Marking
General notes
1. Engraving
In addition to the most commonly used world languages, in
DIN1451-3 close spacing, other typefaces are available as
Scandinavian, Slavic, Greek, Russian and Polish. Red, blue and
black lenses are filled with white colour. Other colour lenses
arefilled in black. Standard height of letters is 3
mm. If the height
is not specified, we will supply 3
mm engraved letters.
2. Hot stamping
For larger series it is worth considering markings by means of hot
stamping. We will pleased to advise you. For letters and figures,
typefaces with 2.5
mm, 3 mm and 4 mm are available.
3. Film inserts
Instead of using engraving the lenses can be fitted with transpa-
rent film inserts, as an alternative. For this purpose, though, it
isadvisible to use lenses without ripped pattern. In the case of
use of a smoke-black lens the fitted film becomes readable only
ifthe lamp is on. The film (F) is inserted in the cap. To ensure
evenillumination a diffusor (D) is recommended, which is inserted
beneath the film. If, on the other hand, the diffusor is inserted
above the film, the lettering only becomes legible when the lamp
is alight. To hold the film and diffusor in position, the use of a
holder (N) is advised. The film thickness is 0.2 mm.
