SENSORS & DETECTORS PRODUCTS

Gentec-EO introduces the HP15KW-TUBE, a high-power detector for laser power measurement up to 15,000 W. This detector, a high-power water-cooled meter, is less sensitive to variations in water cooling temperature than other comparable products in the market.

Ophir offers the PD300RM-UVA irradiance and dosage sensor is designed for measuring sources at different wavelengths simultaneously in the spectral range, without the need to know the exact wavelength. This laser radiometer can replace a traditional radiometer that is calibrated to a single wavelength.

Laser Components offer pyroelectric detectors designed to create an electric signal due to temperature changes in the chip. Deuterated Lanthanum α Alanine doped TriGlycine Sulphate (DLaTGS) detectors specifically exhibit the most effective pyroelectric effect known. Although there are many other possible uses, the major application for these detectors is FTIR spectroscopy.

Opto Diode offers a new ultraviolet-enhanced detector featuring UV detection between 190 nm and 400 nm spectral wavelength, with a full spectrum of 190 nm out of 1000 nm. The device features stable responsivity over wide temperature ranges and 100% internal quantum efficiency from 200 to 400 nm.

Ophir Photonics offers the 10K-W-BB-45 water cooled thermal power/energy laser measurement sensor designed for very high powers with a 45 mm aperture. The device can measure power from 100W to 11,000W and features a deflecting cone and annular absorber that withstands high power densities to 10kW/cm².

The UP19K-15S-H5-D0 is a thermal detector designed for laser power measurement up to 15 W. Its modular concept design increases the power capability with five different cooling modules.

The QE25SP-S-MT-D0 is a pyroelectric detector designed for laser energy measurements up to 3.0 J with a noise level down to 2 µJ for the MB coating. The modular design concept increases the power capabilities and uses two different cooling modules.

Ophir Photonics offers a series of wide spectral range photodiode laser measurement sensors for power ranges from 200 to 1800 nm within the UV and IR spectral ranges. Available models include the PD300-UV/IR without a filter for lowest powers from 200 to 1100 nm, the PD300-UV/IR with an installed filter for powers from 700 – 1800 nm, and the PD300-IRG for telecom wavelength fiber and free space measurements.

SENSORS & DETECTORS VIDEOS

  • The second generation of the INTEGRA is a meterless line of all-in-one detectors that combine a detector and a meter in one device that lugs directly into your PC. Each detector of the INTEGRA series offers the same incredible performance as the usual detector and meter combination, from pW to kW and from fJ to J. For a brief introduction on this product, watch the video.

  • On the last day of SPIE’s 2016 DCS exhibition in Baltimore, Kevin Fogarty with Canon showed us a 19 micron pixel pitch sensor that can achieve a full color and high definition image in extremely low light environments.

  • This year at SPIE’s DCS exhibition, Donna with DSI gave us a quick on-location hello from the show floor before turning it over to principle investigator Kevin Gibbons so that he could offer some advice on what you should consider before determining an optical coating’s specifications for sensing applications.

  • Marco Snikkers wrapped up our Photonics West 2016 coverage by introducing us to a pixel sensor that acts as an 8-channel spectrometer for biomedical, fluorescence marking, and colorimeter applications, as well as a multi-spectral camera that can monitor specific wavelengths in real-time.

  • Sensors Unlimited — UTC Aerospace Systems cut the ribbon on their new facility on September 17th, 2014. Doug Malchow spent a few minutes with us explaining how the move to a bigger and better place has already resulted in better quality imaging detectors with lower defects, lower bad pixel counts, and much lower dark current.

  • Jeff Eng, applications engineer with Hamamatsu, shows us a MEMS FTIR engine for IR spectroscopy instruments that works in applications involving gas sensing, materials analysis, and point of care devices. He also introduces us to 2D InGaAs image sensors for thermal imaging monitors, NIR image detection, and foreign object detection; compact radiation detectors; and more.

  • Excelitas and Qioptiq have joined together to provide custom optics manufacturing and a wide array of sensor offerings for various applications.
