Product DescriptionProduct DescriptionA neutral density filter is a specialized optical component designed to uniformly attenuate incident light intensity without altering its spectral composition (color). It is typically fabricated from optical glass, quartz, or plastic substrates, achieving attenuation through metal ion doping (absorptive type) or neutral absorption coatings (reflective type). Performance is characterized by optical density (OD) and transmittance (T%): OD is defined as OD = -lg(T%), e.g., OD=1 means 10% transmittance, OD=2 means 1% transmittance. Unlike color filters, ND filters attenuate all wavelengths equally, making them ideal for scenarios requiring light intensity control without color distortion, such as photography, laser power adjustment, optical measurements, and astronomical observation. They can be designed as fixed density (e.g., OD0.3, OD1.0) or variable density (adjustable via rotating polarizers), with some models featuring laser damage resistance for high-power-laser-applications.SpecificationProduct NameNeutral Density FilterAngle of Incidence0 DegreeThickness0.5~3.0mm or CustomDimensionCustomSurface Quality60-40TransmittanceTavg=3% or CustomWavelength400-1100nm or CustomOptical Density:(OD) OD=log10 (1/T)Optical Applications?· Photography & Videography:· Shooting with large apertures in bright conditions (e.g., shallow depth of field in daytime)· Long-exposure photography (e.g., capturing water motion or star trails)· Controlling shutter speed in video to avoid overexposure· Laser Systems:· Adjusting laser power to safe levels for detectors· Balancing intensity across multiple optical paths· Optical Measurements:· Calibrating photodetector sensitivity· Controlling incident light for spectrometers to prevent saturation· Astronomical Observation:· Dimming bright celestial objects (e.g., the Sun, planets) to protect equipmentCompany ProfileTianjin Fushi Optics Co., Ltd.Tianjin Fushi Optics Co., Ltd. is a comprehensive optoelectronic enterprise integrating R&D, production, sales, and after-sales service.
