THE use of the rectifier photo-cell to amplify galvanometer deflections is now well known; but I have never seen any explicit mention of the fact that, with the customary set-up 1, the deflections ...

A NEW loop galvanometer made by the firm of Messrs. Carl Zeiss, of Jena, possesses several novel features. Although with its most insensitive arrangement it is capable of detecting a microampere ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

The galvanometer, first invented in 1802, was a means of detecting electric current. It consisted of a needle that was deflected by the magnetic field that electric current created; a stronger ...

Designed specifically for mirror apertures from 30mm to 50mm, the MPM30K galvanometer utilizes CTI's advanced highly stable optical position detector. Boasting 5 microradians per degree C stability ...

Microoptics Opens Door for New Applications Puchheim, Germany – September 11, 2014 – SCANLAB AG underscores its innovation leadership in laser positioning and deflection systems by setting new ...

A “newer” galvanometer, circa 1880. Without going into the haggling involved with my procuring the galvanometer in Figure 1, let's just say the antique vendor wasn't knowledgeable about telegraphers' ...
