TECHNICAL INFORMATION
Spectral Distribution
Deuterium lamps emit high intensity light in the UV range at wavelengths
shorter than 400 nm. Light intensity on the short wavelength side is deter-
mined by the window material used.

UV GLASS
Light Distribution
The non-projecting type uses the side of the cylindrical glass bulb as the
emission window, whilst the projecting type uses a plane glass attached
to a projection on the bulb.
The projecting type has a uniformed transmittance due to the plane glass.
Since the window is located far from the discharge position, the amount
of dirt produced by spattering from the electrodes is reduced resulting in
low deterioration of light output. The non-projecting type requires less
space and has a wider directivity since there is no projection, enabling
effective use of emitted light. The long-nose projecting type uses an
MgF2 window and is suitable for vacuum ultraviolet applications. This
type is used with the tip of the nose inserted into the vacuum equipment.

Window Material
The following 4 types of window material are available for deuterium lamps.
(1) UV glass
(2) Synthetic silica
(3) MgF2
Figure 2 shows the transmittance of various window materials.
UV light at wavelengths shorter than 190 nm attenuates greatly due to its
absorption by oxygen. To obtain the fullest performance in window trans-
mittance, it is recommended that the inside of the equipment be filled with
nitrogen or vacuum-evacuated to eliminate this absorption effect.

GUV glass
UV glass has a higher ultraviolet transmittance than normal optical glass
(borosilicate glass). It has the longest cut off wavelength of 185 nm among
the four types. However the generation of ozone is lower than other wind-
ow material types, it is not necessary to have special anti-ozone treat-
ments.
GSynthetic silica
Synthetic silica is obtained by fusing a silica crystal that is artificially
grown. Although its cut off wavelength is 160 nm, it contains less impuri-
ties than fused silica, and transmittance at 200 nm has been improved by
approx. 50 %.
GMgF2
MgF2 is a crystallized form of alkali metal halide that has an excellent
ultraviolet transmittance, a low deliquescence and is used as window
material for vacuum ultraviolet applications. Its cut off wavelength is 115
nm.

Arc Distribution
Arc intensity is determined by the aperture (light exit) size. Figure 5
shows typical spectral distributions for lamps with different aperture sizes.
At the same input current and voltage, lamps with an aperture of 0.5 mm
diameter (high brightness type) provide 1.6 times higher brightness than
lamps with an aperture of 1.0 mm diameter (standard type). The half
width of spectral distribution also becomes narrower with a reduced aper-
ture size. When higher intensity is required or the object to be irradiated
is very small, the high brightness type is recommended.
