EAGLE OCT-S-M-90

Home / Products / OEM Spectrometers / OCT

High performance and form-factor optimized

The EAGLE OCT-S-M-90 is a spectrometer based on the EAGLE OCT-S-90, delivering the same exceptional optical performance in folded and a more compact, optimized form factor. Just like the OCT-S-90, the OCT-S-M-90 is ideal for high-performance OCT spectroscopy, offering an axial resolution down to 4.1 μm (in air) and depth measurements down to 4 mm (in air), with uncompromised roll-off.

At the core of this OCT spectrometer is Ibsen Photonics’ fused silica transmission grating, which delivers the highest diffraction efficiency available in the OCT market. This enables the spectrometer to achieve exceptional sensitivity for Optical Coherence Tomography (OCT) performance.

Key benefits
