ImageMaster® PRO ST Industrial Optical Transfer Function (OTF) Measurement System | Specialized for MTF Testing of Smartphone Telephoto Lenses

Manufactured by TRIOPTICS Germany, the ImageMaster® PRO ST is a dedicated system for high-throughput measurement of MTF and other optical parameters of telephoto lenses used in smartphones. It is optimized for testing samples with long effective focal lengths under narrow field-of-view (FOV) conditions.

Key Features：

* Specifically designed for near-infrared (NIR) measurements
* Up to 200 virtual cameras, replacing the need for a physical single camera
* High-precision defocus (field curvature) control* Flexible measurement point selection across the sample
* Optimized for small FOV lenses, supporting full fields up to 24°
* Measurement of samples with focal lengths from 10 mm to 35 mm, using a 100 mm effective focal length telescope

* Single telescope setup enables dense measurement point coverage across the entire field, with simplified configuration
