Product Description
The BTL-H1 Series Telecentric Lenses are high-performance optical solutions designed for large-format machine vision and precision metrology applications. Engineered for 1" (Φ16.6 mm) sensors, this series delivers ultra-low distortion, stable magnification, and high-resolution imaging across a wide range of working distances from 73 mm to 465 mm.
With magnification options from 0.638× down to 0.055×, the BTL-H1 series supports both medium and ultra-large field-of-view inspection systems. Its advanced telecentric design ensures extremely low distortion (<0.1%) and high telecentricity performance, making it ideal for high-accuracy dimensional measurement and industrial inspection.
Designed for demanding environments, the BTL-H1 series achieves excellent resolution performance (MTF30 up to 145 lp/mm) and supports long working distances for large-scale inspection setups. The robust C-Mount mechanical structure ensures easy integration into automated production lines and high-end machine vision systems.
