Introduction: Neutral density filter, also known as attenuator, is a filter that attenuates the light intensity without changing the energy distribution of the spectrum. The neutral density filter can attenuate the light intensity uniformly in a wide spectral region, and the surface is plated with a durable metal film. This type of filter can be used in natural light and laser fields.

The neutral density filter is divided into two types of absorption and reflection, which attenuate light neutral in a larger spectral range. It is also particularly suitable for the calibration of optical systems.

The main types of neutral density filters are ultraviolet attenuation, visible light attenuation, and near-infrared light attenuation.
