Production
Individual glass vessels are manufactured in various shapes depending on customer requirements. Basically, almost any sealable glass vessel can be transformed into a trigalight. Next, the inside surface of the trigalight is coated with luminous substance. To achieve the highest quality possible, this must be done entirely by hand. Then, the vessel is filled with tritium gas (an isotope of hydrogen) and sealed.

The manufacture of small, cylindrical trigalight used in watches, sights and other applications is fundamentally as described on the previous page. The only difference being that long capillaries of the desired diameter are first coated, filled with tritium gas, sealed and only then “cut” to the desired length by means of a laser, specifically developed for this purpose. |
