For Immediate Release

Coherent to Showcase a Broad Portfolio of Product and Technology Innovations at Photonics West and BiOS Expo 2024

January 25, 2024 Press Release


PITTSBURGH, Jan. 30, 2024 (GLOBE NEWSWIRE) – Coherent Corp. (NYSE: COHR), a global leader in materials, networking, and lasers, announced today that it will exhibit industry-leading products and capabilities at SPIE Photonics West, Jan. 30-Feb. 1 at the Moscone Center in San Francisco, Booth #4805 (Hall F), and at BiOS Expo Jan. 27-28, part of Photonics West, in Booth #8630 (Hall D). Coherent will showcase its broad portfolio of products and technology innovations that are enabling a wide range of applications in industrial, communications, electronics, and instrumentation markets. Coherent thought leaders will present at industry events, workshops, and technical sessions.



  • Dot projector module for depth sensing: This module enables customers to design cameras that capture an entire scene at a broad angle and extended depth range even in bright outdoor lighting conditions, all while maintaining low power consumption.
  • VCSEL-based illumination module platform: This platform uses eight 940 nm vertical-cavity surface-emitting laser (VCSEL) modules that allow selectively addressable horizontal slices of the field of illumination (FOI). A demonstrator is available to explore multiple VCSEL module positioning configurations and scanning algorithms for various depth sensing modalities and types of scenery.


  • OBIS 640 XT red laser module: This module matches the high output power, low noise, beam quality, and compact size of Coherent’s existing portfolio of blue and green laser modules, which as a complete set enable high-performance super-resolution microscopy (SRM) systems.


  • WaveShaper 1000A, 4000A and 500B: These test and measurement instruments, which can generate arbitrary filter shapes in attenuation and phase, are now available over a wider wavelength range extending into the U- and Super C-bands.


  • 532 nm HyperRapid NXT industrial picosecond laser: This laser, with its 100 W average output power, is ideal for ultraprecision manufacturing of thin-film solar cells. Other applications for this laser include structuring of battery foils and dicing of silicon wafers.
  • Infrared wire-grid polarizers (WGPs): This family of infrared polarizers operate in the MWIR over 3-5 µm and the LWIR over 7-14 µm, for laser-based atmospheric remote sensing applications. They are based on meta-optics wire technology that achieves a contrast ratio of an order of magnitude greater than the highest-performing comparable products in the industry.



Test and Measurement: WaveShaper 4000A/U-Band and WaveAnalyzer 400A (Booth #4805)
Coherent will demonstrate arbitrary optical filtering using the newly introduced WaveShaper 4000A/U-Band in combination with a WaveAnalyzer 400A High-Resolution Optical Spectrum Analyzer. With its broad wavelength coverage, the new WaveShaper 4000A/U-Band supports research and development activities in next-generation optical networks.
