Osram has introduced green and blue laser diodes in TO-38 and TO-56 metal can packages. “The laser diodes are available with different optical power levels: 10, 20, 30, 50 and 100mW,” according to component distributor Rutronik, which is stocking the parts. “To ensure eye protection, the green laser diodes in the TO56 housing have an integrated photodiode that monitors and ...
Osram has introduced a green laser diode as a replacement for red lasers in human-visible applications such as levelling, scanning and dot projection. Called PLT5 522EA_Q it “enables manufacturers to benefit from the 4x brighter appearance of a green laser compared to red”, according to the company. “The laser has been tested for lifetime at 70°C [and] its ratings are ...
Osram has introduced a laser diode for industrial lidar. SPL TL90AT03 emits 905nm infra-red and has been developed for short laser pulses – between 5 and 100ns – maximum duty cycle is 0.1%. Optical output is 65W from a 110µm aperture (20A 100μs 1kHz) – said to be an efficiency of 34%. There are three emitters inside the package – forward ...
Rohm has developed a 75W laser diode for lidar in automated guided vehicles, service robots and robot vacuum cleaners. “In recent years, lidar is being increasingly adopted to precisely measure distance and for spatial recognition. For such markets, there is a need to improve the performance of laser diodes to increase detection distance and accuracy,” according to the company. The ...
Osram has announced a tiny projector that sprays 4,700 random dots into space to allow stereoscopic cameras to measure a 3D environment. Called Belago 1.1, it combines a 940nm VCSEL infra-red laser with a micro lens array, all in a 4.2 x 3.6 x 3.3mm package. The dots cover an angular field of 61° horizontally (FWHM) and 78° vertically . Non-periodic dot projectors ...
Efficient Power Conversion has introduced a 28A 1.2ns laser pulser demonstration and development board built around one if its GaN power transistors. The intended application is ‘time-of-flight’ range measurement, and the chosen GaN transitor (EPC2216 ) is AEC Q101-qualified, allowing the circuit to be used in automotive lidar projects. A novel aspect of this board is the ability to mount ...
Osram has released a green laser for phone-based projectors, capable of delivering 140mW pulses. Although a projector also needs red and blue lasers, green is the colour that poses the greatest challenges in semiconductor laser and LED production. “Up to now, RGB laser projections for smartphones, based on a red, green and blue laser, often had brightness problems,” according to ...
Schott has introduced a ‘TO’-style package to shrink actively-cooled 10Gbit/s laser diodes beyond what it claims is possible with box packages. “Box packages have a natural mechanical limitation in size reduction,” claimed Kenneth Tan, R&D manager at Schott Electronic Packaging in Singapore. “With TOs, the glass ceiling of miniaturization is broken.” Called Tec TO and based on the classic TO ...
