UV Light Measurement
Dymax Corp. has released the
Accu-Cal 150, a radiometer offering repeatable, NIST-traceable
measurement of UV light for validating and monitoring a light-curing process. The instrument
can measure UV light up to 10
W/cm2 emitted from stationary
light-curing floodlamps or lamps
used in conveyor processes. It can
be used to determine intensity
(measured in m W/cm2) or total
energy as derived from intensity
and exposure time (measured in
mJ/cm2). The device also can be
used to measure the light transmission rates of various wavelengths through substrates that
absorb UV and/or visible light.
Spectral sensitivity is 320 to 390
nm, and typical accuracy is ±5%.
Using radiometers in UV light-curing application processes ensures that
any changes to the properties of curing energy are identified.
AFL’s FuseConnect MPO fusion-spliced, field-terminated connectors feature just six components. With a factory prepolished ferrule, their field-ter-mination process eliminates polishing, adhesives and crimping in the field.
Compliant with Fiber Optic Connector Intermateability Standard (FOCIS),
Type MPO, FOCIS- 5 and TIA-604-5-C, the connectors perform as an
equivalent to the standard factory-terminated MPO/MTP assemblies. They
were designed to use either ribbon or loose tube cable, minimizing the
complexity involved in the termination of a multifiber connection and enabling reliable and repeatable termination in field applications. Features
include field MPO polarity customization, 3-mm round and optical fiber,
and ribbon flat boots in each pack. Applications include connectorization
in radio-frequency overlay fiber-to-the-premises networks.
Laser Speckle Reducers
Edmund Optics has introduced laser speckle
reducers suitable for beam homogenization,
3-D scanning, metrology, microscopy and interferometry applications. They remove local
interferences and reduce speckle noise in
laser systems by dynamically diffusing the
laser beam. Diffusing angles of 1°, 10° and
20° are offered. Compact, for ease of integration, they feature integrated drive electronics and vibrationless speckle reduction.
They use four electro-optic polymers that selectively move each laser speckle reducer’s
central diffuser along the X- and Y-axes to
form a circular pattern of motion. For maximum speckle reduction,
the user positions the instrument perpendicular to the laser beam and
focuses a collimated laser source with a beam diameter equivalent to the
reducer’s clear aperture.
Flir Advanced Thermal Solutions has
developed a multispectral near-infrared
camera for high-end science and R&D
applications. The fully integrated
SC7100 covers the spectral range from
0.4 to 1.7 µm and combines high-performance thermal imaging and noncontact temperature measurement. The
