Developer’s Kit

The FREEDOM VIS-NIR is offered with a Developer’s kit for a plug and play experience.

The Developer’s Kit allows you to easily demonstrate the performance of the spectrometer without the need for complex hardware integration or time-consuming programming.

Benefits of transmission grating based spectrometers

The FREEDOM is a series of versatile spectrometers. This is obtained by a unique mirror-grating-mirror design utilizing Ibsen Photonics’ high dispersion transmission gratings. Furthermore, the spectrometers provide high efficiency and high throughput, together with high resolution and a broad wavelength range.
