Of course it does, that is what it is designed to do.

And what is a Light Meter designed to do?

A Light Meter is designed to determine a desired EXPOSURE - for the chosen photo-sensitive material. That photo-sensitive material could be a film emulsion or a complementary metal–oxide–semiconductor. The Light Meter doesn't care. The Light Meter produces suggested EXPOSURE settings that work across media, from different film emulsions to N-type metal-oxide-semiconductors, complementary metal–oxide–semiconductors or any Charged-Coupled Device that will take an optical image and convert it into an electric signal and then via software into a bitmapped image. And if you really want to understand CCD or CMOS "noise" do some research into real-time imaging software.

The bottom line is,

The Light Meter doesn't care. The Light Meter is doing what it is designed to do. It is a device that takes an optical image and converts that into an electric signal. It works with any film emulsion. Any CCD. Any CMOS. And at almost any ISO setting.

The Light Meter doesn't care how big the film is or how big the CCD or CMOS sensor is or what the focal length of the lens is or what the maximum aperture of a lens is or what the size of the Circle of Confusion is.

The Light Meter doesn't care. It produces EXPOSURE setting recommendations that work. It is not however, a Sonic Screwdriver that takes some thrown together techno-jargon and whip that into some Equivalentist Evangelical creed.
