Switchable LED Light Source contains 10 high power LEDs placed on a revolving disc. The user switches between a selection of monochromatic LED sources and white LED using an application software. It enables controlling also light intensity, duration and a couple of the other parameters. A manually adjustable lens is used to focus light on a sample installed in a photo-electrochemical cell (cell is not included in the setup). The LED disc is exchangeable, which means that the user can order a disc with custom LEDs, separately.

Compared to conventional light sources such as halogen and gas discharge lamps, this Switchable LED Light Source offers many advantages such as:
higher signal-to-noise ratios (due to narrow bandwidth emission),
better stability,
longer life (LEDs are operated below their maximum power level),
lower replacement costs,
no active cooling requirements,
no thermal filters in the optical path,
smaller dimensions, etc.

Application note

Switchable LED Light Source is a universal light source for general lab use and OEM applications. It can be used wherever a strong monochromatic LED light is needed. In photo-electrochemistry it is often used as an economy light source for fast screening of photo-catalytic thin films, as well as the broad range of standard photoelectrochemical experiments. It is a versatile light source with LED switching and accurate intensity modulation of each individual LED. The device is compatible with the cages from Thorlabs and TECHSPEC from Edmund Optics.
