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

Product Description Visible–SWIR Telecentric Lens with Focus Shift Correction for Precision Imaging The TLVS-H1.1 Series is a high-performance Visible–SWIR telecentric lens designed for advanced machine vision applications requiring imaging across a wide wavelength range from 400 to 1200nm. Its unique focus shift correction technology ensures consistent image focus from visible light to shortwave infrared (SWIR), eliminating the need for refocusing during multi-spectrum inspection. This series enables users to capture both visible and transmitted SWIR images with high stability, allowing the detection of internal structures and defects that are invisible under standard visible-light imaging. It is particularly effective for silicon wafer inspection and IC internal circuit imaging at ~1100nm transmission wavelength. Available in 0.7X, 1.0X, 2.0X, and 4.0X magnifications, the TLVS-H1.1 series supports both coaxial and non-coaxial configurations, providing flexible integration for different industrial inspection systems. Key Features ✔ Visible–SWIR Wideband Imaging (400–1200nm) Supports seamless imaging from visible light to SWIR spectrum. ✔ Focus Shift Correction Technology Maintains sharp focus across multiple wavelengths without adjustment. ✔ Telecentric Optical Design Ensures distortion-free imaging and high measurement accuracy. ✔ Multi-Magnification Options (0.7X–4.0X) Flexible configurations for various machine vision applications. ✔ IC Silicon Transmission Imaging (~1100nm) Enables internal circuit inspection through silicon wafers. ✔ Coaxial / Non-Coaxial Versions Available Suitable for reflective and transmissive inspection systems.
