring plates. It was the model for artillery and engineers.

 

Both were extensively used in WW1 and even in WW2.
