Linear Variable Neutral Density Filter

Analog Precision: Tuning Light Intensity with Linear Gradients

The VenusLab VLLND Series is designed to overcome the limitations of "discrete attenuation." In many experiments, fixed optical density filters (e.g., OD0.1, OD0.5) cannot provide the exact transmission required. The VLLND utilizes linear gradient coating technology to distribute optical density across a 76.2mm length.

The beam's position determines the attenuation level, making intensity adjustment as intuitive as using a "sliding rheostat." With a surface quality of 80-50 and rigorous deviation testing (±5%) at 632.8nm, this series ensures research-grade reliability.
