红外滤光片是一种光学元件,集成于前置摄像头模组中,用于选择性阻挡红外波长,同时透射可见光。它可防止红外干扰,避免数字成像系统中出现色彩失真、雾霾和对比度降低,确保准确的颜色再现和清晰的图像质量,适用于需要真实视觉表现的应用。 通过波长选择性吸收或干涉镀膜技术实现。滤光片材料或多层镀膜反射或吸收红外辐射(通常为700nm-1100nm),同时允许可见光(400nm-700nm)通过到达摄像头传感器。这种光谱分离防止红外光污染可见光图像数据。

Front camera modules require infrared filters because camera sensors are sensitive to both visible and infrared light. Without filtering, IR light causes color distortion, reduced contrast, and hazy images. The filter ensures only visible light reaches the sensor for accurate color reproduction.
Filter failure results in infrared contamination of images, causing color shifts (typically toward red/purple tones), reduced sharpness, poor contrast in daylight conditions, and inaccurate color representation in photographs and video.
Typically not user-replaceable as they are integrated into the optical stack during manufacturing. Replacement requires specialized equipment and calibration. In most consumer devices, filter damage necessitates complete camera module replacement.
