| The Spectroline®
ultraviolet quartz pencil lamps cannot be beat for their small size,
light weight and long life. They’re ideal for the widest range of
applications. In fact, these features make Spectroline pencil lamps
the most useful and versatile UV light sources of their type.
Spectroline quartz pencil lamps are small, low-pressure,
mercury-vapor discharge lamps made of double-bore material with
both electrodes at one end. They are very stable lamps, when used
properly, and maintain a high output of ultraviolet radiation over
thousands of hours. This long life and stability is especially important
to instrument manufacturers incorporating these lamps into their
equipment.
Spectroline pencil lamps have a spectral emission
characteristic of a low-pressure mercury discharge consisting of
many well-separated lines in the ultraviolet, visible and infrared
parts of the spectrum (see Figures 1 and 2). They are widely used
as spectral calibration sources in spectroscopy, chromatography
and photometry, and a multitude of other laboratory and industrial
applications.

11SC-1 Short
Wave UV Lamp
|
Average
Intensity —
4,500 µW/cm2 of 254nm (2537 A°U, 254mµ) radiation at
1" (2.54cm).
Housing
— The quartz tube is bonded inside a phenolic
handle with Viton™ and a special insulating resin. A 24"
(61cm) ozone-resistant cord set with plug is provided for attachment
to the Spectroline SCT-1A power supply.
Dimensions
— The lighted length of the tube is 21⁄8"
(5.30cm), 1⁄4" (0.65cm) OD. The handle is 3⁄8"
(0.95cm) OD and 5⁄16" (0.79cm) ID. The total length of
the lamp housing is approximately 5" (12.7cm).
Operation
—
The lamp plugs into the Spectroline SCT-1A power supply.
Net

36-380 Long Wave UV Lamp
The Spectroline 36-380 pencil lamp is one of the
smallest sources available of filtered, long wave ultraviolet (Black
Light) radiation. It is basically the 11SC-1 lamp coated with conversion
phosphors that absorb the 254nm line and convert this energy into
a band peaking at 365nm. The lamp in encased in a tubular glass filter
that absorbs visible light while transmitting maximum ultraviolet
intensity. The 36-380 lamp is ideal for fluorescent penetrant analysis
and boroscopic inspection in ordinarily inaccessible locations.
|
Average
Intensity —
1,000 µW/cm2 of 365nm (3650 A°U, 365mµ) radiation
at 1" (2.54cm).
Housing
— Same as 11SC-1.
Dimensions
— The lighted length of the tube is 21⁄8"
(5.30cm), 3⁄8" (0.95cm) OD. The total length of
the lamp housing is approximately 51⁄4" (13.34cm).
Operation
— Same
as 11SC-1.
Net
Weight —

SCT-1A Power Supply
The separately housed Spectroline SCT-1A
power supply provides correct electrical characteristics for efficient
operation of the 11SC-1, 11SC-2 and 36-380 lamps. The SCT-1A provides
1,200 volts open circuit for starting the lamps — considerably above
the 800 volts needed. The 11SC-1 and 36-380 will operate at 295
volts and 18mA; the 11SC-2 will operate at 205 volts and 18.5mA. |
 |
The dimensions of the SCT-1A are 41⁄2L
x 4W x 31⁄8” H (11.4L
x 10.2W x 7.9cmH). The net weight is 5 lbs. (2.3kg). The metal
housing is provided with an on/off switch, rubber feet, a 71⁄2
ft.
(2.3m) primary cord and a 3 ft. (0.9m) secondary cord. It operates
on 115V AC/60Hz. A 230V AC/50Hz version is also available,
model SCT-1A/F. |
