Ocean Optics Contributes to Gulf Air Quality Monitoring in Wake of Deepwater Horizon Spill

Argos-spectra blog

HR2000 used in Argos portable UV DOAS air monitoring system
Dunedin, Florida (June 14, 2010) – Modular HR2000 spectrometers from Ocean Optics are enabling air quality monitoring in the Gulf of Mexico as part of Argos Scientific’s portable UV DOAS air monitoring system.  Argos Scientific is working in conjunction with Hillsborough County, Florida, to monitor the environmental impact of the Deepwater Horizon oil spill in the Gulf of Mexico.

The project has special significance to Ocean Optics as the company is located on the Gulf side of Florida and its community will be affected in coming months as the oil advances, upsetting both water and air quality.

Ames Photonics: Si Photodiodes and ultrashort laser pulses

Oculus

Recently, Ames Photonics have investigated the feasibility of using silicon photodiodes, like their Oculus USB photodetector, for detecting femtosecond laser pulse energy output.

Silicon photodiodes offer potential advantages for the detection of ultrashort laser pulses. However, until now, no reliable information about saturation energy level, practical energy density and linearity of photodiodes under ultra-short laser pulse exposure has been available in the literature.

The results show that Si photodiode have several advantages compared to other commonly used photosensors, including:

  • Excellent linearity of output current as a function of incident light
  • Very high sensitivity-can typically resolve pJ levels
  • Spectral response from 190 nm to 1100 nm (Si), longer wavelengths with other semiconductor detectors

Edmund Optics Image Rotation Prisms

Half  Penta Prisms

Edmund Optics TECHSPEC® Half Penta Prisms are used to deviate the line of sight by 45° without inverting or reverting the image. The reflecting surface is aluminized and over-coated with Inconel and black paint to increase the prism's efficiency. When combined with a corresponding TECHSPEC® Schmidt Prism, a Pechan Prism pair is formed. The Pechan Prism will invert or revert the image while not deviating the line of sight. The Pechan prism can be placed in converging or diverging light allowing for system size reduction.

Edmund Optics Deformable Mirrors correct spherical aberration

Edmund Optics

Edmund Optics , the premier provider of optical components, has introduced new high performance Deformable Mirrors. These mirrors are the easiest and most convenient tool to correct optical aberrations through wavefront manipulation and control. They are ideal for use in combination with wavefront sensors and real-time control systems in adaptive optics. This particular deformable mirror has 32 radially packed actuators. There is more than 10µm (typically 14µm) of actuator max stroke. They are suited for tabletop applications as well as OEM integration. Priced considerably less than competing products, EO’s Deformable Mirrors are in-stock and available for immediate delivery for fast turnaround and excellent value.

These versatile mirrors will be featured in a special demonstration available for viewing at the EO Booth 1909 during CLEO/QELS 2010, May 18-20, 2010 at the McEnery Convention Center in San Jose, CA. The demonstration will show the integration of a deformable mirror into a PBS-based Twyman-Green Interferometer. By replacing the traditional test surface with a deformable mirror, one can better illustrate the deformations of the mirror’s surface. These small changes in the surface of the mirror create variations in the interferogram. Additionally, this set up highlights how optical noise can be reduced by simply reducing the amount of back reflections in the system.

Toptica: A Passion for Precision

 

 

 

 

 

Toptica have launched an all-new website. Like their products, it bristles with smart design and crisp engineering. It includes detailed product descriptions, as one would expect, in addition to many extras including extensive applications notes (in quantum optics, biophotonics, microscopy, terahertz and semicon inspection), a seriously helpful "Laserfinder" feature, and a library of very detailed troubleshooting guides and technical manuals.

Dr. Thomas Renner, VP Sales & Marketing said: "We are quite excited about the new key visual from the field of snooker and billiards. It perfectly symbolizes the world of colorful photons and atoms, physics, our company logo and last but not least our slogan A Passion for Precision.” OPTICA engaged 5 time German champion and TOPTICA neighbor Thomas Gollowitsch as billiard model.

And if all of that is not quite enough to encourage visitors to click through to the new site, Toptica have hidden a small picture of Albert Einstein, somewhere on one of the many online pages. If you can find it, you're in the running to win a free iPad . We're still looking.

Ames Photonics S-cube: The Versatile Imaging Spectrometer

Ames Photonics S-cube

The new Ames Photonics S-cube is a versatile, low-cost, imaging spectrometer which offers a level of performance flexibility previously available only in much more expensive systems. It is intended to fill a gap in the market between entry-level spectrometers with limited capability to adjust key parameters, and systems providing flexibility but at significant cost. The S-cube offers a middle way: a reasonably priced spectrometer with excellent performance and wide versatility in a compact, modular package.

Together with Ames Photonics range of LARRY and GARRY linear array detectors and other components, the S-cube provides the spectroscopist with a highly flexible modular platform, making it an ideal choice for every spectroscopy laboratory.

Based on a Folded Czerny-Turner layout, the system has been engineered from the ground up with the goal of allowing for quick and convenient interchange of components. Diffraction gratings, input slits and array detectors can all be replaced, allowing the S-cube to be easily and rapidly reconfigured for a very wide range of spectral measurements. Wavelength recalibration of the system after such configuration changes is achieved via a semi-automated routine employing onboard Hg/Ar and tungsten spectral calibration lamps.

The S-Cube is suitable for general spectroscopy, but it has been specifically optimised with laser spectroscopy in mind. High F/# and low coma ensure high resolution and low distortion of spectral lines. Further performance flexibility is provided by the ability to vary astigmatism across the wavelength spectrum.

Applications:

  • Femtosecond laser spectroscopy (pump probe, CARS, photon echo
  • Versatile, modular research spectrometer for UV-VIS-NIR
  • Excellent platform for teaching spectroscopy and spectral calibration
  • Absorption and reflection measurements in VIS-NIR using onboard tungsten lamp coupled to optical fibre
  • Measuring emission spectra

Thorlabs release new Adaptive Optics Kit

Thorlabs Wavefront sensor

Thorlabs have announced the release of new Adaptive Optics Kits. These kits provide out-of-the-box functionality for real-time, high-precision wavefront measurement and control, and include:


  • Deformable Mirror (Multi- or Mini-DM)
  • Shack-Hartmann Wavefront Sensor (shown above)
  • All Imaging Optics and Associated Mounting Hardware
  • Fully Functional Stand-Alone Control Software for Immediate Control of the System
  • A Low-Level Support Library to Assist with Tailored Applications Authored by the End User

Thorlabs offers four Adaptive Optics Kit options, two that incorporate 140 actuator Multi-DM deformable mirrors and two that incorporate 32 actuator Mini-DM deformable mirrors. AOK1-UM01 and AOK2-UM01 contains a DM with a gold mirror coating, while AOK1-UP01 and AOK2-UP01 contain a DM with an aluminum mirror coating. When combined with the WFS150-5C wavefront sensor, these kits are designed for use in the 600 - 1100 nm range and the 400 - 1100 nm range, respectively. Regardless of the kit chosen, the three constituent components provide a closed-loop sample rate of 8 Hz when in the correction mode. Although the use of DMs in astronomy is well known, these miniature, precision wavefront control devices are also helping researchers to make breakthroughs in beam forming, microscopy, laser communication, and retinal imaging.
