Laser position and
power sensors
A line of 18 × 18 mm laser positioning sensors acquire and process precise
data on the power and position of laser
beams. The sensors are designed for
powers from 100 µ W to 50 W and rely
on the company’s thermoelectric technology, eliminating saturation problems
and wavelength-dependent sensitivity.

Bandpass filters
Enhanced-performance dichroic fil-
ters for laser applications, available on
www.ealingcatalog.com, feature an ion
beam-sputtered coating that maintains
stability with changes in heat, humidity,
and pressure. The coating delivers very
high transmission for long-pass wave-
lengths and extremely high reflection
of the shorter wavelengths.

Large-aperture isolators
Model 815 large-aperture, free-space
optical isolators have use with 1064
nm Nd:YAG lasers. They preferentially
transmit light along a single direction,
shielding upstream optics from back
reflections. Features include high power
capability (500 W/cm2 for continuous-wave lasers and 150 MW/cm2 for
pulsed lasers), an operating range of
1020–1100 nm, an 8 mm aperture, isolation > 30 dB, and transmission >92%.

Picosecond pulsed LED
The EPLED 310 picosecond pulsed LED
is pre-adjusted for an optimum pulse
width of <800 ps and optimized for
time-correlated single-photon counting (TCSPC). Typical instrumentation
applications include fluorescence lifetime spectrometers and fluorescence
lifetime multiwell plate readers.
