Q: What sensor size does the BTLM-23 series support?
A: The BTLM-23 series is optimized for 2/3" sensors (Φ11 mm image circle) and is compatible with high-resolution industrial cameras.

Q: What working distance options are available?
A: The series offers 65 mm and 85 mm working distance options, allowing flexible integration into different machine vision systems.

Q: Can the depth of field be adjusted?
A: Yes. The lenses feature a variable iris, enabling users to optimize depth of field and image resolution according to inspection requirements.

Q: Are coaxial illumination models available?
A: Yes. Both coaxial and non-coaxial versions are available to accommodate different surface characteristics and lighting conditions.

Q: What applications are the BTLM-23 series designed for?
A: Typical applications include precision dimensional measurement, semiconductor inspection, AOI, electronics inspection, and industrial metrology.

Q: Why choose a bi-telecentric lens over a standard telecentric lens?
A: Bi-telecentric lenses eliminate magnification changes caused by object position variations, providing superior accuracy and edge definition for critical measurement tasks.
