Camera isn't fooled by blue moves
The CL-T7 is Dalsa's latest colour linescan camera delivering significantly more sensitivity than previous models.
The CL-T7 is Dalsa's latest colour linescan camera delivering significantly more sensitivity than previous models Using tri-TDI (time domain integration) technology its sensitivity out-performs competitive tri-linear and three-chip products by a factor of at least 20x with better signal to noise ratio

IEEE-1394 digital camera technology without a PC
The Sony Digital Imaging Station (DFWS 77) enables non PC users to take advantage of high quality IEEE-1394 digital camera technology with its sharp low noise advantage
The CL-T7 replaces the existing CL-T5 using a more advanced and more robust tri-TDI sensor.
TDI works by combining multiple linescan stages to integrate over a longer period.
The CL-T7 delivers 24bit RGB pixels at 25MHz from its 2048 x 14um pixels which in real terms mean a maximum line rate of 10.7kHz.
Using TDI technology in colour applications enables a hardware solution to the traditional problem of low CCD sensitivity to blue light.
The camera has more blue TDI stages which boosts the blue, thus removing the need to increase blue gain.
White balance is done by both TDI stage selection, along with separate R, G and B gain controls.
Markets that will find the CL-T7 most applicable would include: 100% print inspection (and colour document scanning); ceramic tile inspection; and printed circuit board inspection. Request a free brochure from Firstsight Vision ...
