SPECTRAL CAPABILITY

Choose the band that reveals the information you need.

Each spectral family is developed for a distinct combination of illumination, target characteristics and detection task.

Visible-light imaging scene 01 · NATURAL COLOR

Visible Light

High-resolution color imaging for observation, recognition and monitoring under conventional illumination.

View visible-light lenses Near-infrared imaging scene 02 · LOW-LIGHT DETAIL

Near Infrared

Enhanced target contrast in low illumination and with active near-infrared supplemental lighting.

View near-infrared lenses Short-wave infrared imaging scene 03 · MATERIAL RESPONSE

Short-Wave Infrared

Material, moisture and surface-feature observation where visible contrast alone is insufficient.

View SWIR lenses
