Solid state lasers for high-performance laser excitation
With the increasing use of highly-complex cell-based 2D and 3D assays in biologic research, there is a pressing demand for improvements to the capabilities of automated high-content imaging. The ImageXpress® Confocal HT.ai High-Content Imaging System is a high-throughput solution that utilizes an 8-channel high-intensity laser light source to penetrate into deep tissue while reducing exposure times and increasing focus.
The illumination power of the laser light source significantly increases image intensity and assay sensitivity, which is especially important for dim samples. Imaging systems with lasers substantially decrease exposure times, which result in increased imaging speed and assay throughput. 3D imaging especially benefit from the laser light source with higher image intensities and improve image quality, which result in increased assay sensitivity and imaging speed.
AgileOptix technolgy with powerful, solid state light engine
AgileOptix technology makes it possible for the system to deliver the sensitivity and throughput needed for demanding applications by combining an advanced solid-state light engine with seven laser lines and eight filter combinations, proprietary spinning disk technology, state-of-the-art optics, and a scientific CMOS sensor.
Molecular Devices can successfully tailor the ImageXpress Confocal system to include customized software and hardware including the features described herein, as well as integration of other lab components such as incubators, liquid handlers, and robotics for a fully automated work cell.

Laser and LED light source specifications
The new modification of the ImageXpress Confocal HT.ai system equipped with multiline laser light source with matched filters spanning 405 nm to 730 nm excitation wavelength provides drastically increased illumination power to the sample. Laser light source results in brighter images, increased sensitivity, and increased speed and throughput speed of assays. The impact is especially important for the assays where sensitivity and timing are limiting factors.
Decreased exposure times with laser illumination
Confocal imaging and 3D image analysis are especially useful for capturing the complexity of 3D biological assays like organoids and spheroids. Here, we compared a standard imaging system with LED excitation to one with laser excitation.
