12.3 Signal conditioning
The analog output of the sensor is conditioned by Correlated Double Sampling
(CDS) for optimum S/N ratio. Dark level drift is compensated by an “auto zero”
amplifier circuit and fed into a video ADC with 10 or 12 (1 tap) or 14 Bit (2 tap)
Bit resolution (type dependant). The data are fed into an internal 16 MB
Memory. The camera is controlled by an FPGA and the data packages are sent
via an Ethernet controller to the PC.
12.4 Optical and mechanical issues
12.5 svs424, 204 and svs285 only
Camera size: 50mm x 55mm x 80mm (without connectors and lens)
Weight: Approx. 300 gram
Front plate with M 42 x 1 threads and C-Mount adapter for 4021.
all others with C-Mount
Distance from Chip surface to frontplate: 11,65mm
Please note: The C-Mount adapter of svs4021 is intended for easy
setup. However it might cause dark edges due to a loss of light in the
corners. This is known and not a fault of the camera. We recommend
the use of solutions from Schneider, SILL or LINOS (Rodenstock) who
offer interfaces to M 42 thread. Sometime C-Mounts work with focal
length longer than 50mm. Do not use lenses which are intended for
CCDs smaller than 1’’!
svs285
Camera size: 51mm x 55mm x 65mm (without connectors and lens)
Weight: Approx. 250 gram
