Terahertz TDS: The Pulse Driving Industrial Innovation
Wed, May 28, 2025 10:00 AM - 11:00 AM EDT
Join us for an in-depth exploration of terahertz time-domain spectroscopy (terahertz TDS) and its transformative impact on industrial applications. This webinar will cover the fundamental principles of terahertz TDS while showcasing the latest advancements in Menlo Systems’ cutting-edge solutions, now featuring up to four times more terahertz power, 5× faster scanning, and improved detection capabilities with a dynamic range of up to 110 dB and a bandwidth of up to 6.5 THz. Through real-world case studies, it will be demonstrated how these advancements elevate quality control, material characterization, and nondestructive testing (NDT) across industries. Learn how terahertz TDS complements traditional NDT techniques such as near-infrared (NIR) spectroscopy, x-ray imaging, and ultrasonic testing — delivering deeper insights with unmatched precision and efficiency. Prince Bawuah, Ph.D., will explore practical applications in pharmaceutical manufacturing, semiconductor testing, coatings inspection, ceramics assessment, and electric vehicle battery electrode analysis, among others. Attendees will gain actionable insights into how terahertz TDS helps reduce operational costs, enhance product quality, and optimize industrial processes. Presented by Menlo Systems.

Practical Aberration Correction Using Freeform Optics — Pushing the Boundaries of Laser System Performance
Thu, Jun 12, 2025 10:00 AM - 11:00 AM EDT
Many laser systems — whether they are for industrial, biomedical, or defense applications — are designed to create a well-defined output spot or beam; this is required for the laser process to be as efficient, productive, and effective as possible. Optical aberrations in the laser system (pointing, defocus, spherical, astigmatic, coma, etc.) come from a variety of sources and affect the extent to which the actual output spot (or beam) deviates from that of the design intent of the system. To compensate for aberrations, it is vital to make appropriate measurements of the aberrations, and then ideally represent them as Zernike coefficients. Then, it is possible to design a freeform surface — using refractive principles — as a freeform aberration compensator. If the freeform surface can be designed and manufactured with a fast turnaround, the aberration compensator can be regarded as an “in-build” solution. By making the freeform in fused silica using a precision direct write laser machining process, it demonstrates the manufacture and testing of aberration compensators that have extremely low scatter and low loss. These fused silica freeform aberration compensators can therefore be used in either extreme high-power applications, e.g., laser inertial fusion, or extremely sensitive low-light applications, e.g., fluorescence microscopy and cytometry.
