TriAngle NIR

DESCRIPTION

TriAngle Focus - Focusing Electronic Autocollimator

The TriAngle NIR electronic autocollimators are based on the standard TriAngle design but employ NIR LED illumination for the reticle. The TriAngle NIR electronic autocollimators are commonly used for applications which require measurement at the design wavelength in the NIR.

It is used for measurements on material which only transmit light in the NIR range, such as are used in night vision devices. Another application is the laser beam alignment of lasers that emit light at a wavelength in the NIR spectral range.

SOFTWARE

OptiAngle: The Complete Software Package for Angle Measurement

The software OptiAngle® is a powerful tool covering all aspects of accurate angle measurement with the TriAngle electronic autocollimators in terms of measurement, control and analysis of the angular data. The well organized and modern menuguided user interface assists even the inexperienced operator to perform accurate measurements and to obtain repeatable results. A large set of pre-defined standard measurement applications is integrated into OptiAngle® which cover all established measurement techniques in optical and mechanical industry. In addition, customized measurement routines can be easily developed and embedded either by TRIOPTICS or the experienced end user. All OptiAngle® measurement functions can be further used in other common applications like Lab-View or Visual Basic (Excel).

TriAngle modular software concept

OptiAngle® Programming Interface (API)

In addition to the above scripting mechanism, the OptiAngle® functions can be embedded into a larger measurement framework which then can take control over the full functionality of OptiAngle® measurement applications.

OptiAngle® features an open software concept and programming interface which allows for the flexible and easy integration into other software environments. The angle measurement functions of TriAngle autocollimators can thus be integrated into almost any existing measurement application. In contrast to the scripting technology the user himself is enabled to develop the interfacing between the TriAngle autocollimator and his governing application. OptiAngle® functions are executed either by sending commands via serial port (RS232) or TCP/IP, or directly using the DLL based C programming interface (API). Existing sample applications and the comprehensive documentation demonstrate the control of TriAngle autocollimators by LabView, VBA, Excel. TRIOPTICS will be happy to assist the user to integrate the TriAngle functions into his own application.
