The range is whatever energy range you have specified in the optical properties for your materials (see Section 5.2.5 of the Dev Guide) in your application. Geant4 doesn't provide predefined optical properties, so it's up to you.

You can define infrared optical photons all the way down to millikelvin temperatures, if you have the microwave-scale complex index of refraction; or up into X-rays, if you can specify the reflectivity for say an XMM-Newton mirror.
