basic information
**Features** ○ CF-A type It transmits over 85% of visible light and reflects over 85% of light with a wavelength of 1μm, making it effective for utilizing light around 1μm. For example, it provides thermal protection for halogen lamps or xenon lamps that have high spectral energy near 1μm. Additionally, it can be directly coated on condenser lenses, integrating the functions of the lens and filter. ○ CF-B type This type has the same coating as the CF-A type but uses heat-absorbing glass for the substrate. It is effective for utilizing light with wavelengths shorter than infrared. ○ NIC-A, B These are thermal cut filters that cause less thermal damage than the CF-B type. They also reflect near-infrared light, allowing for color correction of visible light. They can be directly processed for use in imaging tube windows and lenses. ○ Hot mirror A transparent conductive film that efficiently reflects thermal energy radiated from heat sources. ○ UV-IR cut filter A filter that transmits visible light while simultaneously reflecting ultraviolet and near-infrared light.
