0.088X/0.176X Dual-Magnification Bi-Telecentric Lens
The POMEAS PMS-DTC-0088/0176-120 integrates 0.088X and 0.176X imaging channels into one dual-port bi-telecentric optical system. Two cameras can operate simultaneously, allowing the machine vision system to capture a large overall field while inspecting critical features at a higher magnification.
With a fixed 120 mm working distance, up to Ø100 mm field of view and 0.05% TV distortion, the lens is designed for high-precision measurement and complete inspection of large components.

Key Optical Features and Engineering Benefits
- 0.088X and 0.176X dual magnification: Combines large-field observation and higher-magnification feature inspection without changing lenses.
- Dual-camera ports: Supports two cameras operating simultaneously to output two different magnifications for separate measurement requirements.
- Bi-telecentric optical design: Reduces perspective and magnification errors during dimensional measurement.
- Up to Ø100 mm field of view: Enables complete observation of large components in a single imaging cycle.
- 0.05% TV distortion: Helps maintain stable geometric imaging for edge extraction and dimensional analysis.
- 120 mm working distance: Provides installation space for fixtures, lighting and automated handling mechanisms.
- Low-distortion and extended-DOF design: Improves imaging stability when components have height variation or positioning fluctuation.

System Compatibility and Integration
The PMS-DTC-0088/0176-120 provides two C-Mount camera interfaces and supports two cameras operating simultaneously. The camera sensor format, pixel size, required field of view and smallest measurable feature should be evaluated together before final system configuration.
The lens can be integrated with compatible industrial machine vision cameras. Suitable lighting should be selected according to the material, surface reflectivity and required measurement feature.
Customization and Technical Support
OEM/ODM customization can be evaluated according to the required field of view, working distance, sensor format, mechanical interface and illumination configuration. Custom projects are subject to technical evaluation and minimum order requirements.
Use the POMEAS telecentric lens selection tool to compare available magnifications and optical configurations.
