Measuring Embedded Objects

PHILTEC specializes in the design of fiber optic sensor systems for measuring embedded objects in hard-to-reach targets. In March 2019, several dozen model D47 sensors were delivered with long fiber optic cables and very small 90° probes as seen here. The fiber optic cable lengths varied from 21 ft (6.4 m) to 55 ft (16.8 … Continue reading

Using Ultrafast Laser in FT-CARS

A published paper by Hashimoto et al. (2018), entitled “Ultra-Broadband Rapid-Scan Fourier-Transform CARS Spectroscopy with Sub-10-fs Optical Pulses”, leverages the benefits of products from Novanta. The experimental set-up contains a venteon ultra oscillator from Laser Quantum. The paper demonstrates ultra-broadband Fourier-Transform Coherent Anti-Stokes Raman Scattering (FT-CARS) spectroscopy. The technique spanned over 3000 cm-1, particularly useful … Continue reading

EOT Introduces TORNOS Micro Optical Isolator

EOT‘s new TORNOS Micro optical isolator works inside a standard butterfly package diode laser for wide-ranging applications. This configuration reduces the optical feedback that adversely affects performance. EOT’s isolators provide high transmission in the forward direction, while strongly attenuating light traveling in the reverse direction. This feature protects the laser from the destructive effects of … Continue reading
