Abstract: An apparatus for determining the effective case-hardening or nitriding depth of a steel component comprises a measuring head, including a laser source generating a variable frequency radiation for the scanning of pre-determined portions of the component to be measured; an infrared detector, configured so as to detect infrared radiation generated by the component to be measured; and computing means of spectra of the infrared radiation received; and an evolventimeter, connected to the measuring head and including first computing means suitable for computing a hardness profile of the component to be measured on the basis of a launch profile and spectra of the infrared radiation received and second computing means suitable for computing the effective case-hardening depth from the hardness profile computed.
