Neutral Density (ND) Filter

 Absorptive Neutral Density (ND) Filter

Absorptive Neutral Density (ND) Filter

Different from reflective filters, absorptive neutral density filters use various neutral density optical glasses to offer a range of densities by controlling materials and thickness .These filters have low surface reflection and flat spectral response in the visible range. They can be widely used in spectral measurement, imaging optical systems, machine vision systems and optical output attenuation of low power lasers

Material Neutral grey glass

Transmitted Wavefront error λ/ 4 @ 633 nm

Parallelism ＜1 arcmin

Surface Quality 60-40

Dimensional Tolerance ＋0.0/-0.2mm

Thickness Tolerance ±0.5mm

Applied Wavelength Range 400~700nm

*Optical Density Tolerance ±5% @633nm

CA ＞90%

* Optical Density(OD) OD= -log(T/100) T
