22B-A012N114

22B-A012N114镜头在摄像机成本构成中的比例为20%左右，是摄像机的重要组成部分。镜头相当于人眼的晶状体，如果没有晶状体，人眼看不到任何物体；如果没有镜头，那么摄像头所输出的图像就是白茫茫的一片，没有清晰的图像输出，当人眼的肌肉无法将晶状体拉伸至正常位置时，也就是人们常说的近视眼，眼前的景物就变得模糊不清，摄像头与镜头的配合也有类似现象，当图像变得不清楚时，可以调整摄像头的后焦点，改变CCD芯片与镜头基准面的距离(相当于调整人眼晶状体的位置)，可以将模糊的图像变得清晰。镜头是摄像机的眼睛，为了适应不同的监控环境和要求，需要配置不同规格的镜头。比如在室内的重点监视，要进行清晰且大视场角度的图像捕捉，得配置广角镜头；在室外的停车场，既要看到停车场全貌，又要能看到汽车的细部，这时候需要变焦镜头。 摄像机镜头品种繁多，从焦距上可分为短焦镜头、中焦镜头、长焦镜头、变焦镜头；从视场大小分有广角、标准、远景镜头；结构上分有固定光圈定焦镜头、手动光圈定焦镜头、自动光圈定焦镜头、手动变焦镜头、自动变焦镜头、自动光圈电动变焦镜头、电动三可变镜头等。
