Stellarnet has released its Stellarscope system, a high performance and affordable surface enhanced Raman spectrometer (SERS) substrate for use with its line of Raman spectrometer systems. The company has also added several features to its Ramulaser series of Raman lasers.
The SERS substrates intensify Raman emission through plasmonic resonance, boosting signal by many orders of magnitude and enabling detection levels as low as parts per trillion for certain samples. Stellarnet’s substrates are low cost due to the unique nanostructure deposition process. The substrates offer flexible and quick sample application in the form of pipetting, dipping, or swab, with no required sample drying.
Stellarnet’s Stellarscope system allows users to couple their spectrometer system to a microscope. This enables users to perform Raman, fluorescence, and CIELAB colour measurements on a micro spot and capture high resolution images, video, and time lapse video of their samples. The system comes equipped with an Olympus research microscope with 4, 10, and 40x objectives, CMOS 1.3-megapixel camera, optical switch, and required SMA couplers and attachment accessories for specific applications.
The company has also added features to its Ramulaser series of Raman lasers. Most notably the 785nm and 1,064nm Ramulaser is now equipped with a power adjustment dial for operation in step increments to the highest 499mW output power. This is good for use with Raman samples that have low burn tolerances such as organic material, dark surfaces, and SERS substrates. The adjustable power feature allows users to maximise signal while keeping within sample thresholds.
The Ramulaser has also been equipped with a rugged metal enclosure and an eight hour battery pack for portable use.
