Thermo-Electric Cooled Fiber Optic Spectrometers: AvaSpec- ULS TEC Datasheet

The AvaSpec-ULS TEC can be delivered with 2 different TE cooled detector arrays with (2048L / 3648 pixels) as 1- or 2-channel instrument and has all the standard options, gratings and specifications the standard AvaSpec has. The AvaSpec- ULS TEC Thermo-Electric Cooled Fiber Optic Spectrometers are ideal for low light-level applications, such as fluorescence and Raman measurements, where integration times of more than 5 seconds are needed.

AvaSpec-ULS TEC Features:

• Newly designed three-stage Peltier cooling device reduces the CCD chip temperature by -35 °C
• Ultra low stray light optical bench
• Size of the ULS-TEC is reduced more than 35% versus the previous TEC spectrometers
• Newly designed housing
• Integrated temperature regulator
• USB2 high speed interface
• 2 cooling fans actively ventilate the heat sink of the Peltier cooling elements
• Internal power supply

AvaSpec-ULS TEC Benefits:

• Ultra low stray light
• Dark noise is reduced by a factor of 2-3
• Improved dark baseline and PRNU level
