Measuring Embedded Objects

Philtec specializes in the design of fiber optic sensor systems for gaining access to 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 m)… 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

TORNOS Micro Introduced by EOT

EOT‘s new TORNOS Micro optical isolator is designed to be integrated inside a standard butterfly package diode laser for wide-ranging applications where optical feedback adversely affects performance. EOT’s isolators provide high transmission in the forward direction while strongly attenuating light traveling in the reverse direction, protecting lasers from the destructive effects of back reflections. The … Continue reading

Space Telescope Lens Tests

It’s not often we discover how well Philtec sensors perform for customers. The Euclid Satellite project is a good example of their sensors being used with excellent results in cryogenic conditions. A technical paper published in 2012  describes how Philtec’s high precision sensors were successfully used at 150°K to verify the distortion of lens holders to … Continue reading

New Technique Combining Expansion Microscopy and Lattice Light-Sheet Microscopy

A recent article in optics.org highlights the combination of expansion microscopy with lattice light-sheet microscopy. This new technique allows researchers to visualise spatial relationships between proteins across millimetre-scale dimensions. It counteracts many of the limitations of optical microscopy, electron microscopy, and super-resolution microscopy and is making incredible inroads into understanding the complexity of the brain. The research … Continue reading
