A method of identifying the material and determining the physical thickness of each layer in a multilayer structure is disclosed.The method includes measuring the optical thickness of each of the layers of the multilayer object as a function of wavelength of a light source and calculating a normalized group index of refraction dispersion curve for…
One of our TOPTICA founders, Dr. Wilhelm Kaenders was recognized during this year’s BiOS/Photonics West 2020 for his contributions to the laser world and the company’s community engagement with the SPIE Fellow award. David Andrews, President-Elect of SPIE (left), and John Greivenkamp, President of SPIE (right), presented the award to Wilhelm. "Our Fellows represent the…
A new tip-tilt mechanism based on low voltage piezoelectric actuators has been designed by Cedrat Technologies (CTEC) to answer the need of a Point Ahead Mechanism (PAM) for the JPL Deep Space Optical Communication (DSOC) module of incoming Psyche mission. The PAM aims at deviating optical downlink signal towards earth position during DSOC communication phases….
The use of real macro water channels allows to maintain a high optical efficiency when talking about actively cooled Diode Laser Stacks making them cost-efficient in terms of performance and maintenance. Our ENCAST Series consists of laser diodes mounted with our exclusive ClampingTM technology. The solder-free clamping of laser bars is a revolutionary technique which optimizes diode…
Today’s best optical clocks achieve an amazing accuracy and would be off by less than one second over the age of the universe. These clocks rely on probing optical transitions in cold atoms with very stable and narrow linewidth laser light. The probed atoms provide the long-term stability and accuracy of the clock. Frequency combs…
The new Alvium 1500 C-210 offers resolution of 2.1 MP and thus fills the gap between the 1.2 MP Alvium C-120 and the 5 MP Alvium C-500. The camera combines a Full HD resolution with high frame rates (up to 118 fps!). Available at an attractive price, the 1500 C-210 offers a very good price-performance…
Laser welding is quickly becoming the preferred welding method in many industrial projects. However, while this technique offers numerous benefits over conventional welding, its performance depends heavily on the power characteristics of the laser beam. Unfortunately, laser beam power can fluctuate over time, resulting in inconsistent and potential dangerous welds. This is where regular maintenance and expert calibration comes…
The CELESTA light engine delivers approximately 1 watt of output power at the distal end of a 1.5 mm dia optical fiber from each of its 7 individually addressable multimode laser light sources. The laser outputs are allied to sophisticated control and monitoring systems to deliver the performance needed for spinning disk confocal microscopy, optogenetics…
The T210 is a small dimension high sensitivity sensor designed for monitoring cracks and vibrations in surface mounted applications. The T210 optical sensor consists of a Fiber Bragg Grating (FBG) sensing element embedded in a curved steel frame. This patented sensor yields excellent wavelength to crack growth linearity and its fast response time also makes…
