Ocean Optics Launches DH-mini Light Source

New light source delivers high intensity broadband light in a compact package
Dunedin, Florida, USA (March 3, 2014) – Now available from Ocean Optics is the DH-mini light source. This compact, high-intensity source for spectroscopy combines deuterium and tungsten halogen sources in a single optical path, producing stable output across the UV-VIS-NIR from 200-2500 nm. The versatility of the DH-mini is ideal for demanding applications in the quality control and life science industries, especially fiber probe-based measurements where light throughput is a challenge, and absorbance measurements of high optical density solutions.

DH-mini

The DH-mini high-intensity source for spectroscopy combines deuterium and tungsten halogen sources in a single optical path.

As one of the pioneers of combination UV-VIS-NIR sources for spectroscopy, Ocean Optics has refined the new DH-mini, making it significantly more powerful, stable and compact than previous generations of comparable light sources. The DH-mini has nearly 3.5x greater output than earlier combination deuterium-tungsten halogen sources, expanding its usefulness to include absorbance measurements over a wide wavelength range and facilitating the measurement of multiple different samples with a single light source.

In addition to producing high-intensity output, the DH-mini operates with great stability (0.2% peak to peak) and minimal drift (0.1%/hour after stabilization). This mitigates the need to disturb experiments for frequent reference-taking and helps to ensure that results are reliable. Galvanically isolated electronics help to eliminate electronic cross-talk that can interfere with operation.

The DH-mini’s small footprint – 75 mm x 82 mm x 175 mm (3.0” x 3.25” x 6.875”) and 0.5 kg (1.1 lb.) — helps to free up laboratory bench space and makes it easily adaptable for OEM devices. The DH-mini has great operational flexibility, allowing users to optimize configurations without having to switch among multiple sources or change sampling accessories. For example, each source bulb can be operated independently, with variable voltage controls for adjusting deuterium and tungsten halogen intensity. The built-in shutter allows users to make reference and dark measurements without disturbing the stability and thermal equilibrium of the lamp, a problem when a source is turned off or on. This saves time and increases the accuracy and precision of the measurement.

Users can operate the DH-mini bulbs and shutter manually via controls on the front panel or remotely via 15-pin TTL connection. Remote control via TTL connection simplifies integration and operation of the light source a when external triggering and other functions are required.

The DH-mini complements Ocean Optics’ range of modular spectroscopy solutions for a wide range of applications. By configuring the DH-mini with a wide-range spectrometer and appropriate accessories, users can create a multifunction spectroscopy system for UV, VIS or NIR measurements or for measurements where broad-range response is necessary.

For kinetics researchers and scientists requiring fast, full spectrum acquisitions, the QE Pro provides onboard buffering capability. The 15,000 spectra onboard buffer maintains data integrity by buffering time-stamped spectra for USB communications. Buffering enables full-spectrum kinetics measurements, such as those used in chemical and enzyme kinetics or protein folding to be performed every 8 milliseconds — or 125 measurements per second.

Thermoelectric control of the detector improves the stability of the detector for lengthy measurements, where thermal noise convolutes the signal. TEC cooling dramatically reduces thermal noise and holds QE Pro’s stability to 4 dark counts over a 60 °C ambient temperature range. This stability allows the spectrometer to be used for demanding online and at-line quality control measurements and environments susceptible to temperature changes.

QE Pro spectrometers are also available with replaceable, precision laser-cut slit and aperture assemblies for SMA 905 and FC connectors. Replaceable slits give users more freedom in spectrometer design and the ability to switch among applications such as fluorescence and absorbance as easily as replacing a few screws. The slits are available with SMA 905 or FC connectors and are available separately or as part of a kit comprising one each of 5 µm, 10 µm, 25 µm, 50 µm, 100 µm and 200 µm width slits and one SMA bulkhead with no slit installed.

Ocean Optics Introduces Integrated Raman Spectrometer

IDRaman reader uses optical focusing method to overcome Raman sampling challenges
Dunedin, Fla. (October 16, 2013) – The IDRaman reader from Ocean Optics is a fully integrated Raman system with Raster Orbital Scanning (ROS) technology, an innovative sampling technique that enables more efficient Raman signal collection with lower background effects.

IDRaman reader

Ocean Optics IDRaman reader.

ROS overcomes sampling hurdles associated with dispersive-design Raman devices by maintaining high resolution and minimizing the power buildup of a tightly focused laser typical in Raman applications. As a result, users can exploit a larger sample interrogation area for more precise identification of delicate samples such as surface enhanced Raman spectroscopy (SERS) substrates, and use lower laser power to avoid issues associated with delicate or unstable samples such as explosives.

The new instrument debuted September 29, 2013 at SciX 2013, an industry event that covers analytical chemistry, with an emphasis on emerging technologies. SciX, which was held in Milwaukee, Wisconsin, attracts a mix of scientific and engineering experts from around the world.

The IDRaman reader is available with 638 nm, 785 nm or 808 nm laser excitation and comes in two resolution options. A high-resolution 4 wavenumber version covers the Raman spectrum from 200-2000 wavenumbers and is a good option for extracting detailed spectral information near the laser line. For broader spectrum coverage, an 8 wavenumber version covers 200-3200 wavenumbers and is especially useful for wide-range samples such as ethylene, acetylene and other aliphatic hydrocarbons (non-aromatic compounds).

The IDRaman reader has a convenient sampling setup for measuring surfaces below the instrument, for measuring solutions in cuvettes, and for measuring other samples from the top, sides or bottom of vials.

The new instrument debuted September 29, 2013 at SciX 2013, an industry event that covers analytical chemistry, with an emphasis on emerging technologies. SciX, which was held in Milwaukee, Wisconsin, attracts a mix of scientific and engineering experts from around the world.

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.

Replaceable Slit Spectrometers Offer Applications Versatility

Field-replaceable slits add flexibility to Ocean Optics spectrometers
Dunedin, FL (August 9, 2013) – Precision laser-cut slit and aperture assemblies from Ocean Optics add flexibility to the company’s QE65 Pro, Jaz, and Torus miniature spectrometers. Replaceable slits give users more freedom in spectrometer design and the ability to switch easily from one application to another with the replacement of a few screws.

Ocean Optics QE65 pro

Modular spectroscopy makes possible thousands of applications by mixing and matching optical bench and other components in various configurations. The availability of field-replaceable slits in the Jaz, Torus and QE65 Pro spectrometers adds another layer of customer flexibility.

Spectroscopy is a technique in which the design criteria exist as a set of trade-offs. The optimal spectrometer depends upon the application. For some users, one of the most vexing trade-offs involves the choice of entrance aperture (slit). 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, without the need for realignment. For example, 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. Or a Torus configured to resolve closely aligned emission peaks for one application can be adjusted make low light level measurements for another application.
