PPO - Model LIBS -Laser Induced Breakdown Spectroscopy

Laser Induced Breakdown Spectroscopy measures the atomic emission of samples. A laser pulse is used to generate a plasma burst from the sample. The atoms in the super heated plasma emit photons which are then analyzed with an optical spectrometer. LIBS measures mostly atomic emission lines, but the appearance of these lines is greatly affected by transient effects and the nature of the sample, so that even very similar molecular compounds may be distinguished relatively easily.

The PPO Laser Induced Breakdown Spectroscopy (LIBS) spectrometer system is the most sensitive available on the market. Our high efficiency transmission grating combined with our patented optical design maximizes the number of photons reaching the ICCD detector. Its rugged structure with no moving parts makes it an ideal system for field use such as remote detection applications for defense, security and border patrol.

Higher sensitivity and robust design enables the detection of substances and longevity of device. Some key benefits to the system are:

• In smaller quantities
• Further away
• Modular design for multiple different LIBS setup from benchtop to remote LIBS with telescope objective.
• Rugged design for immediate field use (no moving parts)

Volume phase holographic transmission grating technology maximizes the number of photons reaching the detector and dramatically reduces “noisy photons” which contribute in masking weak Raman signals. P&P Optica’s proprietary transmission grating fabrication process produces the best transmission gratings on the market today. The following figure compares PPO’s grating with two leading competitors.
