PRODUCT UPDATE Spectroscopy Spectroscopy light sources

Thorlabs has released two fibre-coupled, broadband tungsten light sources (SLS201/ SLS202) for spectroscopy. The sources come in two versions, both featuring a constant intensity blackbody radiation spectrum that ranges from either 300nm to 2,600nm (Tungsten-Halogen) or 450nm to 5,500nm (Tungsten). The light sources have a built-in removable filter holder for standard 1-inch spectral filters. The internal feedback system of SLS201 and SLS202 stabilises the light power variation to within 0.05 per cent and reduces the power drift to 0.01 per cent per hour. This allows the

AFM-based IR spectrometer

Anasys Instruments has introduced the NanoIR2, a second generation AFM based IR spectroscopy (AFM-IR) platform. NanoIR2 operates with top-side illumination, eliminating the prior need to prepare samples on a ZnSe prism and enabling measurements on a more diverse set of samples. AFM-IR measurements have now been demonstrated on a broad range of samples including semiconductor devices, thin films, nanocomposites, data storage samples,

UV-visible-NIR spectrophotometer

Elliot Scientific has launched the 508 PV UV- visible-NIR spectrophotometer in the UK and Ireland. The product is designed to be added to the open photoport of a microscope or probe station for non-destructive analysis of the spectra of many types of microscopic samples. Featuring Craic Technologies’ Lightblades spectrophotometers and proprietary optical interface technologies, the 508 PV can acquire 8-megapixel, high-resolution colour images and the spectra of microscopic sample areas

Laser systems Tau marking machine

Cielle has expanded its range of laser products with the Tau laser marking machine. It is available in two versions, featuring either a fixed or mobile work table. The laser marking machine reduces the number of operations needed to complete a processing cycle, bringing savings in terms of both time and costs. Tau’s compact dimensions make it suitable for restricted space requirements. It is suitable for small workshops and professionals that require reliable, precise and versatile tools. The machine can mark various materials including brass,


gold, silver, steel and aluminium, and can be used to engrave key rings, medals, bracelets, earrings and trinkets in general, with high precision. It is effective for customised marking to give highly detailed finishes. Moreover, the 50W source makes it possible to cut precious materials and metals. The aluminium work table with T-shaped grooves has special clamps for securing the pieces being engraved in place, and can be either fixed inside the machine, or rotated so as to allow

the operator to load new pieces while the marking machine is already running.

Desktop laser marking system

Illuminar Technologies has launched a compact DSP-controlled desktop laser marking system ideal for adding barcodes, logos and labels to a variety of surfaces. The Predator series incorporates Illuminar’s digital signal processor based laser control system and a high-quality laser source. The desk-top laser system also has an optional vision system which means the machine can mark items in random orientations.

user to work for longer periods of time without needing to take another reference measurement. The broadband spectral power

distribution expands the applications for these light sources to the near-infrared or mid-infrared spectral range. The performance of Thorlabs’ stabilised light sources makes them suitable for experiments that require high accuracy and stability, such as transmittance and reflectance measurements.

minerals, tissue sections and polymer blends. Additionally, the NanoIR2 provides a resonance- enhanced mode, which significantly increases the sensitivity of the technique and enables AFM-IR measurements on samples of sub-20nm in thickness.

The NanoIR2 system combines the nanoscale spatial resolution capabilities of a powerful full-featured atomic force microscope (AFM) with infrared spectroscopy’s ability for chemical characterisation and identification.

Field-replaceable slits for


Ocean Optics has launched precision laser-cut slit and aperture assemblies to add flexibility to the company’s Jaz, Torus and QE65 Pro-miniature spectrometers. Field- replaceable slits give users more freedom in the spectrometer design and the ability to switch from one application to another easily. A larger slit increases throughput, but at the expense of optical resolution. A smaller slit yields higher optical resolution, but decreases throughput. Typically, changing the slit requires spectrometer rework that has to be performed at the manufacturer’s facility. With replaceable slits, users can change the spectrometer’s performance directly in the field. Changing slits can be accomplished within minutes. QE65 Pro users who need great sensitivity for low light applications, such as fluorescence, can change slits from a larger slit size to a small one, avoiding saturation in absorbance applications.

Ultraviolet spectrometer

by absorbance, reflectance, polarisation, luminescence and fluorescence.

Applications include characterisation of new materials, measurement of surface plasmon resonance, graphene, vitrinite reflectance of coal and high-resolution

colourimetric and relative intensity mapping of flat panel displays.

McPherson has released its ultraviolet spectrometer, Model 234/302, with cooled, sensitive CCD detectors featuring integral UV order sorting filters. The spectrometer features adjustable slits, scanning, and a selection of diffraction gratings. Ultraviolet spectroscopy is useful for process or quality control, UV laser development, optical test and measurement, and luminescent phosphor characterisation.
