Now available from Ocean Optics is the IDRaman micro, a compact microscope designed for Raman measurements in research, quality control and quality assurance environments. The IDRaman micro is a versatile, high-performance analytical tool for applications where sampling requires careful focus and high spatial resolution to optimize the Raman signal.
The IDRaman micro uses a novel focusing technique to make sampling more accurate and easier to perform than with systems based on traditional inverted microscopes and those that rely on fiber optic coupling. IDRaman micro's OneFocus feature optimizes the instrument for Raman sampling using the same focal plane for collecting images and Raman signals. The ability to focus for optimal Raman sampling while viewing a quality image of the sample simplifies the often tedious and inexact process of acquiring data from a specific structure or location on a sample. OneFocus also enhances data collection for applications where only a single layer of material is applied to the surface, such as graphene or surface enhanced Raman spectroscopy (SERS).
The IDRaman micro is available with either a 532 nm or a 785 nm laser for excitation and offers the option for a high-resolution detector with 4 wavenumber resolution acquiring data from 200-2000 wavenumbers, or a wide-range system with 8 wavenumber resolution acquiring data from 200-3200 wavenumbers. Its 3-megapixel imager collects crisp images using epi-illumination techniques and its interchangeable objectives allow users to adjust spot size and optical magnification.
Compared with traditional Raman microscopy setups, IDRaman micro has a compact footprint at just 4" x 14" x 11" (36 cm x 10 cm x 28 cm) and weighs 12 lb. (5.4 kg). Its flexible design makes it possible to measure samples in cuvettes and from the bottom or sides of vials. Switching between microscopy and bulk samples is as simple as pulling a lever.
