	However, BL-04518MP125-IRCLD was not specifically designed for panoramic applications: while the resolution in the center is sufficient, the peripheral one is significantly lower. Panoramic applications are specific - ~~it requires~~ ''uniform resolution'' in every part of the image.

	While we are able to compensate for aberrations and vignetting to match the resolution of the current 5-megapixel sensors by elaborate post-processing, we would definitely benefit from the higher lens quality when upgrading the sensors in the future. Therefore we have specified the following requirements.
