Overview
Olc C++ library intended to control Ophir® infrared lenses (Ophir® is registered trademarks of MKS Instruments, Inc. or a subsidiary of MKS Instruments Inc). The Olc library inherits Lens interfaces. The library has advanced auto focus functions. It includes source code of libraries: Lens interface library (provides interface and data structures to control lenses, Apache 2.0 license), Logger logging library (provides function to print log information in console and files, Apache 2.0 license) and SerialPort library (provides functions to work with serial ports, Apache 2.0 license). The Olc library provides simple interface to be integrated in any C++ projects. The library repository (folder) provided by source code and doesn't have third-party dependencies to be specially installed in OS. It developed with C++17 standard and compatible with Linux and Windows.

// Set Zoom speed to 10%.

lc->executeCommand(cr::lens::LensCommand::ZOOM_TO_POS, 10000);
