As a new brand of FE-SEMs, the Regulus series lineup comprises four models: the Regulus8100, Regulus8220, Regulus8230, and Regulus8240, all of which extend the functions of the SU8200 series with the use of a common platform.

With optimized electron optical systems, the new Regulus series features resolutions down to 0.7 nm in the Regulus8220/8230/8240 models and 0.8 nm in the Regulus8100 model.​
