Our I-MON Interrogation Monitor series for Fiber Bragg sensing systems consists of the following popular variants: OEM – Our successful I-MON 256 OEM and its big brother, the I-MON 512 OEM with broader wavelength version. You make the electrical interface, and the pin-compatible diode arrays allow you to drive both versions with the same electronics. USB – We make the electronics interface and pack the devices in a rugged EMC shielded housing, as we did with the well-proven I-MON 512E. This relatively new and cost-efficient series includes the I-MON 256 USB and the I-MON 512 USB. Measurement speed up to

Absorbance spectroscopy is a molecular spectroscopy method that uses the wavelength-dependent absorption characteristics of materials to identify and quantify specific substances. Many molecules absorb ultraviolet or visible light emitted from a broadband light source. The absorbance is related to the concentration of the materials in the sample such that stronger absorbance means higher concentration. There are many different approaches for measuring absorption spectra. The most common one is to point a generated beam of light at a sample and detect the intensity of the radiation that goes through it. The energy that is then transmitted is used to calculate the

[h2]Digital Micromirror Device[/h2] Fiber Bragg gratings (FBGs) have become more and more attractive in recent years because they are small, cost effective, easy to manufacture and insensitive to electro-magnetic interference. The basic principle of FBG sensing is to measure the reflected spectrum and to track the FBG peak positions. Due to the availability of low-cost tele-communications equipment, the most common and commercially available FBGs work in the 1550 nm range. However, this requires use of expensive 1550 nm InGaAs array detectors to interrogate the sensors. In this newsletter, we present a novel type of multichannel MEMS based spectrometer, where the linear
