Linear Variable Filters

Linear Variable Filters (LVFs) are critical optical components that provide continuously variable spectral transmission across their surface, enabling advanced control and flexibility unattainable with conventional filters. By precisely tuning the illumination position on the filter, allowing seamless wavelength selection without physically changing the filter, making them indispensable for applications in biophotonics, spectroscopy, and hyperspectral imaging.

Materion offers a broad portfolio of LVFs engineered for exceptional spectral precision, stability, and customization.

Our Linear Variable Filters feature:

Continuous Spectral Tuning

LVFs enable smooth variation of transmission wavelengths along the filter surface, allowing users to finely adjust spectral response in real time. This capability is ideal for fluorescence imaging, multi-wavelength detection, and other applications requiring dynamic spectral control.

High Performance and Stability

With deep blocking achieved through reflectance and low absorption materials, our LVFs deliver excellent transmittance in the passband and maintain long-term spectral stability. Customizable dispersion profiles and filter sizes ensure optimal integration into diverse optical systems.

Lightweight, Compact Design

Designed for size- and weight-sensitive platforms such as unmanned aerial vehicles (UAVs) and portable sensing instruments, our LVFs combine compact form factors with robust performance.

With Materion’s Linear Variable Filters, engineers gain unparalleled spectral flexibility and precision, empowering innovation in optical sensing, imaging, and spectroscopy.
