Background An axial-flow pump (AFP) is a common type of pump that essentially consists of a propeller (an axial impeller) in a pipe. Cryogenic turbopumps (CTP) are the heart of a rocket engine. With today’s generation of reusable heavy launch space vehicles, CTPs supply pressurized subcooled fuel and oxidizer fluids, which mix and ignite to … Continue reading
Sumix Corporation announces its collaboration in support of the introduction and implementation of the new 3M™ Expanded Beam Optical Connector. Sumix developed and introduced a new adapter for the industry leading Manta-W+ fiber inspection microscope to effectively inspect and test the new connector end face. The 3M™ Expanded Beam Optical Connector is based on a … Continue reading
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
Total Thickness variation (TTV), and often wedge, is a specification of optical windows and substrates. There are two methods for measuring TTV: Front-to-Back (left image above) and Direct (right image above). Both methods utilize Fizeau interferometers, a product line of Äpre Instruments. Front-to-Back Measurement TTV can only be calculated if the front and back … Continue reading
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‘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
