The Race To The Starting Line: Edge-Emitting Diode Lasers vs. VCSELs For The Automotive Lidar Market
The Race To The Starting Line: Edge-Emitting Diode Lasers vs. VCSELs For The Automotive Lidar Market
The competition to be the leading diode laser source for automotive lidar is not a race to the top, but rather a race to the starting line. Before reaching the goal to implement lidar ADAS in consumer vehicles by 2020, there must be at least one year of certification and testing before going to market.   Continue Reading..

SENSORS & DETECTORS PRODUCTS

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.

Ophir Photonics offers a series of very sensitive thermal power/energy laser measurement sensors designed with very low noise and drift to measure very low powers and energies. Available models include those calibrated for Terahertz radiation, those with a removable window, and those for divergent beams with windows that block infrared.

The RM9 series of radiometers are designed to use a pyroelectric or photodiode sensor in conjunction with chopped CW or quasi CW radiation, using a digitally synthesized lock-in amplifier to reduce external noise to a minimum. The signal is passed through the 18 Hz chopper and the chopped signal is detected by the sensor. All signals not at the 18 Hz frequency are suppressed.

Gentec-EO offers the largest selection of calibrated laser energy sensors for the measurement of laser powers from nanojoules to several tens of joules per pulse. They are offered in standalone formats, where the electronics are integrated in the device, or as standard sensors that can be hooked up to an energy meter.

  • Integra 2nd Gen Introduction

    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.
