红外滤光片技术

了解Visualplas红外光学解决方案背后的科学原理。我们的先进材料能够实现精确的波长控制,适用于下一代传感和成像应用。

红外通过滤光片

允许特定波长透过,同时阻挡不需要的光线

红外通过滤光片 are designed to transmit infrared radiation within specific wavelength bands while effectively blocking visible light and other unwanted spectral regions. This selective transmission makes them essential for applications requiring precise IR detection without interference from ambient light sources. 我们的红外通过滤光片采用先进的多层薄膜镀膜技术,在目标波长范围内实现90%以上的透射率,同时对阻挡波长保持大于4.0的光密度。

Wavelength range: 700nm – 1100nm Transmission: >90% Blocking OD: >4.0

红外截止滤光片

防止相机和传感器中的红外光干扰

红外截止滤光片 (also known as IR Cut filters) are essential components for digital imaging systems. They block infrared wavelengths that can cause color distortion and image degradation in CMOS and CCD sensors. 我们的红外截止滤光片具有陡峭的截止特性和出色的可见光透射性能,确保智能手机摄像头、安防摄像机和机器视觉系统中的准确色彩还原。

Cut-off wavelength: 650nm – 700nm Visible transmission: >92% IR rejection: >99%

红外反射膜

高效反射红外光,适用于智能设备和工业应用

红外反射膜s provide superior thermal management by reflecting infrared radiation away from sensitive components. Unlike absorptive filters, reflective films minimize heat buildup and are ideal for applications requiring efficient thermal control. 我们专有的镀膜技术能够在宽泛的红外波段实现高反射率,同时在可见光波长保持光学清晰度,使其非常适合智能窗户、汽车玻璃和显示应用。

IR reflectivity: >85% Visible transmission: >70% 厚度:50-200微米
