HELIOS FIRE is the next generation, automated femtosecond Transient Absorption Spectrometer in the HELIOS family. Among its numerous advantages, HELIOS FIRE features a 100-fold boost in sensitivity, allowing the study of more delicate samples. This, together with our patent-pending automated beam alignment system, delivers a new level of performance and user-friendliness. In addition to being virtually hands-off, HELIOS FIRE allows for user customization with its easily removable side panels and improved optical layout.

1 Enhanced sensitivity – compatible with nJ pump energy levels
2 Enhanced beam pointing – drift of <10 µm over the whole delay range
3 Unprecedented degree of automation:
- Automated optical delay line alignment (Smart Delay Line^TM)
- Automated pump beam alignment
- Automated switching between UV, VIS and NIR spectral ranges
4 More space around the sample – 225 mm x 250 mm
5 Parabolic reflectors for continuum management ensure uniform focusing of all wavelengths.

1 Fully Automated Optical Delay Line
- Time window: 8 ns
- Resolution: 14 fs
- Minimum step size: 2.8 fs
- Max. speed: >10 ns/s
- Acceleration: > 260 ns/s^2
- Automated alignment time: 3-5 min
- Beam pointing drift: <10 µm over 8 ns delay range
- Located inside the spectrometer housing
2 Fully Automated Pump Beam Alignment. The HELIOS FIRE software ensures continuous optimal overlap of the pump and probe beams in a sample with <10 µm precision.
3 Temporal Resolution. The instrument response function is a cross-correlation of the pump and probe pulses. See the optical delay line description for more details.
