High-Precision Bi-Telecentric Lenses (C-Mount)
<0.01° Ultra-Low Telecentricity | 0.2X - 2.0X In-Stock | 0.02% Optical Distortion
- Absolute Metrology Grade: True bi-telecentric design (<0.01° telecentricity) eliminates perspective parallax and sensor-tilt errors for strict dimensional gauging.
- Exceptional Image Fidelity: 0.02% optical distortion and high MTF (>0.4 @ 100lp/mm) ensure sharp edge detection for sub-micron algorithms.
- Industrial Robustness: Anodized aluminum housing (-20°C to +80°C) featuring a standard 110mm working distance and internal M62×0.75 filter threads.
- 100% Export Compliant: In-stock range (0.2X – 2.0X). Germanium-free and ITAR-free for a secure B2B global supply chain.

Product Overview
True Double Telecentricity
Unlike standard telecentric lenses that only correct entrance pupils, our Bi-Telecentric series corrects both object and image space. Even if your industrial camera's sensor is mounted with a slight mechanical tilt, or the inspected object experiences vertical vibration on the conveyor, the dimensional magnification remains 100% locked.
Harsh Environment Stability
Weighing a solid 320g, the heavy-duty anodized aluminum body ensures absolute optical axis stability under heavy industrial vibrations. Engineered with a wide thermal operating range (-20°C to +80°C) and front M62 filter threads, it thrives inside hot stamping facilities and harsh machining environments.
Reliable, Risk-Free Supply
We understand that continuous production relies on a predictable supply chain. By strictly focusing on civilian-use optical components and explicitly avoiding export-restricted materials like Germanium, our export processes are highly streamlined. We deliver globally compliant, ready-to-assemble optics directly to your factory floor or third-party integrators.
Metrology & Performance Reports

Metrology Analysis & Application Fit
- Target Spectrum: Optimized for broadband Visible to Near-Infrared (VIS-NIR) wavelengths.
- Resolution Assurance: Resolving down to 16.5μm (on 0.2X models) with an exceptional MTF (>0.4), ensuring your vision software experiences zero binarization threshold errors when measuring ultra-fine contours.
- Primary Applications:
- High-precision metrology of silicon semiconductor wafers
- Non-contact gauging of internal threads, micro-gears, and fasteners
- Dimensional verification of stamped smartphone mid-frames
- Medical device micro-component profiling
One-Stop Metrology Calibration Bundles
To unleash the full <0.01° telecentric potential of this lens, precise spatial calibration is mandatory. Alongside our in-stock bi-telecentric lenses, we manufacture matching High-Precision Machine Vision Calibration Targets (including standard 50x50mm chrome-on-glass plates certified to ±5um accuracy). Bundle your lens with a matched target to achieve plug-and-play sub-micron measurement right out of the box.
