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 region. The 64-pixel height (0.89 mm) enables catching as many photons as possible while the cooling enables long integration times up to 120 seconds with low-noise levels. The instrument features 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 kinds of applications.
