BTLM-23 Coaxial Optional 2/3" 0.4X 0.5X C-Mount Telecentric Lens for Precise Inspection

Product Description

BTLM-23 Series Bi-Telecentric Lenses for High-Precision Measurement

The BTLM-23 Series Bi-Telecentric Lenses are specifically designed and optimized for high-accuracy measurement and inspection applications. With true bi-telecentric optical design, these lenses ensure consistent magnification, minimal distortion, and precise edge definition, making them ideal for demanding metrology tasks.

Supporting 2/3" (Φ11 mm) sensors, the BTLM-23 series offers flexible working distance options of 65 mm or 85 mm, allowing easy adaptation to different system layouts. The lenses feature a variable iris, enabling users to fine-tune depth of field (DOF) and resolution based on specific inspection requirements.

Designed with a large F-number, these lenses are well suited for use with high-resolution industrial cameras, ensuring excellent image uniformity and clarity. Additionally, users can choose between coaxial and non-coaxial illumination versions, enhancing flexibility for different surface inspection needs.

With a robust and manufacturing-friendly design, the BTLM-23 series is easy to integrate into industrial systems, providing stable and reliable performance in automated environments.
