Can anyone recommend an affordable spectroradiometer (model/brand) suitable for spectral hemispherical irradiance measurements in the UVA-Vis range?.
Ideally, a model "similar" to "Black comet" from "Stellarnet" ( http://www.shopstellarnet.com/black-comet-sr-concave-grating-fiber-optic-spectrometer/ ) is what I am looking for...or the "Green wave" ( http://www.shopstellarnet.com/low-cost-green-wave-spectrometer/ ).
I am aware that a lower price usually comes with a lower quality. However, for the time being, my budget requires me to find something around 500 - 1,500 USD.
