Focuslight Launches FocusTest™ Series, Laser Diode Test and Analysis Systems


Download specifications:

Test and analysis equipment plays an important role in cutting-edge research for high power diode lasers, and is an effective tool in the development and mass production of high performance, high reliability diode lasers. Mastering test and analysis technology is key to understanding fundamental issues and complex problems when working with diode lasers. 

Using real-time, precision analysis and diagnosis, test and analysis tools can establish key indicators of high power diode laser performance, such as product power, efficiency, reliability, as well as basic parameters. This process also provides feedback and guides R&D and manufacturing, solving key technical problems as diode lasers are created, greatly improving product performance and reliability. 

As a leading supplier of high power diode lasers and laser optical components, Focuslight is also committed to the development of high-performance equipment for testing, burn-in, and lifetime testing, and to provide reliable support for the development and mass production of high power diode lasers. 

Focuslight is pleased to introduce the FocusTest™ Series of diode laser testing and characterization equipment. Five models include: 

• FocusTest LD Characterization Test System for automatic testing of LIV and spectrum and polarization degree; includes automatic data recording and report generation.

• FocusTest Far Field Test System for testing distribution of radiation intensity within ~120˚ field angle at the far field of the laser testing source.

• FocusTest Near Field Test System for testing intensity distribution of each emitter at the cavity facet.

• FocusTest Polarization Test System for automatic testing of polarization degree; includes automatic data recording and report generation.

• FocusTest Diode Laser Unmounted Bar Test System for characterization of laser diode photoelectric parameters, such as LIV, spectrum, and far field features of emitters on unmounted chips.
