; VLWIR Filters
Deposition Sciences Inc.’s line of very long wavelength infrared (VLWIR) filters provides high transmittance from the 12- to beyond the 22-µm-wavelength region. Fabricated using a proprietary and
precise physical vapor deposition process, the coatings pass all environmental tests and can be repeatedly cycled between ambient and cryogenic temperatures without degradation. They are available with antireflection coatings in narrow- and wide-bandpass, and in long- and short-wave-pass
types. They can be applied to a variety of substrates, including germanium, zinc selenide, silicon and
indium antimonide. Edge placement, transmission blocking ranges and levels, and operating temperatures and angles can be customized per specifications. Applications include remote sensing, chemical analysis, astrophysics/astronomy and horizon sensors.

6-Megapixel Cameras ;
Point Grey Research Inc. has added
6-megapixel models to its Grasshopper Express Fire Wire-b digital
camera series. The GX-FW-60S6
uses the Sony ICX694 to deliver
high resolution and sensitivity,
and the ICX694 applies EXview
HAD technology to high-resolution multitap image sensors. Known for high quantum efficiency, reduced smear and increased NIR sensitivity, ICX694 is a 1-in. CCD that produces
2736 ; 2192-pixel images at 11 fps. The cameras have a tripod mounting bracket and on-board temperature and power sensors. The FlyCapture software development kit library
provides a common control interface for all of the company’s cameras under Windows
and Linux. The 800-Mb/s bandwidth delivers low-latency, deterministic image transfer
without CPU loading. Applications include machine vision and bioscience. The GX-FW-
60S6M-C (monochrome) and GX-FW-60S6C-C (color) models offer high sensitivity, short
exposure times that eliminate motion blur, and postcapture gain.

White Chip-on-Board LED
Excelitas Technologies’ ACULED chip-
on-board white LED delivers a combina-
tion of correlated color temperature
(CCT), high color rendering index (CRI),
and high R9 value and output needed
for applications such as surgical oper-
ating room and examination lights, and
dental operatory lighting. It contains
four separately addressable chips to provide tunable CCTs from 3500 to 5500 K. CRIs
greater than 95 and R9 values above 90 are achievable. Benefits of the new LED include
good heat transfer from the chips to the substrate and heat sink, and a compact design
with chips that are closely spaced, enabling improved color mixing and compact optics.
The company offers a standard four-chip chip-on-board package (Model R3C6) that is
supplied with warm-white, cool-white, red and cyan LED dice.
Continuous-Wave Integrated Lasers
Solid-State Lasers ;
InnoLas Laser GmbH’s picolo AOT series electro-optical Q-switched lasers are compact high-repetition-rate, short-pulse solid-state devices operating with
high energy in the UV, visible and near-infrared.
Proprietary high-speed switching technology allows
them to deliver kilohertz pulses below 1-ns duration
that are synchronizable to external events with sub-nanosecond accuracy. The lasers comprise master
oscillator power amplifier units and operate with a
pulse rate from 0 to 100 kHz, pulse energy >100 µJ
and peak power >100 k W. Used in R&D applications,
their short, intense pulses provide many advantages. In precision processing and marking, the
short interaction time reduces workpiece heating effects and improves quality. In ranging applications
and in excite-and-probe studies, short pulses increase temporal resolution. In nonlinear harmonic
and parametric processes, the high intensity of the
short pulses leads to high conversion efficiency.

Blue Laser Diode ;
The PL TB450 blue laser
diode from Osram Opto
mounted in a compact
TO-56 package and features optical power of
1.4 W, making it suitable
for professional projectors with a luminous flux
of more than 1000 lm for
use in offices, conference rooms and home
cinemas. Built on an
InGaN substrate, it is
suited for medical applications and for laser
systems for stage and decoration illumination. At
450 nm, the diode produces the blue laser light desired and, with 1.4 W at room temperature and a
current of 1.2 A, the required high optical power. Efficiency is 27%, so the temperature of the laser will
rise only slightly when in use, giving it a service life
of up to 10,000 h at 40 °C in continuous operation.
