About
Continuously Variable Filters (CVF)
A CVF is a specialized optical filter where the spectral response (the wavelength it lets through) changes continuously along its surface. By placing this "wedge" filter directly on an image sensor, engineers can create ultra-compact hyperspectral cameras without the need for bulky prisms or gratings.
Why it Matters for Industry
-
Size & Weight: Drastically reduces the footprint of HSI systems, ideal for drones and handheld devices.
-
Efficiency: High transmission and light collection compared to traditional dispersive optics.
-
Innovation: Supports real-time 3D hyperspectral data and high-speed industrial sorting.
