Scientists can analyze variations in gene sequence and gene expression to identify the defective genes and polymorphisms that are associated with a specific disease. About half of such research is conducted in the field of cancer. These techniques provide initial insight into whether a potential drug merits further research and as such are immensely useful to drug discovery and development. The plurality of samples on a typical microarray is simply too demanding for most light sources. As a consequence scanners move chips or delivery optics to built up an image over time. Lumencor can eliminate that problem. By providing enough light to uniformly irradiate even the highest density chips, the noise and cost associated with moving parts and “scanning” are minimized and even eliminated. Lumencor light engines are being used today to obtain quiet, cost effective images based on single or multiple wavelengths.
