Photorelay is suitable for factory automation
Toshiba Electronics Europe has released the TLP3122A photorelay for factory automation and other industrial applications including building automation, security and semiconductor testing. The photorelay integrates MOSFET devices fabricated using the latest U-MOS IX process to reduce on-state resistance. Housed in the small 4-pin SO6 package, the TLP3122A provides an off-state output terminal voltage (VOFF) of 60V, a constant on-state current...
Narrow bandpass filters suitable for demanding LiDAR
In response to increasing demand for flat-top narrow bands for laser applications, Laser Components has announced an addition to its range of optical filters. The series of 4-cavity Fabry-Perot narrowband filters is suitable for demanding LiDAR, range-finding and free space optical communications applications. The filter coatings are fabricated from hard oxide materials so as to minimise wavelength shift due to temperature and angle of incid...
Expanding the portfolio of linear Si APD arrays
The LASER COMPONENTS Detector Group has expanded its standard range of linear Si APD arrays in LCC44 housings containing 8 and 16 elements. The SMD components can be mounted on circuit boards, while also providing enough space for the integrated multi-channel amplifier circuit. Their operation only requires the voltage for the array and 5V for the electronics. The arrays comprise of a monolithic series of fast, low-noise avalanche photodiode...
LED holders compatible with COB-LED lighting components
TE Connectivity has added the LUMAWISE Z45 LED Holder to its range of holders for chip-on-board (COB) LEDs. The second-generation LED holder from TE is made in a high-strength, highly reflective halogen-free flame retardant thermoplastic (PBT). The Z45 LED holder is 5mm smaller in diameter compared to TE’s Z50 holder and uses adhesive for fast and easy assembly of the COB LEDs in the luminaire.
Single carrier wireless link travels at 100Gb/s data rate
A single carrier wireless link travelling at a 100 Gb/s data rate has been demonstrated by Tektronix and IEMN, a major French research laboratory. This demonstration uses advanced data coding, THz photonics and wideband and linear devices to enable ultra-fast wireless connections in the 252 - 325GHz band per the recently published IEEE 802.15.3d standard.
TLC optics eliminates the wait for thermal stability
For high power laser applications, thermal lensing can be an issue. Focal length can vary with running time as a result of heat build-up in optics due to power throughput. The TLC, or Thermal Lensing Compensation optic design from Haas Laser Technologies, passively compensates for thermal lensing for high power collimators and focal lenses. Thermal lensing for lasers with powers in excess of 1kW is reduced to less than the Ray...
Powerful UVB LEDs for fluorescence microscopy
LG Innotek has increased the performance of its UV LEDs. At the UVB wavelength of 305nm, LASER COMPONENTS has offered LEDs that achieve 110mW from a single emitter. They are used in the 6060 single-chip series as well as the 6868 series, which features four diodes integrated into one housing. Together they deliver outputs of 300mW and more. LEDs with the same power levels are also available for the UVC wavelength 278nm.
IBS mirror coatings in the wavelength range 248nm to 3000nm
LASER COMPONENTS now has Ion Assisted Deposition (IAD) and Ion Beam Sputtering (IBS) coating capabilities. Being a precise and replicable method, IBS coatings are used for the most spectrally demanding applications, such as steep edge dichroic mirrors and very broad band mirrors. Unlike other coating technologies, process parameters such as beam energy, layer growth rate and oxidation level, can be individually regulated ...
Making buildings shine with a swipe on your smartphone
Philips Lighting has announced the launch of a cloud-based Scene management app that enables businesses to change a building's architectural lighting using your smartphone or tablet. The app is designed for use on smart devices. With a simple tap or swipe, the Interact Landmark Scene management app enables lighting managers to manage, control and change the lighting on bridges, buildings and monuments on the fly.
The use of pyroelectric detectors for non-contact temperature
Every object emits heat in the form electromagnetic waves and sampling the energy radiated into space allows the measurement of the temperature of the object without ever having to touch it. The wavelength of the light emitted by the object depends on its temperature, with hotter objects generating light at shorter wavelengths. Thermal detectors have the widest wavelength response with the limiting factor being the transmission window used to pro...
