Product Family Description

Ideal for 250-700nm Sources
Optical Densities Ranging from 0.3 to 3.0

Our TECHSPEC® UV-VIS reflective neutral density (ND) filters are spectrally flat from 250 to 700nm and feature outstanding parallelism and surface characteristics. This combination of high tolerance and broadband performance makes these filters ideal for attenuating a wide range of sources. The filters are suitable for low power laser applications and can be stacked to obtain a variety of optical densities. Orient mirrored side toward source at 0° angle of incidence. Optical Densities of 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 available in a Pre-Loaded Filter Wheel.

TECHSPEC® UV-VIS Reflective Neutral Density Filter Kit

Each kit includes 8 filters in optical density values of 0.3, 0.5, 1.0, 1.3, 1.5, 2.0, 2.5, and 3.0. The kit is ideal for determining precise system optical density requirements. Custom densities are available for OEM applications.
