STS Microspectrometer Provides Big Performance in a Small Footprint
Ocean Optics has introduced a family of low-cost, high-performance CMOS detector-based spectrometers that are ideal for embedding into OEM devices. Despite its tiny footprint – less than two inches square (40mm x 42mm) and one inch (24mm) high – STS provides performance comparable to larger systems: full spectral analysis with low stray light, high signal to noise (>1500:1) and typical optical resolution of ~1.5nm (FWHM). STS is a great option for a range of VIS-NIR applications including characterisation of LEDs and absorbance/transmittance of various samples and is ideal for OEM applications where one or more wavelengths are being monitored and highly reproducible results are necessary.
The STS Microspectrometer is available in standard models with 350-800nm and 650-1100nm wavelength coverage. Customisation of wavelength range, entrance aperture and other optical bench accessories is available for high-volume and OEM customers. Also, unlike other microspectrometers, STS has a built-in shutter for making dark measurements. Operating software is priced separately and provides a full range of spectroscopic functions as well as control of the shutter. Packages for developing customised software for STS are also available.
At the heart of the STS is a 1024-element CMOS detector in a crossed Czerny Turner optical bench. The bench is distinguished by specially designed collimating and focusing mirrors and a 600 lines/mm groove density grating. Its optical design and advanced CMOS detector elevate STS to performance levels comparable to larger and more expensive spectrometers. For example, STS has 14-bit A/D resolution and has low power consumption of just 0.75 W. Also, with customisation of the entrance aperture, optical resolution.

Breaking New Ground in Spectroscopy with New Near-Infrared Spectrometer
Photon Control, Inc is pleased to announce the release of the New SPM-001-NIR1700S/NIR2500W to Photon Control’s successful line up of Spectrometers. The SPM-001-NIR1700S/NIR2500W is a high-resolution 140mm focal length optical bench spectrometer featuring TE cooled 512 pixel InGaAs linear array and is available with two different detectors to enhance spectral range from 900nm up to 2500nm for expanding detection capabilities further into the near infrared. Boasting a longer focal length allows Photon Control to offer customisation for both wide and very narrow spectral ranges to the SPM-001 NIR1700S/NIR2500W.
SPM-001-NIR1700S/NIR2500W is well suited for a variety of applications such as mineral identification, petrochemical analysis, and pharmaceutical analysis to name a few. Photon Control’s Spectrometers are the only ones equipped with an internal DSP chip. This DSP chip is capable of handling complex signal processing tasks. It also features powerful software development kits. The SPM-001-NIR1700S/NIR2500W works extremely well with the SPL family of light sources and other accessories available at Photon Control.

Infrared Spectrometer to Meet Advanced Analytical Challenges
PerkinElmer, Inc announced the launch of the FrontierTM
Infrared
Spectrometer - a high performance infrared (FT-IR) spectrometer built using PerkinElmer’s industry-leading spectroscopy expertise. Part of a new family of spectrometers, the Frontier analytical platform meets diverse FT-IR challenges ranging from everyday measurements to the most advanced, complex analyses.
The instrument combines best-in-class sensitivity with flexibility for many diverse sectors, from polymers and chemicals to consumer goods and pharmaceuticals, helping to protect consumers and the environment across the world. Delivering unmatched respectability of transmission spectra, Frontier’s superb sensitivity and configurability ensure superior performance in demanding applications, helping to advance safe drug development, understand complex chemical and material properties, and meet the challenging requirements of research and academia.
Dusty Tenney, President, Analytical Sciences and Laboratory Services, PerkinElmer, commented: “With more than 65 years of experience in spectroscopy, PerkinElmer has now developed a specialised infrared spectroscopy platform that can be adapted for customers’ research requirements. With Frontier, multiple analyses can be conducted using a single instrument. From near- to far-infrared analysis, Frontier is our most powerful spectrometer to date.”
Frontier is a powerful, configurable FT-IR spectrometer that can be expanded as research goals develop. Offering more optimised sampling options than any other FT-IR in its class, Frontier’s optical flexibility enables the addition of a vast array of specialised accessories to meet a wide range of sampling challenges; whether checking for batch conformity or micro contamination.
A modular and upgradeable platform combined with exceptional signal-to-noise ratio assures optimal spectral performance for near-, mid- and far- infrared spectroscopic analysis. The unique automated range changing capability allows multiple techniques to be utilised at the touch of a button, with the flexible optical system also permitting the addition of microscopy and imaging systems for detailed materials analysis.
A range of patented PerkinElmer technologies enable the Frontier to produce superior infrared spectra. Atmospheric Vapor Compensation™ (AVC) features an advanced digital filtering algorithm designed to eliminate CO2
and H2 O interferences for accurate FT-IR
results. The fifth generation Dynascan™ fixed mirror-pair interferometer requires no dynamic alignment to compensate for errors in linear mirror movement. PerkinElmer’s AVI Standardisation™ calibrates spectrometer wavelength scales to a higher accuracy than achieved with conventional calibration methods.
