LED 白光光源 LED Light Source for Easy Fluorescence Imaging

作者: Kevin Peng    发布于: 2015-03-24 16:18    点击:

The wLS broad-band LED illumination unit is designed to provide a long-life alternative to traditional Mercury and Mercury Metal Halide fluorescence excitation sources. The broadband excitation covers common fluorophores, ranging from DAPI to Cy5, allowing existing filter cubes and protocols to remain in place. Unlike other broad-band LED solutions, the wLS provides rapid control over individual excitation LED wavebands (Ultraviolet, Blue and Green/Yellow/Red). This enables the use of multiband pass filters instead of individual filters, followed by slow mechanical filter changes during multi-label imaging.

 

LED excitation provides many advantages over traditional fluorescence light sources, most notably eliminating one source of toxic Mercury from the lab. It also lowers operating cost with its 25,000 hour LED lifetime, which consumes 80% less energy.

A control handset is included which provides instant on/off and intensity control in increments of 1% to 100%, over each individual Ultraviolet, Blue, and Green/Yellow/Red (GYR) excitation waveband. When used with a QImaging camera, the on/off control is easily accomplished with the cameras expose out signal and the wLS TTL input. The wLS further extends control to popular microscopy automation and analysis packages with its USB interface.

Upgrading an existing microscope is easy. The wLS supports a comprehensive range of microscope adapters that fit to current and older microscope systems. A 3mm liquid light guide option is available for hard to adapt or non-microscope systems.
