Plastic Acylinder Lenses
Edmund Optics has introduced its TechSpec
plastic hybrid acylinder lenses. Similar to
aspheric and cylinder lenses, they provide dif-fraction-limited focusing performance in only
one dimension. Designed at 587.6 nm, they are
suitable for use in the visible wavelengths. The
lenses reduce spherical aberration along the
focusing axis for creating precise thin-line profiles with broadband sources. The hybrid lens
design offers negative optical dispersion and
good color correction. The lenses feature a high
numerical aperture, enabling their use with divergent light sources such as laser diode bars
and LEDs. They are available with a 25-mm diameter in focal lengths of 20, 25, 30, 40 and
50 mm for ease of integration into a variety of
applications. They are offered either uncoated
or with a visible coating.
For time-resolved imaging applications, Andor
Technology plc has launched an addition to its
iStar range of scientific-grade intensified CCDs.
The iStar 312T imaging platform operates at ac-
quisition rates of > 15 fps, rendering it suited to
combustion analysis and plasma studies. Crop
mode and fast kinetic mode enable acquisition
rates in excess of 5500 spectra per second,
continuous, and 55,500 Hz, burst, respectively.
Features include a − 40 °C thermoelectric cool-
ing interface, low-noise electronics and high-
quantum-efficiency photocathodes for high sen-
sitivity, ultraprecise timing control via low-jitter
electronics and a comprehensive software con-
trol interface, and gating of better than 2 ns.
The integrated digital delay generator delivers
ultralow insertion delay and timing accuracy
down to a few tens of picoseconds, allowing
synchronization of complex experiments through
a range of input/output triggering options.

Keyence Corp. of America’s TM-3000 2-D opti-
cal micrometer introduces technological ad-
vancements to 100% automated high-speed,
in-line or off-line measurement and inspection
applications. It combines the functionality of a
laser scan micrometer, a machine vision system
and an optical comparator. Available in three
sensor head sizes, it enables use of two trans-
mitter-receiver pairs simultaneously. The mi-
crometer employs a dual telecentric lens to cre-
ate uniform collimated light with a green LED.
A 2-D CMOS array then detects the light-to-dark
transitions on the array to measure the dimen-
sions. High speed and high precision are a re-
sult of subpixel processing only in the areas or
points designated for measurement. Because the
system works in two dimensions, it can measure
up to 16 points within the measurement area.
