Product Name:Neutral Density Attenuation Filter
English Name:Neutral Density Attenuation Filter
Aliases:ND Filter, Neutral Density Filter, Attenuator
Physical Properties:The neutral density attenuation filter is an optical component that uniformly attenuates incident light intensity over a broad spectral range through specialized optical coatings, with transmittance showing minimal variation with wavelength. It features high surface accuracy and excellent parallelism, typically fabricated on premium K9 glass or fused silica substrates, suitable for visible to near-infrared bands. By adjusting coating thickness and formulation, various fixed or variable optical density (OD) values can be provided to meet different light attenuation requirements.
Uses:It is used for laser power adjustment and beam attenuation to protect optical components and detectors from intense light damage. It is widely applied in optical inspection instruments, spectroscopic analysis systems, biomedical imaging, and light intensity adjustment and calibration in optical experiments.
Technical Specifications:
Square size range: 2mm×2mm to 200mm×200mm; Round size range: ф2mm to ф300mm; dimension tolerance ±0.1mm
Parallelism: 3 arcsec to 3 arcmin; surface accuracy: λ/10 to 1λ (λ=632.8nm)
Surface quality: 60/40 (MIL-O-13830); clear aperture ≥90%
Coating: custom neutral density film with various OD values available; substrate options include K9 glass, fused silica, UV-grade fused silica, etc.
Spectral range: covers UV to near-infrared, compatible with multiple laser wavelengths
