New Development Kit for Spectral Sensing Applications from Ocean Optics

STS spectrometer, Raspberry Pi microcomputer and flexible software for out-of-the-box use.

Ocean Optics has introduced a new set of spectral sensing tools for developers and others who want to deploy spectroscopy in new applications. The STS Developers Kit brings together its powerful STS spectrometer, a Raspberry Pi microcomputer, customizable software and wireless capabilities in a single package for integrating spectral sensing quickly and easily. Right out of the box, the kit can be quickly configured for a variety of scientific, process monitoring and environmental applications. Uses include developing handheld devices for light metrology or colour measurement, creating cloud connected measurement clusters, and even mounting on UAVs for remote monitoring.

The STS Developers Kit takes advantage of the Raspberry Pi’s flexibility and adaptability to enable new uses for spectroscopy. Once connected to a WiFi network, the spectrometer can be controlled through phone, tablet, or computer web browser. The WiFi range is up to 150 m, and all data is securely stored to the onboard SD card. While it comes pre-loaded with this simple interface and is ready to use out of the box, the development platform makes it fast and easy to customize the kit to specific projects.

The web scripting API enables quick development of custom scripts and applications, allowing the STS and Raspberry Pi to perform even more complex tasks. Ocean Optics SeaBreeze drivers communicate directly to the spectrometer via USB interface. A Daemon Service software enables more autonomous functionality as well as coordination with other hardware such as switches or even controlling sampling accessories.

The core of the kit is Ocean Optics’ STS microspectrometer. At less than 42 mm square and 24 mm high, the STS delivers maximum power in a small footprint. Its optical design and advanced CMOS detector elevate the STS to performance levels comparable to larger and more expensive spectrometers. Excellent linearity, high dynamic range, and wavelength accuracy ensure reproducible and repeatable results. In addition, high thermal stability performance and low baseline drift ensure that data stays accurate, even under changing environmental conditions. The STS Developers Kit offers the choice of three STS models: STS-UV (190-650 nm), STS-Vis (350-800 nm) and STS-NIR (650-1100 nm).

Eye Check from Volk a Portable Ophthalmic Exam Tool

Mobile, handheld instrument aids in pediatric examination of Strabismus Amplitude.

Volk Optical’s Eye Check, an electronic handheld ocular measurement device, aids in the diagnosis of ophthalmic abnormalities. Capable of a number of key measurements including pupil diameter, horizontal visible iris diameter, inter-pupillary distance, margin reflex distance, pupil eccentricity and strabismus angle, Volk Eye Check helps practitioners screen, diagnose and document ocular characteristics for contact lens fitting and general diagnostic purposes.

Volk Eye Check

Volk Eye Check’s intuitive user interface is easily navigated by physicians and support staff for seamless integration into the practice environment. Its real-time, accurate and objective results enable quick decision making and can be output to electronic records management systems with Wi-Fi connectivity.

For general diagnosis and documentation, Volk Eye Check measures:
• Inter-pupillary distance for eyeglass fitting
• Margin reflex distance for detection and documentation of ptosis in endocrine disorders, as well as pre- and post-surgical comparison
• Strabismus angle for Amblyopia and Strabismus screening with objective documentation of Strabismus amplitude

Volk Eye Check can also help to quickly identify patients that are candidates for specialty lenses and reduce practice drop-out rates. An estimated 6 million contact users drop out of lens wear each year, 12 percent of those due to the discomfort of poorly fitting lenses1.

Eye Check measurement parameters that facilitate lens fitting are:
• Horizontal Visible Iris Diameter (HVID) to assess correct contact lens diameter
• Pupil diameter and eccentricity for GP lens fitting and multi focal contact lens choice
• Lid margin to pupil margin for bifocal lens fitting

Mahadev Dhuri who is launching Volk Eye Check in India adds: “Volk has a tremendous reputation in ophthalmic lenses and diagnostic imaging devices. In India, pediatric ophthalmic devices can play a critical role in early diagnosis of eye diseases. Also, in the rural interiors and even in smaller towns, you require a portable device for diagnosis. This innovative ophthalmic diagnostic device can also find many other applications in general patient care.”

Ocean Optics Spectrometers measure vegetation from the ground and the air

A pair of super-lightweight miniature spectrometers from Ocean Optics is helping researchers investigate plant parameters in a verdant patch of New Zealand grassland. The compact STS model spectrometers, one deployed as a ground unit and the other aboard an unmanned aerial vehicle (UAV), are making synchronised hyper-spectral measurements of barley and sugar beet crops to assess plant characteristics for more effective crop management.

A multinational team of researchers from Germany, Italy, Spain and New Zealand developed the UAV-based system and conducted the initial experiments, gathering high-resolution reflectance spectra from the UAV at altitudes of up to 200 meters and irradiance spectra from the ground-based spectrometer. According to team leader Andreas Burkart of the Research Center Jülich IBG-2 Plant Sciences, Germany, collection of hyper-spectral data by field spectroscopy is a time-consuming task and often is restricted to easily accessible areas.

The small size and weight of the STS spectrometer is ideal for use on the UAV, which allows a series of fast and reproducible measurements over any terrain, even forest or marsh. By measuring various segments across a section of the New Zealand pastureland, the system was able to assess information such as specific plots that contained live vegetation.

The STS is a remarkably small CMOS detector-based spectrometer that is less than 2 inches square (40 mm x 42 mm) and weighs a little over 2 ounces (68 g). It performs comparably to larger systems, providing full spectral analysis with low stray light, high signal to noise (>1500:1) and excellent optical resolution. For the application described here, the researchers were able to match the performance of the STS to that of a larger, more expensive commercially available field portable spectrometer, with optical resolution of ~2.5 nm (FWHM).

90 Year Old British Company that’s a World Leader

Age is no barrier to innovation, as Hanovia proves on its 90th birthday

For almost 90 years Hanovia Limited, tucked away on a Slough Trading Estate, has been quietly innovating.

Now as it approaches its 90th anniversary, the company is a world leader in the specialised field of UV water disinfection for applications like food and beverage processing, pharmaceutical manufacturing, brewing, swimming pools, buildings, ballast water and fish farms.

To celebrate this anniversary Hanovia is hosting a special event at the company’s HQ in November 3rd. The event includes a presentation by the current Managing Director, John Ryan, a factory tour for the guests, a cake cutting ceremony besides others and will also have the Mayor of Slough, where Hanovia is headquartered in UK, in attendance.

A bit of history…

Before Hanovia – the Slough Connection
Sir William Herschel first discovered ‘invisible radiation’ (infrared rays) in Slough in 1880. His discovery led to Johann Wilhelm Ritter’s discovery of ultraviolet radiation in Germany a year later.

Hanovia and UV
Hanovia’s history goes back to the early 1920’s, when the company started manufacturing UV lamps in Slough for medical treatment. ‘Actinotherapy’ or ‘artificial sunlight’ gained popularity after it was found that it cured rickets and helped in the healing of wounds. From then on, no hospital could afford to be without UV equipment. Hanovia was also one of the innovators of air disinfection using UV.

From those early days, Hanovia has evolved into one of the world’s leading manufacturers of UV lamps and systems for water disinfection in the industrial, leisure, building, aquaculture and shipping industries.

Hanovia’s timeline
1924 – The British Hanovia Quartz Lamp Co Ltd is founded in Slough, holding various patents and manufacturing rights across the British Empire
