In this video, Mad City Labs SPM Etch kits are utilized to create tungsten tips for atomic force microscopy (AFM). The kit permits the user to attach a wire to a quartz tuning fork and electrochemically etch the wire to a fine tip.
The Woodward company is one of the oldest U.S. companies that started out providing water wheel governors and has grown to delivering control systems for reciprocating engines, gas steam engines, aircraft turbines, and aircraft actuation flight control. As these systems become more advanced, they must be regulated at higher standards. Woodward uses ZYGO’s optical metrology technologies to advance their materials inspection.
Celebrating their 50-year anniversary as a company that offers precision optics and optical metrology technologies, ZYGO is excited to present once again at Photonics West 2020. Check out the video to see their featured products, including optical profilers, and learn more about their precision optics manufacturing capabilities.
Measuring very low power beams of light can be tricky; even small values of noise, drift or offset can have major impact on your readings. In this video, we’ll look at some best practices that can help you get the best performance from your very low power measurements.
At Photonics West 2017, Greg Staples focused on selecting different wavelengths for specific applications. Watch the video for wavelength selection guidance for precision agriculture, food sorting, mining, pharmaceutical quality control, and more.
This year at Photonics West, Erin McDonnel and Eric Felkel with Zygo gave us a glimpse into how their interferometers can be used to perform accurate surface metrology in adverse environments (like a trade show floor).
Eric Craven with Ophir Photonics provided us with a tutorial at DCS 2016 on how to co-align visible, near-infrared, and infrared laser beams through the use of a pyroelectric camera array coupled with beam profiling software.
Hyperspectral imaging technology has advanced significantly in the last 50 years, and Greg Staples with Bayspec talked with us for a few minutes at the 2016 SPIE DCS exhibition about how it has changed.
At Zygo' booth this year, Tyler Steele introduced us to the Verifire™ series of interferometers for the measurement of plano, spherical and aspherical surfaces and material characteristics. He then turned it over to Eric Felkel who showed us the Nomad™, a portable optical profiler for measuring topography and roughness on optical surfaces.
