High-Voltage Optoisolators
To provide power electronics design engineers
with a high-voltage optoisolator for use in harsh
environments and explosion-proof applications,
TT electronics Optek Technology has developed
a series of UL- and VDE-rated models with 20-
kV isolation, ≤50-ns propagation delay and
2-Mb/s data transmission rates. The OPI1268S
series complies with ATEX and ICEex certifications for electrical equipment used in hazardous
areas, as well as with IP65 standards for environmental sealing. The high-speed optoisolators
are designed for high-voltage power isolation in
applications requiring sealing against dust and
liquids, as well as in electrical equipment in
potentially explosive atmospheres, such as
transportation systems, hybrid vehicles, medical
devices and industrial control/safety systems.

Ultrashort-Pulse Lasers
Trumpf Ltd.’s TruMicro series offers ultrashort-pulse lasers and high pulse-to-pulse stability.
The 3000, 5000 and 7500 models can reduce
the manufacturing cost of photovoltaic cells as
well as enhance their performance. The compact 3000 instruments, with wavelengths of
1064 and 532 nm, are suitable for P1, P2 and
P3 patterning. These diode-pumped solid-state
lasers achieve good processing results and can
be integrated easily into existing systems because of their advanced cooling design. Patterning of thin-film cells made from CuInGaSe presents a challenge for the laser process, as does
structuring of molybdenum. The company says
that picosecond lasers offer a better solution
than nanosecond ones for these applications.

OEM Spectrometers
Ibsen Photonics designed its Rock UV line of
industrial-grade robust OEM spectrometers for
the 200- to 400-nm-wavelength range. The
athermal instruments typically enable optical
throughput four times higher than traditional
spectrometers because of a near on-axis beam
geometry in the optical bench and the use of
proprietary fused-silica transmission gratings.
The devices are supplied in three standard
models, using either a low-cost CCD, a high-
sensitivity back-thinned CCD for low-light appli-
cations or a low-noise CMOS line array sensor
for applications requiring a high dynamic range
and a high signal-to-noise ratio. The OEM-
friendly design enables adaptation of the detec-
tor and electronics, allowing customers to reuse
existing electronics and software designs.

The Spectroline Bi-O-Vision series two-in-one
transilluminators manufactured by Spectronics
Corp. feature two workstations, producing both
312-nm UV and white light. The TD-1000R
model offers fixed-intensity, while the TVD-
1000R offers variable-intensity control of either
UV or white light. The units are continuously
adjustable from 100% down to 50%, enabling
life sciences researchers to select the exact UV
or white-light illumination needed to photodoc-
ument samples with a single piece of equip-
ment. The UV-B (312 nm) intensity can be var-
ied without preset stops, from 6000 to 3000
µ W/cm2, and the white light output can be ad-
justed from 2000 to 1000 fc (186 to 93 lx). This
flexibility in irradiance control ensures long
sample preparation time.
