Company Andor has introduced the new Kymera 328i spectrograph, replacing the popular Shamrock 303i spectrograph.

Technical improvements have been implemented in the new spectrograph, making it a versatile and flexible high-resolution instrument.

Key features:

Adaptive Focus

The patented Adaptive Focus technology automatically ensures optimal focusing of the spectrograph, allowing the best resolution for all wavelengths. This ensures automatic optimization when changing gratings or detector .

TruResTM

Technology that allows you to increase spectral resolution when needed. This is a purely optical method without the use of mathematical algorithms such as deconvolution etc.

Four-position grating tower

  • The grating tower has capacity for up to 4 gratings providing great flexibility for a wide range of applications.

  • The rotation of the individual grids takes place in an 'on axis' arrangement. This results in improved performance even for large grid set angles

  • The tower is equipped witheXpressIDTM RFID technology for automatic grid recognition and parameter upload to the spectrograph

Other key parameters

  • Astigmatism-corrected optical design

  • Possibility of combining two outputs and two inputs

  • integrated drivers in the μ-Manager software. Possibility to use as a spectrograph for micro spectroscopy
