超紧凑型Bobcat-640-CL系列可满足在SWIR范围需要高灵敏度机器视觉系统设计人员的要求，以用于专门的质量检测和高温过程控制。

Bobcat-640-CL系列可在640 x 512分辨率下实现100 Hz的帧速率，是高速成像的完美之选。这款摄像机配备工业标准CameraLink接口，能够以全帧速率进行数据传输。在窗口模式下，其帧速率还可提高。

Bobcat-640-CL系列可作为整套摄像机产品提供，并配备内置图像处理功能和热电稳定功能，以获得低暗电流和优化的噪音性能，从而最终实现卓越的图像质量。 VisNIR选装方案可将波长范围扩展到可见光领域，以在微光应用中获得最佳灵敏度。

20 μm像素尺寸使得Bobcat-640-CL系列可兼容更多的C口镜头以及其他低成本镜头。
