Additional LIBS Components
LIBS Sample Chamber
The LIBS-SC Sample Chamber is a key component of a LIBS system and is designed to perform various functions safely and in clear view of the sample. The LIBS-SC has an eyewear-safe enclosure. The chamber has a safety-interlock so the laser will not fire when the door is open. It houses a manually controlled x-y-z stage and provides illumination for the optional LIBS-IM-USB Imaging Module. The LIBS-SC has an inert gas induction port and a suction nozzle to remove particulates. In addition, you have the ability to

The LIBS-SC includes an evacuation system that removes material from the sample area. You also can feed gases such as argon into the chamber. Flooding the chamber with an inert gas provides greater sensitivity for many elements.

The LIBS-IM-USB Imaging Module directly attaches to the LIBS-SC Sample Chamber to enable users to magnify a sample image and to establish a laser ablation target on the sample. The camera is also useful when you want to adjust the laser focus at the surface of the sample, or above or below the sample surface. When used with the LIBS-SC and laser, the LIBS-IM-USB and laser are in the same focal plane enabling precise, rapid and convenient laser focus. The USB-enabled color camera captures pre- and post-ablation images of the sample and provides up

LIBS Laser Options
We offer two LIBS25000 laser power options from industry leader Big Sky Laser Technologies. Laser ablation and plasma formation are very specific to the sample matrix, and therefore the power requirements will vary by sample type. For most applications we employ a Q-switched 1064 nm Nd:YAG laser, and for maximum versatility, we recommend a 200 mJ laser with attenuator to adjust the laser power according to the sample matrix. The choice of laser power and wavelength depend on the material being analyzed and the sample's tolerable damage threshold. The LIBS-LASER is a 50 mJ CFR Nd:YAG laser for metal and thin film samples. The LIBS-LAS200MJ is a 200 mJ CFR Nd:YAG laser for most all other materials.
