The AvaSpec SensLine family of products is Avantes’ response to customers who require higher performance demanding spectroscopy applications such as fluorescence, luminescence, and Raman. The AvaSpec SensLine product line includes several high-sensitivity, low-noise spectrometers. Several of these instruments feature back-thinned detector technology, some of which feature our high-performance, thermoelectrically cooled detectors.
The other models feature standard CCDs, upgraded to high-performing instruments as a result of Avantes’ unique detector cooling technology. The back-thinned CCD detectors featured in the SensLine product family are high-quantum efficiency detectors with excellent response in the ultraviolet, visible, and near-infrared range from 200 to 1160 nm.
All AvaSpec SensLine instruments are fully integrated with Avantes’ modular platform, allowing them to function as both standalone and multi-channel instruments. These products are fully compatible with other AvaSpec devices in our AvaSpec SensLine and NIRLine. Every instrument in the AvaSpec SensLine is available as a lab instrument or an OEM module for integration into customers’ existing systems.
Avantes’ innovative ultra-low stray light (ULS), revolutionary high-sensitivity (HS), and the optimum compromise (HSC) optical benches are the core optical technologies in the AvaSpec SensLine. These highly stable optical benches, combined with our high-performance circuit boards, deliver high-performing instruments at affordable prices.
All members of the SensLine are designed to provide features such as:

The AvaSpec-HERO is the answer for those who are in need of high resolution and high sensitivity! This spectrometer combines the best of both worlds, so no compromise is needed.
The AvaSpec-HERO is built around our High-Sensitivity, Compact (HSC), 100mm optical bench offering a NA of 0.13 and a cooled, back-thinned detector (1024×58 pixels). Electronics-wise, it uses our latest AS7010 board, which includes a high-performance Analog to Digital converter with excellent noise performance and the ability of high-speed communication through USB 3.0 and Ethernet.
The combination of these two state-of-the-art components will give you an excellent instrument, offering the ideal balance between sensitivity and resolution and the capability of using longer integration times in low-light applications yet ensuring perfect signal-to-noise performance, transferred by the latest communication standards.
The Avaspec-HERO is suitable for use with replaceable slits, offering optimum flexibility for various applications. The combination of all the above features makes the AvaSpec-Hero your ideal companion for all your spectroscopic measurements.

The AvaSpec-ULS2048x64TEC-EVO is an updated version of our AvaSpec-ULS2048x64TEC spectrometer with improved electronics and cooling.
This instrument enhances the SensLine series with its cooled, back-thinned detector. The back-thinned detector has a high level of sensitivity in the UV and IR regions. The 64-pixel height (0.89 mm) enables catching as many photons as possible, while the cooling allows for long integration times of up to 120 seconds with low-noise levels.
The instrument features a Peltier cooling device integrated into our exclusive ultra-low stray-light optical bench, which can reduce the temperature of the CCD chip to -30°C against ambient, significantly improving the dark baseline and PRNU level. The detector cooling also reduces the dark noise by a factor of 2-3.
The AvaSpec-ULS2048x64TEC-EVO uses a special low-noise version of the 2048×64 detector with integrated cooling.
All the features mentioned above make this instrument ideally suited for measuring low-light applications, such as fluorescence or low-light Raman measurements.
Optimum flexibility is guaranteed with the replaceable slit, making the instrument suitable for various applications.

Alongside the cooled AvaSpec-ULS2048x64TEC-EVO with a low-noise detector, Avantes also offers the more cost-effective, uncooled AvaSpec-ULS2048x64-EVO. With its standard 2048×64 back-thinned detector, this spectrometer is perfect for less demanding applications in the UV and NIR ranges.
The cooling option is often unnecessary for applications that require integration times lower than 2 seconds. For example, this uncooled AvaSpec-ULS2048x64-EVO has an established track record in various DOAS applications worldwide because of its high UV response and 0.9mm detector height that enables detecting the wavelengths of interest.
Options include an order-sorting filter to reduce second-order effects and purge ports for deep-UV measurements. The AvaSpec-ULS2048x64-EVO comes with a wide range of slit sizes and gratings and can be configured with SMA or FC/PC fiber-optic entrance connectors.
The AvaSpec-ULS2048x64-EVO uses the AS-7010 electronics board offering USB3 (10 times faster than USB2), Gigabit Ethernet, and better signal processing.
Connection to your PC is handled via USB3 connection or Ethernet, delivering a scan every two milliseconds. The instrument comes complete with AvaSoft-Basic software, a USB cable, and an extensive manual.

Combining exceptional quantum efficiency with high-speed communication is the value proposition of the AvaSpec-ULS2048XL EVO spectrometer. Unlike many back-thinned CCD spectrometers with two-dimensional arrays, the ULS2048XL-EVO has large monolithic pixels of 14×500 microns with exceptional efficiency in the UV range, from 200 to 400 nm, and the NIR range, from 950 to 1160 nm.
The instrument also has an electronic shutter, which enables integration times as low as 2 microseconds. To further enhance sensitivity, a detector collection lens is available, which improves sensitivity up to 60% when combined with larger core fibers.

For high-sensitivity applications where high resolution is not of paramount concern, the AvaSpec-HS2048XL-EVO is an exceptional instrument.
Featuring Avantes’ HS optical bench, which has a full 0.22 numerical aperture for superior throughput, the AvaSpec-HS2048XL has a back-thinned CCD detector with 2048 pixels measuring 14×500 microns.
The AvaSpec-HS2048XL-EVO uses our AS-7010 electronics board offering USB3 (10 times faster than USB2), Gigabit Ethernet, and better signal processing.
