Some applications require line scan cameras, where the continuously moving “product” is passed below a sensor that is wide in one dimension and narrow in the other, and fast enough to keep up with the pace of motion. See our piece on area scan vs. line scan cameras for an overview.
Teledyne DALSA’s new Linea HS 9k BSI Near ultraviolet (NUV) / visible camera is such a line scan camera, at 9216 x 192 resolution, and speeds to 400 kHz (mono mode) and 200 kHz (HDR mode).
Visible spectrum as well as Near Ultraviolet (NUV)
The camera uses Teledyne DALSA’s own charge-domain CMOS TDI sensor with a 5×5 μm pixel size. In addition to the visible spectrum 400 nm – 700 nm, the sensor delivers good quantum efficiency to 300 nm, qualifying Near Ultraviolet (NUV) applications in the blue range as well.
Backside illumination enhances performance
Backside illumination (BSI) improves quantum efficiency (QE) in both the UV and visible wavelengths, boosting the signal-to-noise ratio.
Interface
The Linea HS 9k BSI camera uses the CLHS (Camera Link High Speed) data interface to provide a single-cable solution for data, power, and strobe. And Active optical cable (AOC) connectors support distances up to 100m. That avoids the need for a repeater while achieving data reliability and cost control. See an overview of the Camera Link standards. Or see all of 1stVision’s Camera Link HS cameras.
Applications
Delivering high speed high sensitivity images in low light conditions, the Linea 9k HS is used in applications such as:
- PCB inspection
- Wafer inspection
- Digital pathology
- Gene sequencing
- FPD inspection
