SU1024LDH2 SWIR Camera
May 2010
Sensors Unlimited - UTC Aerospace SystemsRequest Info
PRINCETON, N.J., May 4, 2010 — Sensors Unlimited, part of Goodrich ISR Systems, has released the SU1024LDH2, a high-speed, digital line-scan SWIR (short wavelength infrared) indium gallium arsenide camera. The second-generation 1024-pixel camera features an increased line rate of >91,900 lines/s, making it suitable for spectral-domain optical coherence tomography (SD-OCT) imaging applications. In the 1.05-µm wavelength band, the imager can capture detailed 3-D SD-OCT volumes of the retina, choroidal vasculature and nerve head, offering important detail beyond the depth capability of current 0.84-µm systems.

The compact camera housing features both metric and SAE mounting holes on multiple sides for easy integration into existing systems or for other positioning purposes. Measuring 76.2 × 76.2 × 61.0 mm, the cost-effective camera can be easily mounted to spectrometers. Optional adapters are also available for C-mount, F-mount or FD-mount lenses for use with machine vision applications.
Wavelength response range is from 0.8 to 1.7 µm, with a 25-µm pixel pitch and aperture heights of 25 or 500 µm. The camera features integrate-while-read snapshot acquisition, and the operator-selectable trigger modes include free run, single line per trigger, programmable exposure and gated burst.

Applications include high-speed absorption or emission spectroscopy for use in combustion research or for agricultural/food product inspection. These applications are based on detecting the moisture, lipids, proteins or other molecular vibration absorbance bands in the 800-to 1700-nm range. Other uses include high-speed inspection of silicon boules or wafers for photovoltaics, solar cell/panel inspection, integrated circuits, and many machine vision tasks for sorting and monitoring continuous processes.

A standard lens interface initially made for 16mm movie cameras and now used primarily on closed-circuit television cameras. It is a 1-in.-diameter, 32-thread-per-inch interface with a flange-to-image plane distance of 0.69 in.
A light-tight box that receives light from an object or scene and focuses it to form an image on a light-sensitive material or a detector. The camera generally contains a lens of variable aperture and a shutter of variable speed to precisely control the exposure. In an electronic imaging system, the camera does not use chemical means to store the image, but takes advantage of the sensitivity of various detectors to different bands of the electromagnetic spectrum. These sensors are transducers...
