Sensor Head parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Silicon Photodiode 1× Blue-enhanced silicon photodiode whose photocurrent is linear with illuminance across more than seven decades.
2 Lumisphere 1× White translucent hemisphere over the diode that integrates light from the whole hemisphere with the cosine-weighted response a three-dimensional subject sees.
3 Lumisphere Slide Ring 1× Twist ring that retracts the sphere flush for measuring illuminance contrast or flat copy work.
4 Flat Diffuser Disc 1× Alternative flat receptor used when the lumisphere is retracted, reading light arriving on a single plane.
5 Spectral Correction Filter 1× Filter stack over the diode that reshapes silicon’s response toward the eye’s photopic curve so all light sources read consistently.
6 Head Swivel Mount 1× Detented rotating mount, about 270° of travel, that aims the receptor at the camera while the display faces the user.
