VCSEL-specific spectrometers

Harald Sittenauer2023-07-13T10:31:02+02:00OtO Photonics is launching the Merak Series (MR) spectrometers, which adopt a transmission grating and a fully transmissive Czerny-Turner optical design to deliver high resolution, high sensitivity, low dispersion, and high-speed spectrum response. This series also features an improved integrated body and built-in LED indicators. It employs patented alignment mechanism to deliver optimum (0.1 nm) optical resolution to address the needs of high-resolution and high-sensitivity measurements. The MR series has a wavelength range of 830 - 970 nm, with a resolution <0.1 nm. Therefore, it is an ideal solution for VCSEL characterisation.  

Dubhe (DB) spectrometers for optical coherence tomography

Harald Sittenauer2023-07-13T10:31:47+02:00Dubhe (DB-series) spectrometers are designed for the high-resolution, high-sensitivity measurements required by optical coherence tomography (OCT). This new series features a transmissive optical design with an improved integrated body, employing patented alignment mechanism to deliver ultra-high (0.04 nm) optical resolution in the range from 800 - 880nm. It is available in two versions with different CMOS camera max line rates: 80 kHz or 20 kHz. The DB series uses a transmission grating and a fully transmissive Czerny-Turner optical design to deliver high optical resolution, high sensitivity, low dispersion, and high-speed spectrum response.

2 mJ ultrashort pulse laser FemtoYL for flexible materials processing

Harald Sittenauer2023-07-13T10:36:45+02:00YSL Photonics ps and fs lasers are used in solar cell production as well as in scientific applications. The new FemtoYL2-100 emits 6 ps to 400 fs short laser pulses at 1030 nm with a flexible repetition rate of 25 kHz to 5 MHz. The pulse energy of 300 µJ can be increased to 2 mJ in burst mode for precise micromachining.

125 W pulsed laser diode in SMD Package

Harald Sittenauer2023-07-13T10:38:45+02:00The Excelitas TPGAD series offers pulsed semiconductor lasers in a cost-effective SMD package that was specially developed for high-volume distance measurement and LiDAR applications. The output power of the 905 nm diode lasers is 18 W to 125 W - at a maximum pulse length of 100 ns and 0.1% duty cycle. Easy system integration is given by the compact size of only 2x2x3.5 mm. The mechanical design is further optimized for the integration of the lasers by providing high-precision reference surfaces for assembly.

New NUV-MT-series Si-photomultipliers offer leading PDE

Franz Schwarzbauer2023-07-13T10:42:03+02:00EQ Photonics shows the latest generation of UV-blue sensitive Si-photomultipliers - so called NUV-MT series - at the SENSOR+TEST in Nuremberg. These Broadcom devices allow customers to achieve best-in-class performance in their applications like, PET, radiation detection, high energy physics and astrophysics or flow cytometry. NUV-MT Si-photomultipliers offer industry leading PDE of 63%, low DCR, crosstalk and afterpulsing. The 2x2 mm, 4x4 mm and 6x6 mm devices show an excellent gain (7x10⁶) and gain stability (dG/dT ~ 1.5x10⁴). Various single pixels and array configurations are available in overmolded PCB packages. All parts are characterized by an exceptional degree of component uniformity.  

Doubling the PDE with the new NIR30-series Si-photomultipliers

Franz Schwarzbauer2023-07-13T10:43:27+02:00EQ Photonics is presenting the new Broadcom NIR30-series at the SENSOR+TEST in Nuremberg. These Si-photomultipliers particularly focuses on the detection of light in the red to near-infrared spectral range for applications in biophotonics, industrial distance measurements and analytics. Delivery of the SiPMs starts in the summer. Special highlights are the high PDE of 29% @ 905 nm, short recovery times of 16ns and a high dynamic range with over 6000 microcells per mm². The 1x1-mm Si-Photomultipliers come in a molded leadframe package and the linear 1x12(24) arrays in an automotive OQFN package. Both products are characterized by a high degree of component uniformity.  

Distance and motion 1D/3D Sensors

Franz Schwarzbauer2023-07-13T10:43:55+02:00EQ Photonics introduces Broadcom's AFBR-S50-series sensors for high speed and high accuracy distance and motion measurements. These time-of-flight modules uses highly sensitive 32 pixels detectors with various optics and laser configurations inside. With frame rates up to 3 kHz the AFBR-S50-sensors are fast tools to be used in robotics, autonomous mobile vehicles, drones and automation instruments. A video shows a typical application in a drone. They cover distances from ~0.01 to 50m and a field-of-view from ~0.4°x0.4° up to 12° x 6°. These time-of-flight sensors operate even under sunlight (100kLux) conditions. Easy system integration is given by a very compact size of approx. 12 x 8 x 8 mm, a simple 5V voltage supply and an integrated clock source . Data transfer is done via SPI.
