Tsubosaka SMD-100T2 Aperture light amount area meter

Light source: Halogen

Setting range: F-number selection – 12 types (F1.4–F32), AUTO; SENS switching – 4 systems (SENS1–SENS4)

Accuracy [%]: Measurement accuracy within ±3%

Collimator optical system: Parallel light lens diameter 100 mm

Subject to inspection:

・Aperture of a lens shutter camera

・Aperture of a focal plane shutter camera

・Lens aperture of an interchangeable lens (requires a jig)

・Aperture diameter when the sync contact of a lens shutter camera is in contact (or when the flash is fired)

・Aperture after the set time from the EXIT signal

Measurement items: Aperture error (dEV) relative to reference light intensity; Aperture error (△EV) ±2EV

Measurement range: -2.02 to +2.02 EV

Measurement method:

The amount of light passing through the aperture, after the object is irradiated with parallel light, is converted into an electric signal by a photoelectric element, and the ratio to the light amount of the amplified reference aperture is converted into an EV value.

Display / Operation:

・Main unit operation
