AVANTES SPECTROMETER DRIVER

The low cost, modularity, flexibility and speed of measurement made possible by fiber-optic spectrometers have resulted in wide adoption of this technology in a variety of industries. If your application does not require the highest possible resolution and is not one that has an excess of light laser measurement for example , we recommend that you consider as large a slit as possible to maximize throughput into the optical bench. Your business OEM Avantes has over 22 years of experience in applying spectroscopy and optical sensing technologies to enumerable environments and industries. It is important to balance your need for resolution with the need for sensitivity and throughput into the optical bench. The easy coupling of fibers allows a modular build-up of a system that consists of light source, sampling accessories and fiber-optic spectrometer. This line provides leading-edge performance for dispersive NIR instruments with toroidal focusing mirrors and dynamic dark correction for enhanced stability. For laboratory, research institutes and universities we offer a great variety of spectroscopy products.

A silicon photodiode array consists of a linear array of multiple photo-diode elements, for the AvaSpec this is pixels. The AvaSpec instrument line is divided into three groups based upon general requirements. Our instrument line offers a wide selection of detectors and gratings to provide a multitude of configurations.

Our unique modular instrument architecture enables a multi-channel platform, offering customers the flexibility to configure up to ten spectrometers in a single enclosure. Each bundle contains all products you need to get started with your soectrometer.

This section provides you some guidance on how to choose the right grating, slit, detector and other configuration options, to be installed in your AvaSpec. Avantes offers full traceability on following detector specifications: Ambient light Scattering light from imperfect optical components, or reflections of non-optical components Order overlap Avantes symmetrical Czerny-Turner optical bench designs favor stray-light rejection relative to crossed designs.

AvaSpec-ULS High-resolution Spectrometer – Avantes

Our unique modular instrument architecture enables a multi-channel platform, offering customers the flexibility to configure up to ten spectrometers in a single enclosure. Thanks to the need for fiber-optics in the communication technology, low absorption silica fibers have been developed. In the next table the specification is given for the NIR spectrometers, followed by the xpectrometer response curve for the different detector types are depicted.

The filter types that are 3 mm thick give much better 2nd order reduction than the 1 mm filters. Please contact our application engineers to optimize and fine-tune the system to your needs.

spectromteer This effectively reduces the width of the light beam entering the spectrometer optical bench. The AvaSpec fiber optic spectrometer can be delivered with 2 platforms of electronics; either with USB1. The strategy is to limit the light to the region of the spectra, where order overlap is not possible. See the NIRLine instruments productline. If resolution is optimized without considering the need for throughput, you may not have adequate light to get a stable measurement.

Fiber Optic Spectrometer: AvaSpec – Avantes BV

New is the AvaSpec-RS with replaceable slit that makes your spectrometer a versatile instrument for both high-resolution and high-sensitivity measurements. The low cost, modularity, flexibility and speed of measurement made possible by fiber-optic spectrometers have resulted in wide spectrmoeter of this technology in a variety of industries. These same CCD and PDA detectors are now used in the Avantes AvaSpec line of spectrometers, enabling fast scanning of the spectrum, without the need for a moving grating.

Options include order-sorting filters to prevent 2nd order effects, deep-UV detector coating for better sensitivity in the deep-UV-range, and a detector collection lens to enhance overall sensitivity. This line provides leading-edge performance for dispersive NIR instruments with toroidal focusing mirrors and dynamic dark correction for enhanced stability.

CCD detectors are naturally integrating and therefore have enormous dynamic range, only limited by the dark thermal current and the speed of the AD converter. Peak wavelength and QE peak The peak wavelength is provided by the detector supplier as well as the Quantum Efficiency, defined as the number of electrons generated by one photon.

Table 2 illustrates how to read the grating spectromdter table.

In addition to the order-sorting coatings, we apply partial DUV coatings on the Sony detectors to spectfometer second-order effects from UV response and to enhance sensitivity and decrease noise in the visible range.

Full Width Half Maximum During avanyes thermal cycling the average FWHM value is measured and has to fit with a certain standard deviation within the QC acceptance norm as can be found in this catalog for the different configurations. In a monochromator system there is normally also an exit slit, and only a narrow portion of the spectrum is projected on a one-element detector.

Temperature sensitivity on the intensity axis can have a number of reasons. Each bundle contains all products you need to get started with your measurement. The slit image on the detector array for a given wavelength will cover a number of pixels. Our instrument line offers a wide selection of detectors and gratings to provide a multitude of configurations.
