Gamma Detection and Identification
System
Rock West Solutions (RWS) (Santa Barbara,
CA) launched a new product this month called
APEX, a high-performance gamma detection and
identification system comprised of a handheld
detector and accompanying analysis software.
This device has 5-10x higher resolution than most
traditional handheld detectors due to the incorporation of commercial-grade CZT
crystals. APEX captures gamma counts, assembles a full energy spectrum, and interfaces
with a Windows laptop running the APEX analysis software. The APEX GUI displays
the collected spectrum with user-friendly isotope identification tools. RWS uses
commercial-grade CZT crystals with cutting-edge electronics designed to provide an
economical, high-performance gamma detection and spectroscopy solution. Gamma
resolution as low as 1.25% at 662 keV is achievable.

APDs and SPADs
X-FAB Silicon Foundries (Tessenderlo, Belgium) has just
introduced its latest generation of avalanche photodiode
(APD) and single-photon avalanche diode (SPAD) devices.
Leveraging its 180 nm XH018 high-voltage process, X-FAB's
new APDs and SPADs benefit from architectural modifications,
boosting performance in relation to the photon
detection probability (PDP). There is a 42% PDP figure for
incident light at 405 nm, while further up the spectrum in
the near-infrared (NIR) frequencies the improvement is as much as 150%, with a 5%
PDP being demonstrated at 850 nm. An afterpulsing probability of 0.9% has been
achieved which represents a 70% reduction compared to the first-generation devices.
The dark count rate (DCR) is only 13 counts/s/µm².

Multi-Sensor Vision System
The L.S. Starrett Company (Athol, MA) has
enhanced its AVR300 Multi-Sensor Vision System
with a 0.14 magnification lens featuring the largest
field of view to date on the AVR Series at 2.36 " x
1.90 " (60 mm x 48 mm). Due to " superimage " technology,
which allows multiple images to be stitched
together to form one larger image, together with
the system's touch probe technology, the AVR-FOV 0.14X can accurately inspect a
wide range of features on large or complex parts, as well as on multiple small parts.
The AVR-FOV 0.14X automated part programs deliver accurate results to the micron
level in a matter of seconds with " Go/ No-Go " tolerance zones, and data are provided
in one easy-to-interpret report. The AVR-FOV 0.14X has an X-Y-Z travel of 12 " ¥ 8 " ¥
8 " (300 mm ¥ 200 mm ¥ 200 mm).

UV-Enhanced Detector
Opto Diode Corporation (Camarillo, CA) an -
nounced an ultraviolet-enhanced detector featuring a
5.5 mm diameter active area. The UVG20S photodiode
is ideal for UV detection between 190 nm to 400 nm
spectral wavelengths with a full spectrum of 190 nm out
to 1000 nm. The device features stable responsivity over
wide temperature ranges and features 100% internal quantum efficiency from 200 to
400 nm. The photodetector is packaged with a UV quartz window that is epoxy-bonded
in place. Under test conditions at 254 nm, the UVG20S detector's responsivity
ranges from 0.105 A/W (minimum) to 0.115 A/W (typical). Shunt resistance is 100
MOhms (typical) and reverse breakdown voltage is 50 volts (typical). At 0V bias,
capacitance is 1.5 nF (typical) and response time is 4 microseconds (typical).

QFN packages. The SG25-QFN-2017
socket is designed for a 4 mm ¥ 4 mm
package size and operates at bandwidths
up to 52 GHz with less than 1dB of insertion
loss (GSSG configuration). The contact
resistance is typically 20 milliohms
per pin. Network analyzer reflection
measurements for the G-S-S-G case were
taken with all except the pins under consideration
terminated into 50 Ohms. The
socket utilizes clamshell lid with an integrated
spring-loaded compression plate
that applies required force for connecting
ICs to the system PCB. The socket
also incorporates an open top with 150degree
view for the optical chip.
