Frequently Asked Questions
What is a Neutral Density (ND) Filter?
A Neutral Density (ND) filter is an optical device designed to reduce or attenuate the intensity of all wavelengths of light equally, without altering the color or spectral profile of the light source.
What does Optical Density (OD) signify?
Optical Density (OD) measures the transmission of light through the filter. A higher OD value signifies lower light transmission. For example, an OD of 0.1 allows approximately 79% transmission, while an OD of 1.0 allows 10% transmission, and an OD of 5.0 allows 0.001% transmission.
What is the wavelength range for these visible light ND filters?
These stock ND filters operate across a broad wavelength range of 400nm to 1100nm, covering both the visible light spectrum and a portion of the near-infrared (NIR) spectrum.
Can I get custom sizes or optical densities that are not listed in stock?
Yes. If your application requires custom dimensions, specific shapes, or non-standard Optical Density (OD) levels, please contact our team directly for custom manufacturing services.
In what applications are these ND filters typically used?
They are widely used in imaging systems, camera exposure control, laser power attenuation, optical calibration, spectroscopy, and to protect sensitive optical sensors from saturation.
