Spectral measurement of a Comb with 20 MHz repetition frequency made by the APEX Technologies High Resolution Optical Spectrum Analyser This paper is devoted to present the capacity of the Apex Technologies High Resolution Optical Spectrum Analyser/Optical Complex Spectrum Analyser to show clearly all the Optical Comb sidebands even with a few tens of MHz spacing. Two commercial Optical Frequency...

High return loss in a network or data centre is an issue that can cause a number of problems ranging from source stability to increased BER and a lower signal-to-noise ratio. As a result, pass/fail criteria on fibre optic connections has jumped in recent years as advancements in polishing techniques have allowed for fibre optic matings with lower reflections. Click...

The new industrial cameras of the Baumer EX series focus on essential standard-compliant basic functions and therefore are ideal for varied typical machine vision applications. Integrating the latest generation of CMOS sensors in their robust metal housing, they provide long-term stability in application designs. With resolutions from VGA up to 2 megapixel and up to 217 frames per second, the...

A frequency response analyser is a piece of test equipment designed to inject a sinewave into a circuit, and measure the frequency response of the circuit at multiple test points in order to generate a gain and phase response. This application provides Frequency Response Analysis (FRA) capabilities for the PicoScope instruments from Pico Technology. The FRA uses a common technique...

Metricon’s prism coupling instruments have been referenced in numerous scientific journal articles spanning a wide range of disciplines. This list of Journal References on the prism coupling technique is divided into the following categories: An initial short section entitled "Basic Theory of Prism Coupling" lists representative articles on the theory of thin film waveguides and the prism coupling technique. To...

Metricon’s Model 2010/M offers important advantages over ellipsometry for many applications - unmatched refractive index accuracy, dramatically simpler operation and data analysis, and greater tolerance of poor sample quality. Although prism couplers and ellipsometers can both be used to measure the index of bulk materials and to simultaneously measure film thickness and refractive index, there are major differences in the...

The Metricon Model 2010/M prism coupler offers unmatched ease and accuracy in measuring: Refractive index/birefringence of bulk materials Refractive index and thickness of thin films Loss of optical waveguides Compared to instruments based on optical interference, ellipsometry, or Abbe refractometry, the Metricon 2010/M’s prism coupling technology provides unmatched index accuracy/resolution, and minimal sample preparation is required. The system also measures...

The Model 2010/M can be used to measure thickness and index for one or both films of a dual film structure (as many as four film parameters) provided the top film has a higher refractive index than the lower film. Dual film measurements on transparent substrates or underlying (third layer) films are even possible in many cases. Detailed specifications for...
