2.5 – 5 µm Mid IR Spectrometers

The MIRS Series Spectrometer, based on TE-cooled PbSe detectors, is optimized for MIRS spectroscopic measurements requiring an exceptional signal-to-noise ratio and high dynamic range across the 2.5 – 3 µm spectral range. This system leverages innovative, patent-pending scanning technology, offering significant advantages: 1) Unmatched low cost; 2) Industry-leading sensitivity with deep cooling to -40 °C; 3) Extended spectral coverage beyond traditional spectrometers; 4) Low power consumption; 5) Integrated MEMS chopper; 6) High resolution performance. Additional features include photon integration for low-noise detection and connectivity via USB or RS232 with an intuitive GUI. The MIRS series is available in both OEM modules and turn-key units with integrated power supplies.

Integration and compatibility

Use these checks to connect 2.5 – 5 µm Mid IR Spectrometers to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.

Optical interface and fiber: Connector: SMA905, FC/PC, SC/PC, ST/PC, Special; Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
Wavelength and loss budget: Wavelength: 2.5 - 5μm; Check the Spectrometers passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.

Technical FAQ

Integration questions for 2.5 – 5 µm Mid IR Spectrometers

Which fiber and connector does the 2.5 – 5 µm Mid IR Spectrometers use?

Connector: SMA905, FC/PC, SC/PC, ST/PC, Special. Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.

How should the 2.5 – 5 µm Mid IR Spectrometers be included in an optical power budget?

Wavelength: 2.5 - 5μm. Check the Spectrometers passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
