ASD - HandHeld 2 Pro: VNIR Hand-held Spectroradiometer

The FieldSpec HandHeld 2 Pro hand-held spectroradiometer offers greater sensitivity over the standard HandHeld 2 spectroradiometer model, aiding spectral measurements for applications with low reflectance characteristics such as water surfaces.

The FieldSpec HandHeld 2 Pro hand-held spectroradiometer offers greater sensitivity over the standard HandHeld 2 spectroradiometer model, aiding spectral measurements for applications with low reflectance characteristics such as water surfaces. Wherever there is a need for enhanced sensitivity, faster collection rates, high signal to noise performance, the HandHeld 2 Pro is the low cost VNIR spectroradiometer of choice.


The HandHeld 2 Pro spectroradiometer incorporates a 512-element photo-diode array with an area five times larger than the standard HandHeld 2, resulting in higher sensitivity. The larger photo-diode array elements allow for scan rates three times quicker and provides a five times improvement in the signal-to-noise ratio when compared to the standard HandHeld 2 model.
