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.
Dan Ford walked us through some of what was on display for laser beam profiling and analysis applications before sharing information on Ophir’s high-power laser application initiative over the last year.
