Ocean Optics Introduces Handheld Raman Spectrometer

Ocean Optics has released the IDRaman mini handheld Raman spectrometer, a small, powerful instrument with exceptional performance for sample authentication and counterfeit detection, identification and verification. The palm-sized IDRaman mini is rugged and dependable, delivering fast, accurate Raman analyses ranging from chemical and explosive agent detection in the field to quality assurance and quality control sampling routines in the laboratory.

The IDRaman mini overcomes many of the limitations of current handheld Raman instruments – especially size, sample measurement and power supply needs. At just 9.1 x 7.1 x 3.8 cm (3.6 x 2.8 x 1.5 in.) and weighing only 330 g (11 oz.), the IDRaman mini is not much larger than the typical mobile phone. To ensure simple and dependable operation during long field missions or manufacturing shifts where recharging is impossible, the IDRaman mini runs on two easily-replaced AA batteries.

The small size of the IDRaman mini does not limit its sample measurement performance. The unique Raster Orbital Scanning (ROS) mode scans a tightly focused beam over a wide sample area, dramatically improving the quality of the Raman measurement. ROS has benefits for liquid and solid samples, in particular solid samples that are inhomogeneous and irregularly shaped. Also, ROS is a dramatic improvement over stationary beam systems. The low average power needed eliminates sample damage and the possible ignition of explosive samples. In ROS mode, most compounds can be identified in less than nine seconds.

Featuring a bright 7.1 cm (2.8 in.) resistive touchscreen display, the IDRaman mini is easy to operate in bright sunlight and while wearing restrictive personal protection equipment. The straightforward, graphical interface is easy to navigate and allows operators of all skill levels to quickly acquire data. Sampling can be accomplished using either small vials or with a stand-off accessory for powders, residues, and solid samples.

The IDRaman mini helps make the power of Raman analysis more accessible, improving efficiency and saving on measurement costs.
