greenTEG and Pacer USA

Pacer USA has been selected to partner greenTEG - a developer and manufacturer of innovative thermal sensor solutions.

The company was founded in 2009 as an ETH Zurich spin-off and has since built up an international customer base. greenTEG uses a production technology which allows to industrially manufacture thermoelectric elements with a very high density of thermocouples. greenTEG’s thermal sensors are integrated into diverse applications by customers active in markets such as laser, building technologies, medtech, automotive, processing industry and R&D.

greenTEG will launch new high-precision laser power detectors at Laser World of Photonics China in March 2015. The new product line (gRAY) features housed, mounted, and bare die sensors for wavelength-independent laser power measurements. Full technical details and datasheets for greenTEG’s laser power detectors will be uploaded on this website as soon as the products are launched.

PVG Pulsed Laser Diodes

Excelitas PVG series of high power pulsed laser diodes are multi-quantum well devices with active layers fabricated using advanced MOCVD epitaxial growth techniques.

Devices are offered housed in two convenient hermetic package configurations. The “S” style package is a TO-18 style low inductance package (~ 5.2 nH) and the “R” style is a CD 9 mm outline providing increased thermal dissipation with the option of accommodating a rear facet monitor photodiode.

This series of devices are wavelength centered at 1550 nm primarily to take advantage of a significant increase over AlGaAs and InGaAs lasers in the maximum permitted emission level with respect to Laser Institute of America or International Electrotechnical Commission (IEC) requirements.

The output wavelength of this series is well matched to the near peak spectral response of Excelitas InGaAs photodiodes types C30617H, C30618H, C30619H, C30645H and C30662H, amongst others.

Silicon Photomultipliers from Excelitas

Excelitas now offers high photon detection efficiency Silicon Photomultipliers (SiPMs) within their low light level detection portfolio.

SiPMs are arrays of parallel, interconnected avalanche photodiodes (APDs) which benefit from low-noise, low-cross-talk and ultra-fast timing resolution. Operated in a voltage range above the breakdown voltage, they provide high Photon Detection Efficiency (PDE) from near UV to NIR wavelengths. SiPMs allow multiple photons to be detected and counted within the same timeframe, and offer high linearity and high dynamic range.

One of the biggest advantages of SiPMs - as compared to traditional photomultiplier tubes (PMTs) – is their high immunity to electromagnetic fields.

Excelitas’ SiPMs are suited to high-volume applications in:

    PET Imaging

    Single Photon Emission Computed Tomography (SPECT)

    High Energy Physics

    Radiation Detection

    Fluorescence Detection

    Analytical Instrumentation

Focal Sweep Videography

A paper by variable focus lens manufacturer Optotune presents a focal sweep telephoto camera which is potentially of interest in defence and security applications, among others.

The system is enabled by Optotune’s liquid polymer based deformable optics.

A focal stack is a sequence of images captured with different focus settings. A number of cameras have been introduced that sweep the focal plane using mechanical motion in order to capture a focal stack. However, mechanical motion makes video capture impractical and is unsuitable for long focal length cameras, as large sensor travel poses serious practical issues.

This new Optotune paper presents a focal sweep telephoto camera that uses a variable focus lens to sweep the focal plane. The camera requires no mechanical motion and is capable of sweeping the focal plane periodically at high speeds. Optotune’s prototype camera has been used to capture Extended Depth of Field (EDOF) videos at 20fps, and to capture periodic focal stacks which can be used for several interesting applications such as video refocusing and trajectory estimation of moving objects, potentially of interest in security and defence applications. Telephoto imaging (e.g., scenes with depth range on the order of 10’s to 100’s of meters) is an area where focal sweep could be particularly useful because telephoto lenses typically have a narrow DOF.

Deformable optics can open the door for focal sweep videography. The fast response time of deformable optics enables periodic focal sweep at high frequencies. As a result, deformable lenses are particularly well suited for focal sweep cameras with large focal lengths, which would require large sensor motion using the swept-sensor approach.
