SUMMARY:ASME Turbo Expo 2026
DESCRIPTION:Join us in Booth # A69 at ASME’s Turbo Expo 2026 in Milan\, Italy\, June 16-18\, 2026 to learn about our latest optical\, non-contact\, and portable innovations in defect\, geometry\, and surface roughness measurement technologies. \nLearn how you can reduce scrap & rework and improve labor utilization & turn-around times with our industrial portfolio for aviation & aerospace engine manufacturing and MRO. \nWe will be showcasing our 3D area\, snapshot surface gauges\, including: \n\n4D InSpec – a handheld\, 3D surface gauge to quantify features and defects from 0.1 – 100mils deep instantaneously\, with a measurement area of 0.3in x 0.3in.\n4D InSpec XL – a 3D surface defect gauge with an expanded measurement area – 0.6in x 0.6in.\n4Di InSpec SR – the industry’s first portable\, nm-level resolution surface roughness system for precision machined surfaces\, enabling high-resolution 3D (aerial) roughness on large and small samples\, right on the floor or in the field.\n4Di InSpec AMS – a fully automated 3D\, optical inspection system with a collaborative robot to measure features such as chamfer\, radius\, and edge break\, and defects such as pits\, dings\, corrosion and scratches.

SUMMARY:SPIE Astronomical Telescopes + Instrumentation 2026
DESCRIPTION:Join us in Copenhagen\, Denmark\, July 7-9 to see our latest optical interferometer innovations! \nStop by booth #219 where we will be showcasing our PhaseCam and NanoCam; and bring your samples by to get measurements right on the show floor!  Learn about 4D Technology’s extensive product portfolio\, including: \n\n\n\nAccuFiz Fizeau interferometers: Compact\, high-performance Fizeau interferometers for shop-wide optics measurement at visible to SWIR wavelengths.\nAccuFiz D and Duo interferometers: short coherence Fizeau interferometers for measuring thin\, transparent\, plane-parallel surfaces < 0.2mm apart without the need for coating.\nPhaseCam: vibration-immune Twyman-Green interferometer with high power for measuring large optics and systems\, and for long measurement paths. Its super-fast single-frame data acquisition enables measurement despite vibration and turbulence\nIR Systems:  Measure at wavelength with our PhaseCam and AccuFiz IR systems.  NIR – SWIR – MWIR – LWIR\nNanoCam HD: a small\, non-contact optical profiler for vibration-immune roughness measurement in challenging conditions\n\n \n\n
