3-CMOS Prism-Based RGB Color Line Scan Camera With Camera Link
The JAI LT-200CL is an industrial grade color line scan camera based on JAI's advanced prism technology. Featuring a light beam splitter prism and 3 x 2048 pixels custom-designed CMOS sensors, the LT 200CL captures the red, green and blue spectral bands in 3 separate channels simultaneously through the same optical path and with co-site sampling accuracy.
The high color accuracy provided with the LT200CL, makes it ideal for demanding vision applications such as fruit and vegetable sorting, 2D/3D print inspection, wood inspection and surface inspection of e.g. flat panels and paint coating.
The LT-200CL is capable of running at scan rates up to 30383 lines/second at 80 MHz data clock while maintaining image quality at a signal-to-noise ratio of 57 dB.
For flexible setting of scan rates and resolution the LT 200CL features various pixel readout modes like full readout, binning, sub-sampling and windowing readout. Using sub-sampling or windowing readout modes the camera is capable of running at scan rates up to 60766 lines/second at 1024 pixel resolution.
A number of built-in pre-processing functions are available including flat-field compensation, flat-shading compensation and color shading compensation.
Gain correction as well as the electronic shutter can be set individually for the red, blue and green channels providing even further flexibility in image optimization.
Other features of the LT-200CL include one-push automatic white balance, a noise reduction function and a test pattern generator that can be applied as a set-up and installation aid to check the performance of the camera.
The LT 200CL camera is equipped with a Camera Link interface providing 24bit (3 x 8 bit) or 30bit (3x10bit) outputs.
To maximize the cameras ability to withstand the rigors of industrial environments, all LT200CL cameras undergoes extensive shock (50G) and vibration testing (3G) to ensure reliable operation over very long operation periods.
A ridged housing design provides maximum surface area for heat dissipation resulting in excellent temperature management and optimal image quality.
JAI's prism-block technology uses a single optical plane and enables users to avoid the complex alignment and encoding issues related to off-axis viewing, variations in conveyor speeds, surface undulations, or objects that roll or move as they pass through the camera's field of view.
The dichroic coatings used on the prism provide steep spectral curves, which minimize the color "crosstalk" and thereby increase the color precision when compared to tri-linear or dual-line color solutions.
These hard dichroic coatings also don't suffer degradation, providing accurate color performance over a longer product lifespan.
