Many lasers used today produce emissions in the non-visible, infrared portion of the electromagnetic spectrum. Consequently, it is useful to have devices that can detect the laser emissions permitting proper alignment and evaluation. For many applications, it is extremely important to know the cross-sectional profile of a laser beam. In this way, the power, energy density, modal structure and divergence of the laser can be determined. Infrared imagers offer an ideal method for analyzing laser beam profiles from 800 nm to 20 microns.
ElectroViewer 7215 is a high performance, hand-held
infrared viewer designed to meet the requirements
for near IR laser beam finding and alignment.
The ElectroViewer delivers a remarkably bright
image, features and standard C-mount lens and
accessories that make it the perfect tool for
in-the-lab and in-the-field.
8640 InGaAs Camera
The MicronViewer 8640 SWIR Camera is an ultra compact InGaAs-based SWIR camera based on a new generation of Sofradir InGaAs detectors. The 8640 includes a 640x512 InGaAs array having excellent sensitivity and resolution in a compact housing. The camera includes desktop software resulting in a plug-and-play solution. In addition, the camera is available as a module with simplified interfaces for easy integration into SWIR-based systems that optimally drive the detector and perform image processing functions. The MicronViewer 8640 is well adapted to a large range of scientific applications such as laser profiling, spectroscopy, hyperspectral imaging and machine vision.
Infrared Cameras - MicronViewers
7290 and 7292M
MicronViewer is a near infrared video camera
with spectral response from 0.4 to 1.9 µm (2.2
µm optional). Simple controls and compact size
make the 7290 easy to use. Used by optical telecom
component developers, the camera’s combination
of high sensitivity, high resolution, compact
size and low price have made it the world’s best
selling short-wave infrared camera.
The MicronViewer 7292M is a high performance near infrared camera designed for the detection of near infrared radiation in the spectral range from 0.4 to 1.9 µm (2.2 µm optional). It is extremely useful for applications requiring high performance, flexibility and maximum stability. The camera features a separate camera head and control unit facilitating adjustments while the camera is in use. Front panel controls allow for a variety of different optimization methods. Controls for auto/manual gain and black level selection permit the maximum possible contrast enhancement for the most demanding of low contrast imaging applications.
Uncooled Infrared Camera - PV640LW
Incorporating an uncooled 640x480 microbolometer detector array, the PV640LW Uncooled Infrared Camera delivers high resolution infrared images in the long-wave (8-14µm) spectral range. The camera is available with a variety of different infrared objective lenses and with either Gigabit Ethernet or Camera Link digital video output. Because of the PV640's short thermal time constant, the camera produces superior thermal images even while imaging fast moving objects.
Lenses for C-Mount Cameras
offers a wide range of lenses designed for 1" C-mount
cameras and viewers. In general, the lenses feature
manual focus and an integrated adjustable iris
diaphragm. These lenses also feature broadband
lens coatings making them ideal low cost solutions
for imaging in the near-infrared spectral range
with reduced flare and ghosting. A C-mount Extension
Tube kit is also available for those applications
requiring close focus and higher magnification.
Also included are two quartz objective lenses
that are suitable for imaging from UV through
Near-IR range. These objective lenses perform
well for monochromatic imaging in the noted spectral
range. It is important to note that they are
not chromatically corrected for the entire spectral
Filters for Infrared Cameras
optical filters are perfect for many imaging
applications that benefit from blocking out-of-band
electromagnetic radiation while passing other
wavelength regions. These filters are normally
positioned in front of a camera’s objective lens
or between the camera’s lens and imaging sensor.
When positioned as such, the filters attenuate
(by reflection and absorption) out-of-band transmission
and transmit the desired spectral region. Constructed
of hard, durable coatings on optical-quality
substrates, these filters will withstand normal
cleaning and handling associated with any high
quality optical component. Custom filter wavelength
characteristics and sizes are available upon
