PMMA-Laminated Wratten ND Filters

PMMA-Laminated Wratten ND Filters are ideal for light attenuation in image-forming optical systems to reduce light intensity across the visible spectrum without altering the spectral profile. The laminated design offers additional stability and durability compared to traditional polyester/gelatin filters while remaining a lightweight alternative to traditional glass ND filters. These ND filters are available in 25mm or 48mm diameters and a thickness of 0.6mm. PMMA-Laminated Wratten ND Filters are uncoated and feature a blocking wavelength of 400 - 700nm with OD options of 0.1, 0.3, 0.5, 1.0, 2.0, and 3.0.
