OPOTEK takes compactness and portability to the next level with the OpolucisTM AIR 2940. Based on diode-pumped solid state (DPSS) and optical parameteric oscillator (OPO) technology, the OpolucisTM AIR 2940 is all air-cooled, all-in-one laser designed for instrument integration or confined laboratory spaces that benefit from low RF noise equipment and cannot tolerate water cooled solutions. The 2940 nm wavelength is tuned to the maximum absorption of water and other molecules with -OH and -NH functional groups. Biomolecules relevant to life sciences can be ablated or desorbed intact for capture, ionization or other manipulations on the sub-millimeter cross-section scale.
