Laser-Induced Breakdown Spectroscopy (LIBS)
Asia Mattelab is the sole distributor for Lightgo Laser Induced Breakdown Spectroscopy (LIBS) in Singapore and South East Asia (Malaysia, Thailand, Vietnam, Indonesia, Philippines). Lightigo s.r.o. is a start-up company focused on the development and production of the analytical instruments for the Laser-Induced Breakdown Spectroscopy, one of today’s most promising technique of elemental analysis. Lightigo was founded in August 2019 by the researchers and hardware developers who have the long-term experience with the R&D in the field of LIBS.
Laser Induced Breakdown Spectroscopy (LIBS) is a rapid chemical analysis technology that uses a short laser pulse to create a micro-plasma on the sample surface. This analytical technique offers many compelling advantages compared to other elemental analysis techniques. A typical detection limit of LIBS for heavy metallic elements is in the low-PPM range. LIBS is applicable to a wide range of sample matrices that include metals, semiconductors, glasses, biological tissues, insulators, plastics, soils, plants, soils, thin-paint coating, and electronic materials.

SyncRay - Digital Delay Generator
Your nifty box for precise synchronization
Syncray is a digital delay generator designed to create and manipulate delays or echoes of sound signals. The device takes an input audio signal and reproduces it after a specified amount of time, creating a repeated, delayed version of the original sound.
Syncray offers various parameters and controls to shape the delay effect. It allows the user to adjust the delay time, determining how long the repetition occurs after the initial sound. Additionally, it provides options to control the feedback, which determines the number of repetitions and their decay over time. This feature adds depth and texture to the delayed sound.
Moreover, Syncray may have additional features like modulation, filtering, and synchronization capabilities. Modulation introduces subtle variations to the delayed sound, creating a more dynamic and evolving effect. Filtering allows the user to shape the frequency content of the delay, emphasizing or attenuating specific ranges. Synchronization enables the device to synchronize the delay time to a tempo or external clock source, ensuring precise rhythmic repetitions.
Precise analysis requires precise synchronization. With the SyncRay, our compact Digital Pulse (Delay) Generator (DPG), you can synchronize up to 5 instruments with nanosecond precision. SyncRay has been designed as a compromise between cheap DPGs, which lacks some important features and more advanced DPGs, which are too big and/or too expensive.
