Ultra-compact design without sacrificing performance

Ibsen Photonics EAGLE C-OCT-S-90 is a high-performance, compact 90 nm OCT spectrometer, built around our high-speed M-DISB-191 electronics platform with the Hamamatsu S17122 CMOS sensor.

With 90 nm bandwidth across a 2048 pixel detector, the spectrometer is capable of measuring depths up to 4 mm (in air) with an axial resolution down to 4.1 µm (in air). Its ultra compact form factor, measuring just 130 x 75 x 36 mm3 and weighing only 600 grams, is enabled by innovative optical engineering and the optimized footprint of the M-DISB-191 electronics.

Despite its compact size, the EAGLE C-OCT-S-90 delivers the same exceptional optical performance as industry-standard OCT spectrometers equipped with 10 µm pitch cameras. Its diffraction-limited design ensures a compact form factor without any compromise to roll-off performance.

It is further enhanced by the M-DISB’s MIPI interface, which provides a near-hardware, low-latency connection that eliminates the need for costly frame grabber cards or the overhead of a USB connection. This allows for direct interfacing with image signal processors, resulting in a cost-optimized, high-performance system ideal for large-volume production.

Key benefits

  • High optical throughput

M-DISB-191 electronics

The EAGLE C-OCT-S-90 features Ibsen’s in-house developed M-DISB electronics, paired with the Hamamatsu S17122 CMOS detector. This combination delivers line rates of 61 kHz for all 2048 pixels in a 12-bit data format, and 101 kHz when using pixel binning or a region-of-interest (ROI) reduced to 1024 pixels (and 2 mm measurement depth).

The M-DISB-191 electronics utilizes the MIPI-CSI2 data transfer protocol, (with a USB3 Developer Kit available) and offers an extensive range of advanced features.

Key features

  • 12-bit 2048 pixel detector

  • Line-rates of up to 61 kHz for 2048 pixels and 101 kHz for 1024 pixels.

  • Configurable well depth

  • Internal trig generator

  • External trigger for HSYNC/VSYNC

  • MIPI CSI-2 data connection, with USB development board available upon request

Benefits of transmission grating based spectrometers

The EAGLE is a series of high-resolution spectrometers. This is obtained by a unique lens-grating-lens design utilizing Ibsen Photonics’ high dispersion transmission gratings. Furthermore, the spectrometers provide high efficiency and high throughput.
