0.16X/0.7X Bi-Telecentric Lens, 1-Inch Sensor, 120mm WD

0.16X/0.7X Dual-Magnification Bi-Telecentric Lens

The POMEAS LTDC016/07-120 combines a 0.16X large-field imaging channel and a 0.7X high-resolution inspection channel in one bi-telecentric optical system. It enables machine vision systems to capture the overall dimensions of a large component while inspecting smaller critical features with higher image resolution.

With a fixed 120 mm working distance, 0.02% TV distortion and support for sensors up to 1 inch, the lens is designed for precision dimensional measurement of mobile phone screens, watch glass, semiconductor components and other large or high-value parts.

Key Optical Features and Engineering Benefits

• 0.16X and 0.7X dual magnification: Combines large-field inspection and detailed feature measurement without requiring two completely independent optical systems.
• Bi-telecentric optical design: Maintains stable magnification when the object position changes within the available depth of field, reducing perspective-related measurement errors.
• 0.02% TV distortion: Helps preserve geometric accuracy across the image for reliable edge detection and dimensional measurement.
• 120 mm working distance: Provides installation space for fixtures, illumination and large workpieces.
• Up to 1-inch sensor compatibility: Supports larger-format machine vision cameras for wider fields of view and higher image utilization.
• Optional external coaxial illumination: POMEAS coaxial illumination can improve imaging of reflective or low-contrast surface features, including bosses, blind holes and polished components.

Technical Specifications

*Theoretical depth of field calculated with a 0.04 mm permissible circle of confusion. For optimum imaging performance, approximately half of the stated range is recommended in practical applications.

For general information about methods used to determine distortion in optical imaging systems, refer to ISO 9039:2008. This reference does not represent a claim of product certification.

Field of View by Sensor Format

Typical Applications

• Mobile phone screen outline and dimensional inspection
• Watch glass diameter and edge measurement
• Semiconductor chip and package inspection
• Precision component profile and feature measurement
• Boss diameter and blind-hole inspection with coaxial illumination

System Compatibility and Integration

The LTDC016/07-120 provides two standard C-Mount camera interfaces and supports two cameras operating simultaneously. The two optical channels output different magnifications to meet large-field positioning and detailed measurement requirements.

The lens can be integrated with compatible industrial machine vision cameras. Camera sensor size, pixel size, required field of view and smallest measurable feature should be evaluated together before selecting the final configuration.

Optional illumination components include a ring light, single-channel dimmer, telecentric backlight and lighting controller. External coaxial illumination can be configured for reflective surface inspection, while parallel backlighting is suitable for high-contrast silhouette and edge measurement.

Lens Selection and Technical Support

Use the POMEAS telecentric lens selection tool to compare available magnifications and optical configurations.

POMEAS also provides camera and lighting matching, sample imaging evaluation and application-based system configuration. OEM and ODM customization can be evaluated according to the required field of view, working distance, sensor format, mechanical interface and inspection target.
