surface, but also to look deep inside transparent samples and even obtain 3D images. A complete Raman spectrum is acquired at each image pixel, resulting in images consisting of tens of thousands of spectra. The acquisition time for one spectrum is only in the range of milliseconds, resulting in complete images being collected in a matter of minutes. When analysing dedicated peak characteristics of the spectra, a variety of images can be generated using only a single set of data. This allows you not only to image the distribution of chemical compounds, but also to analyse, for example crystallinity or material stress properties.

Photonics product development company ZiNIR has unveiled its Solo Spectroscopy, next generation spectrometer at Photonics West. Based on the concept of a resonator-based, diode-integrated
spectrometer chip, the Solo Spectroscopy technology offers the only spectrometer where both dispersion and detection functions are co-located within a single structure. It uses a high-Q microdisk resonator etched into a monolithic chip. Since photons do not need to travel between a grating (or mirror) and a detector, the opportunity for stray light is reduced. The main benefit of monolithic chip-based spectrometry is its robustness: it can sustain extreme temperatures and conditions, has no electrical or mechanical moving parts and has low power and footprint requirements.

Edinburgh Instruments’ photonics division demonstrated its LifeSpec II fluorescence spectrometer at Photonics West. Designed for both fundamental research and routine laboratory applications, the LifeSpec II utilises Time Correlated
Single Photon Counting for the measurement of fluorescence lifetimes from a single measurement. Its novel optical design produces zero temporal dispersion, allowing the instrument to measure ultra- fast decays down to 5ps. This fully automated spectrometer was equipped with a high repetition-rate picosecond laser for the show, and visitors were able to see profiles build live on screen, thanks to the integrated ultra-fast data acquisition and analysis software.

Newport has announced the OptoFlash, a miniature, multi- channel, spectrometer engine for applications requiring the detection of light energy at multiple wavelengths. OptoFlash is ideal for spectroscopy instruments designed for applications such as immunodiagnostic testing, environmental monitoring,
colorimetry, and other applications where a single component is required for easy integration into a new or existing OEM discrimination/ detection system. This new, demultiplexing optical engine is easy to customise and configure with as many as 10 wavelength channels, selected from 24 standard wavelength options ranging from 200-900nm. It is also available in 16 standard configurations that are commonly used in immunodiagnostic instrumentation. Originally developed for clinical chemical analysers, the OptoFlash provides high speed and high linearity with minimal stray light. It provides simultaneous optical transmission information for each wavelength channel, making it an ideal solution for OEM applications that require a small (51 x 16 x 25mm), and lightweight (only 30g), single-package device.
