400–1200 nm Visible-SWIR Telecentric Lens | Focus Shift Correction TLVS-H1.1

Product Description

The Visible-SWIR Telecentric Lens Series is designed for high-precision imaging across a broad spectral range from 400–1200 nm, enabling seamless imaging from visible light to SWIR without refocusing. Featuring advanced focus shift correction, these lenses maintain sharp images across wavelengths, making them ideal for applications requiring both visible and near-infrared imaging.

Available in 0.7×, 1×, 2×, and 4× magnifications, the series supports image circles up to Φ24 mm and offers both coaxial and non-coaxial illumination configurations. By eliminating focal shifts between visible and SWIR wavelengths, these telecentric lenses reveal material differences and defects that are difficult or impossible to detect with visible light alone.

Designed for machine vision, semiconductor inspection, solar cell analysis, and scientific imaging, the Visible-SWIR Telecentric Lens Series provides reliable, distortion-free imaging for demanding industrial applications.
