PRODUCTION PROCESS:

STEP 1: PRODUCTION OF GLASS CAPILLARIES

Large glass tubes are heated and drawn into thin glass capillaries of the desired dimension. The smallest possible outer diameter is 0.30 mm and is equivalent to approximately five times the thickness of a human hair.

STEP 2: COATING PROCESS

The inside of the glass capillary is coated with a luminescent powder (zinc sulphide). Any colour is possible. The colour green is most often used, as it is the brightest colour perceived by the human eye.

STEP 3: TRITIUM FILLING

The glass capillaries are filled with tritium gas in a process developed by mb-microtec.

STEP 4: LASER CUTTING PROCESS

The glass capillaries filled with tritium gas are cut to the desired length and at the same time hermetically sealed by a highly automated laser melting machine.

STEP 5: QUALITY CONTROL

Each individual light source is subjected to a strict quality and leak test.

STEP 6: APPLICATIONS

Depending on the application, the light sources are installed in aluminium or polymer sleeves with sapphire glass or fitted directly onto dials. Our trigalight products are mainly used in the tactical, watch, security, automotive, aerospace and aeronautical industries.
