A machine for measuring the optical properties of a lens for a pair of eyeglasses includes a light emitting system for emitting a light beam; a receiver arranged for receiving the light beam; an alignment system configured to align the lens according to a predetermined measuring position; a gripping system configured to grip the eyeglasses; and a supporting system on which the eyeglasses or the single lens are positioned. The alignment system is arranged at a distance from the light emitting system so that at least a lower support element is not intercepted by the light beam. The gripping system is in a closed configuration after the alignment has been performed and then a subsequent shifting of the support structure is carried out to bring the lens under the light emitting system.

Methods for compensating measurements of devices under test (DUTs) captured through prescription lenses (and associated imaging systems, devices, and methods) are described herein. In one embodiment, a method for characterizing focus quality of a DUT through a prescription lens includes adjusting an optical power of a measurement device to compensate for optical power provided by the prescription lens. The method further comprises imaging, using the measurement device, a test pattern through the prescription lens, wherein the test pattern is displayed by the DUT; measuring contrast of an edge in the test pattern at a point of interest within the imaging of the test pattern; and determining focus quality of the DUT based at least in part on the contrast measurement.

An apparatus, system, and method for a see-through optical verification tester are described herein. In some aspects, a heating element such as a Peltier or Thermoelectric Cooler TEC may be used to control a temperature of an optical element. In examples, the see-through optical transmission tester includes a see-through void and may control temperature, humidity, and pressure of an environmental enclosure to facilitate optical see-through and reflective tests.

Examining a light optical element (LOE) may include placing a first slit optically between a projector configured to emit light and the LOE's first major surface and placing a second slit optically between the LOE's second major surface and a detector. Facet parallelism between two facets may be deduced based on a shift of the image reflected from the first facet to the second facet relative to light transmitted normal to the first and second major surfaces through a portion of the substrate not including a facet. Facet refractive index homogeneity or deviation may be deduced based on the light transmitted through the facet relative to light transmitted normal to the first and second major surfaces through a portion of the substrate not including a facet.
