UTC Sensors Unlimited Linescan 1024-LDH2 InGaAs Camera, 1024 pixels at 91,911 lps
The UTC Sensors Unlimited SU1024LDH2 is a 2nd generation high-speed 1024-pixel linescan InGaAs camera that increases the A-line rate to 91,911 lines per second. This enables spectral-domain optical coherence tomography (SD-OCT) at 1.04 μm to capture detailed 3-D volumes of the retina, nerve head and choroid layer in a blink of the eye. For 1.31 μm SD-OCT, diodearray based OCT systems offer superior phase stability for Doppler or Polarization-Sensitive OCT. The LDH2 provides 12-bit digital capture into base-format Camera Link® interface cards, while providing maximum dynamic range up over 2300:1 for high line rates. Two pixel apertures are available: 500-μm tall pixels for easy alignment in SD-OCT systems, or 25-μm square pixels for ultra-fast machine vision or dual-camera PS-OCT.
Features:
- 91,911 lps for 1024 pixels at 12 bits
- Integrate-while-read snapshot acquisition
- Wavelength response over 0.8 μm to 1.7 μm with flat QE for 1.05 and 1.31 μm OCT
- 25 μm pixel pitch with aperture heights of 25 μm (defined by on-chip mask) or 500 μm
- 12-bit base Camera Link® compatible output and control
- High quantum efficiency and dynamic range
- Operating temperature range of -10 to +50°C
- Mounts easily to spectrometers due to 5.7 mm image plane depth and O-ring light seal
- Mounts easily to optics benches or MV systems with tripod, front or side fastener hole patterns
- Optional adapters for F-mount or C-mount, lenses (C-mount lenses may not fully illuminate the full width of the 25.6 mm wide arrays)
Applications:
- Spectral-Domain Optical Coherence Tomography (OCT)
- Ultra-fast absorption or emission spectroscopy for combustion research, moisture, lipids, proteins or other molecular vibration bands in the 0.8 to 1.7 μm range
- Machine vision for ultra-high speed inspection, materials classification, sorting and/ or monitoring of continuous processes, for example for food or agricultural product sorting
