The SP-45001M-CXP4 provides the same 44.7-megapixel monochrome resolution as the SP-45000M-CXP4 but uses a reduced-speed version of the OnSemi XGS 45000 CMOS imager. This results in a list price that is more than 20 percent lower for customers not needing the ultra high performance of the full speed models. It offers the same high image quality and special functions of the higher-speed models, making it well suited to a wide range of high resolution applications.
