1Series Overview
1.1 Description
Teledyne Lumenera USB3 Vision compliant cameras provide a quick and easy means of capturing
high quality images on any USB 3.0 equipped desktop, laptop, or embedded computer. Because
they are USB-based, there is no need for a frame grabber. Instead, a single cable provides full
command control and data transfer at speeds of up to 380 MB/s (Lt series).
Lt-Ux0x-xxxxx and Lt-Ux1x-xxxxx USB 3 cameras are powered via the USB 3 computer port
and may optionally be powered through the external interface header. Lt-Ux2x-xxxxx USB 3
cameras (XL) must be powered through the external interface header. The external interface
header also provides access for hardware input and output signals.
Some of the Lt Series feature highlights include:
•Compliant with third-party USB3 Vision application development software
•Color or monochrome Sony IMX series electronic global shutter CMOS sensors
•High-Speed USB 3.1 Gen 1 interface for fastest image delivery and simplified connectivity
•128 MB / 256 MB (XL models) low-latency RAM frame buffer
•Transfer Burst Mode supported
•Region of Interest (ROI) option to provide higher frame rates
•Selectable 8 or 12-bit pixel data
•Multiple data rates supported, each optimized for lowest noise performance
•Compact, robust form factor
•Locking industrial micro USB (power / data) and General Purpose I/O connectors for control of
peripherals and lighting synchronization
•P-Iris connector for support of precise iris lens control (available with LT-Ux0x-xxxxx series
camera models)
•The Lt-Ux0x-xxxxx series with 4 GPI/O, the options are: 1 optically isolated output, 1
optically isolated input, and 2 configurable I/O ports controls for synchronization (trigger and
strobe) of multiple cameras, peripherals, and lighting
•The Lt-Ux1x-xxxxx series which uses a smaller case, has a reduced I/O signal set on a locking
9-pin connector
•The Lt-Ux2x-xxxxx series boasts up to 31 MP, is designed to support operating temperatures
between 0oC–50oC and is suited for outdoor applications such as traffic monitoring.
•FCC Class B, CE Certified
