The new XCL-S Series cameras incorporate a 1/1-type EXview HAD CCD II™ sensor which provides extremely high sensitivity. In addition to inheriting many convenient functions from Sony’s XCL Series, such as Bulk Trigger and Sequential Trigger modes, these new cameras also incorporate some unique features including Shading Correction, Defect Correction, and Temperature Readout.
These new advanced features and benefits make XCL-S Series cameras ideal when the highest inspection quality is demanded for display panels, semiconductors, solar panels, PCBs (Printed Circuit Boards), and pharmaceutical applications.
KEY FEATURES
Near-infrared Sensitivity
Utilizing Sony’s EXview HAD CCD II technology enables XCL-S Series cameras to capture clear images in NIR (near-infrared) wavelengths. When used with an infrared
strobe, each camera produces outstanding picture quality especially in low light and NIR inspection applications.
High Frame Rate Image Transfer
XCL-S Series cameras feature a high readout rate of uncompressed images for smooth and clear results. The XCL-S600 and XCL-S600C achieve 27 frames per second (fps), and the XCL-S900 and XCL-S900C achieve 18 fps when fourchannel
output is selected. This enables these cameras to capture fast-moving objects without sacrificing image quality.
Shading Correction
With embedded shading correction, XCL-S Series cameras minimize the uneven image intensity often caused by lighting and/or the lens. Their internal hardware processing reduces the need for external image correction that is normally
performed via a frame grabber board and PC. This handy function reduces the processing load of the PC, and simplifies the processing task. In addition, these cameras are equipped with three optional lighting settings to capture clear images
in varying lighting conditions.
Defect Correction
XCL-S Series cameras can automatically minimize defective pixels (e.g., white and black dots) within the entire imaging area directly inside the camera. This feature helps simplify image processing.
Temperature Readout
Each camera comes with an internal temperature sensor. The host device can receive temperature information by issuing a command. This eliminates the need for a separate sensor, and simplifies system configuration.
Sensitivity Control
The XCL-S Series is equipped with a saturation signal control function to allow the amount of saturation signal charge on the CCD to be increased or decreased via software commands. For example when capturing dark objects, the user can increase the amount of saturation signal charge – this elevates the camera’s sensitivity to improve the picture quality instead of using a long exposure time*. On the other
hand, by decreasing the amount of saturation signal charge, the level of smear can be reduced or improved.
* If the saturation signal charge amount exceeds the maximum that can be transferred into the vertical and horizontal registers, a transfer error will occur (e.g., smear).
Memory Channel (Userset)
In addition to factory default settings, up to 16 camera parameters – including brightness, gamma, shutter, gain, and trigger mode – can be preset to suit each
particular scene.
Bulk Trigger Mode & Sequential Trigger Mode
These new XCL-S Series cameras feature advanced Bulk Trigger and Sequential Trigger modes in addition to a conventional trigger mode. Each camera supports 16
memory channels that can store up to 16 different camera setups (e.g., exposure, and gain).
Bulk Trigger mode allows these cameras to capture up to 16 images in rapid succession using a single software or hardware trigger.
Sequential Trigger mode allows each camera to capture a single image using successive setups stored in the memory channels with each software or hardware trigger.
Look-up Table (LUT)
Each XCL-S Series camera supports a look-up table which transforms the input luminance signal into the required digital output. It supports factory presets – Linear, Negative, Binarization, and Linear Interpolation – as well as a Userdefined
LUT (input: 12 bits, output: 12 bits).
Trigger Noise Filtering
With a trigger line filter, these cameras can specify a valid pulse width for the trigger. This helps avoid unexpected image capture caused, for example, by triggers from insignificant noise.
Pulse Train Generator
XCL-S Series cameras are capable of outputting any rectangular wave from one of the general-purpose outputs. This pulse train can be programmed for frequencies from
0.5 Hz up to 100 KHz in 1 μs steps to control external devices such as LED lights, simplifying overall system configuration."
