Overview

Filter processing manufacturer Nahong Optoelectronics specializes in producing neutral density filters, optical glass ND attenuation sheets, and neutral density filters, also known as attenuation sheets, are filters that attenuate light intensity without changing the energy distribution of the spectrum. Neutral density filters can uniformly attenuate light intensity in a wide spectral range, and are coated with durable metal film layers on the surface. These filters can be applied in fields such as natural light and laser.

Nahong Optoelectronics specializes in productionNeutral density filter optical glass ND attenuator

Neutral density filter, also known as attenuation plate, is a filter that attenuates light intensity without changing the energy distribution of the spectrum. Neutral density filters can uniformly attenuate light intensity in a wide spectral range, and are coated with durable metal film layers on the surface. These filters can be applied in fields such as natural light and laser.

Neutral density filters are divided into absorption and reflection type density sheets and low reflection type density sheets (ND mirrors), which attenuate light in a wide spectral range and are particularly suitable for calibration of optical systems. The main types of neutral density filters include ultraviolet attenuation, visible light attenuation, and near-infrared light attenuation. We are a professional manufacturer of neutral density attenuation filters, providing a variety of neutral density attenuation filters with different wavelengths ranging from near ultraviolet to far-infrared.
