The optics wafer can include a blocking portion, which is substantially non-transparent for at least a specific wavelength range, and a transparent portion, which is substantially non-transparent for the specific wavelength range. The body includes a first surface adjacent the leading edge and at least partially oriented at a first angle relative to the mounting plane, a second surface adjacent the trailing edge and at least partially oriented at a second angle relative to the mounting plane, and an intermediate surface extending between the first and second surfaces. An energy change detector detects whether magnitude of energy supplied to the surgical instrument is changed or not. A seal material and a liquid crystal sealing port are provided on the first transparent substrate.
