The OPOTEK Opolette 2940 Ultra-Compact MIR Laser is a rugged, pulsed-laser system that outputs 2940nm and is end-user installable. It uses optical parametric oscillator (OPO) technology to generate 2940nm laser light for water desorption-based mass spectrometric analysis or other related applications. At 2940nm the laser achieves a pulse energy of 6 mJ @ repetition rate of 20Hz.
Water is the primary component of biological samples relevant to life sciences. With Opotek‘s Opolette 2940, a micro-sized cross-section can be desorbed while keeping sample constituents intact. Ionization can occur directly or through the addition of a secondary ionization source, followed by mass spectrometric analysis. The Opolette 2940 is designed for custom or commercial ion source integration. An SDK is available to integrate laser functions into instrument software. The laser can be factory tuned to other absorption peaks between 2600 and 3450 nm on request.
