BTL-150M Series 90° Turning Telecentric Lens | Large Format Machine Vision Lens

Product Description 90° Turning Telecentric Lens for Space-Constrained Machine Vision Systems The BTL-150M Series is a high-performance 90° turning telecentric lens engineered for precision machine vision applications where installation space is limited. Its folded optical path enables flexible integration into compact automation equipment, multi-axis inspection systems, and confined production environments without compromising imaging accuracy. Supporting image sensors up to Φ67.6mm, the BTL-150M Series is ideal for large-format industrial cameras requiring a wide field of view and high-resolution performance. Multiple working distance (WD) options from 288mm to 465mm provide greater flexibility for system design and optical layout optimization. With MTF30 >100 lp/mm, the lens delivers exceptional image sharpness, high contrast, and accurate edge reproduction, making it ideal for semiconductor inspection, precision metrology, wafer measurement, and other demanding machine vision applications.
