Product Overview
The POMEAS LTC2-150 is a fixed-magnification 2.0X object-side telecentric lens designed for dimensional inspection, precision positioning and industrial machine vision.
Its object-side telecentric optical design helps reduce perspective-related magnification variation when the inspected part changes position within the usable depth range. Combined with 0.03% TV distortion and a 150±5 mm working distance, the lens is suitable for PCB inspection, connector inspection, display alignment, fine-feature observation and precision positioning.
Key Benefits
Provides a small object field for detailed machine vision inspection.
Helps reduce perspective error and magnification variation caused by object-position changes.
Supports stable image geometry for dimensional inspection and positioning.
Provides useful clearance for samples, fixtures and illumination.
Compatible with industrial cameras using sensor formats up to 1/2 inch.
Designed for precision positioning and detailed industrial inspection.
Supports convenient integration with compatible industrial machine vision cameras.
Provides a reference usable depth range for optical system evaluation.

Field of View
Because the LTC2-150 uses fixed 2.0X optical magnification, the final object-side field of view depends on the active dimensions of the selected industrial camera sensor.
| Camera Sensor Format | Reference Object Field |
|---|---|
| 1/4 Inch | Approx. 1.6 × 1.2 mm |
| 1/2 Inch | Approx. 3.2 × 2.4 mm |
Actual field of view should be confirmed using the camera's effective sensor dimensions rather than the nominal inch-format designation alone.
Why Use an Object-Side Telecentric Lens?
Conventional machine vision lenses introduce perspective: features closer to the lens appear larger than features farther away. This can create measurement variation when the position or height of the inspected object changes.
An object-side telecentric lens limits this perspective effect and helps maintain a more stable magnification within its usable object-space range. This makes LTC2-150 useful for dimensional inspection, edge measurement, positioning and applications where repeatable image geometry is important.
Mechanical Details
Typical Applications
Precision observation and positioning of PCB features and component structures.
Suitable for fine-pitch terminals, connector wiring and small mechanical features.
Supports positioning and alignment of small display and electronic structures.
Low distortion and telecentric imaging support repeatable edge and coordinate positioning.
2.0X magnification provides detailed imaging for small inspection areas.
Object-side telecentricity helps improve image-scale stability for measurement applications.
Camera and Optical System Integration
The LTC2-150 supports C-Mount industrial cameras with sensor formats up to 1/2 inch. Camera sensor dimensions, pixel size, required field of view and measurement accuracy should be evaluated together before final selection.

Frequently Asked Questions
What type of telecentric lens is the LTC2-150?
The LTC2-150 is a fixed 2.0X object-side telecentric lens designed for precision machine vision inspection, positioning and measurement.
Which cameras are compatible with LTC2-150?
It supports standard C-Mount industrial cameras with sensor formats up to 1/2 inch. Camera model, active sensor dimensions and pixel size should be confirmed before final selection.
What field of view can the lens provide?
The documented object field ranges from approximately 1.6 × 1.2 mm with a 1/4-inch sensor to 3.2 × 2.4 mm with a 1/2-inch sensor. Actual FOV depends on the camera's active sensor dimensions.
What is the working distance?
The specified working distance is 150 ± 5 mm.
What is the TV distortion?
The specified TV distortion is 0.03%.
Is LTC2-150 a bi-telecentric lens?
No. LTC2-150 is specified as an object-side telecentric lens. For applications requiring strict object-side and image-side telecentricity, a dedicated bi-telecentric lens should be selected.
Does the lens include a camera or external coaxial light?
No. The lens, industrial camera, external illumination and mounting accessories should be selected and quoted according to the application requirements.
What information should I provide for lens selection?
Please provide the camera model or sensor dimensions, pixel size, required field of view, target dimensions, working distance, object height variation and required inspection or measurement accuracy.
Confirm Your Optical Configuration
Send your camera model, sensor dimensions, pixel size, required field of view, target size, working distance and inspection accuracy for compatibility confirmation.
