The Spero developed by Daylight Solutions is a purpose built fully integrated high spatial resolution high throughput Mid Infrared rapid imaging microscopy system. Spero incorporates Quantum Cascade Laser technologies and provides full frame, real-time imaging capabilities previously unavailable with bench top instrumentation.
Key Features
Some of the key features of Spero include::
- Real-time chemical imaging
- Rapid acquisition of full spectrum hyperspectral datacubes
- High-brightness, broadly tunable laser source
- Synchrotron class spatial resolution and sensitivity
- Specifically designed for mid-infrared spectral imaging analysis of materials research and biomedical samples
- Reflection and transmission modes of operation
- Fully automated stage
- Visible and infrared high N.A objectives
- Instrument control and data display via Ethernet to PC
- Turn-key small foot print integrated mid Infrared chemical imaging incorporating room temperature focal plane array
