3-CMOS Prism-Based RGB Line Scan Camera

The JAI LT-400CL is the first member of JAI's new family of prism-based color line scan cameras built around a series of custom-designed CMOS linear sensors. The LT 400CL features three prism-mounted sensors, each with 4096 (4K) pixels. The high performance CMOS sensors output 4K line resolution at 16,180 lines per second, while maintaining image quality at a signal-to-noise ratio of 55 dB or higher.

The single optical plane of the prism-based design of the LT400CL eliminates off-angle viewing problems, complicated alignments, and other issues that often plague tri-linear camera alternatives.

Typical of JAI's multi-imager color cameras, the dichroic coatings on the prism boundaries of the LT-400CL 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 the degradation of the soft polymer dye filters on tri-linear and dual-line sensors, providing accurate color performance over a longer product lifespan.

The sub-pixel sensor alignment delivers precise color values for each pixel, making the LT-400CL camera ideal for web-based inspections where accurate color information is required.
