Acousto-Optic Beam Modulators and Deflectors Control Laser Beams in Many Applications. by John Lekavich, Director, IntraAction Acousto-Optics, the interaction of sound waves and light in a transparent medium, has proven an effective means of amplitude-modulating, deflecting, or shifting the optical frequency of laser light. When a transparent medium is subject to a stress, the optical refractive index of the medium...

Never Miss a Signal Today’s RF designs utilise rapidly changing and pulsing signals that are difficult to consistently capture on traditional swept spectrum analysers. The Rigol RSA5000 delivers a class leading 7.45µsec 100% probability of intercept meaning that any pulse with a duration of greater than 7.45µsec will be captured and accurately displayed. Isolate & Capture IoT Device proliferation means...

The Ultra High Resolution OSA (UHR-OSA) proposed by APEX Technologies remains a very important tool not only to measure the optical OFDM (Orthogonal Frequency Division Multiplexing) signal spectrums even with few tens of MHz spacing sub-carriers but also to adjust and adapt it to other modulation techniques. APEX-UHR-OSA incessant need in OFDM research area APEX UHR-OSAs have found a wide industrial and...

The APEX Technologies Ultra High Resolution Optical Spectrum Analyser (OSA) can be used to measure the active/passive optical component insertion loss/gain thanks to the possibility to synchronise the internal Tunable Laser Source and the OSA sweepings. In this context, the APEX OSA remains a perfect tool to measure the Fibre Bragg Grating (FBG) Sensor reflection with 1 MHz of resolution...

For 30+ years Lambda Photometrics have represented Stanford Research Systems (SRS) in the UK as SRS’s authorised UK distributor and service centre with unparalleled experience of supporting their products. To ensure best value for money some companies require several quotes to satisfy their organisation’s purchasing policy. In order to clarify any confusion over comparisons between Lambda’s pricing and SRS’s International...

An absolute position measurement system has a noise floor of less than 0.02 nm/√Hz over a range of 1.2 mm. Measuring to the nanometer scale is no small feat—getting there takes careful engineering and a fundamentally good sensor. The sensors used for stage position feedback inside semiconductor lithography tools regularly achieve this level of precision. Zygo has supplied displacement measuring...
