Glen Spectra offer a
variety of Portable Spectroradiometers.
PR-655 and PR-670
are a fully portable hand held spectroradiometer for the visible
range. It can be configured to perform either spectral radiance
or spectral irradiance measurements over the 380 to 780nm range.
From these luminance (cd/m²) or illuminance (Lux) and colour
(x, y, u', v' etc.) can be calculated and displayed on the instrument.
The spectroscopic data can be saved to an on-board memory card for
later downloading to a computer.
has additional sensitivity and a greater variety of field of view
options than the related PR650. Again it can be used without a
computer, luminance/illuminance and colour information can be seen on
the instrument's own display and full spectral data can be stored on
board and downloaded when convenient. An optional battery pack is available.
is powered from a computer's USB port so can easily be used for
simple measurements in conjunction with a laptop.
