Neutral Density Filters - Absorptive
Photonics Marketplace
UQG Optics absorptive Schott glass ND filters are used to control the intensity of light and are stackable without resulting in multiple reflections. The ND glass absorbs the light within the filter. Each glass type is polished to required thickness and measured to produce the exact optical density and transmission. Custom or standard optical density’s and transmission can be produced to a particular wavelength.
UQG Optics has a range of stock sizes for a quick delivery.
