Abstract: One embodiment of the present invention is an ophthalmic wavefront sensor for use with an ophthalmic microscope to provide continuous measurements of the refractive state of an eye. The wavefront sensor operates in both parallel sampling and lock-in detection mode by synchronizing the pulsing of the light source with a multiple number of position sensing devices/detectors used for detecting the centroid position of the sampled sub-wavefronts. Other embodiments include a beam scanner to sample selected portions of the wavefront and a live image sensor and a tracking deflector.

Abstract: An optical emission spectroscopic (OES) instrument includes a spectrometer, a processor and an adjustable mask controlled by the processor. The adjustable mask defines a portion of an analytical gap imaged by the spectrometer. The instrument automatically adjusts the size and position of an opening in the mask, so the spectrometer images an optimal portion of plasma formed in the analytical gap, thereby improving signal and noise characteristics of the instrument, without requiring tedious and time-consuming manual adjustment of the mask during manufacture or use.

Abstract: An integrated proximity and ambient light sensor assembly includes an emitter of an IR proximity signal, and a detector configured to detect the IR proximity signal from the emitter when the apparatus is sensing proximity, and to detect ambient light when the apparatus is sensing ambient light. The assembly includes an IR cut filter that has a film disposed over the detector that rejects IR light but passes visible light to the detector, and an opening in the film centered over a midpoint of the detector that passes IR and visible light to the detector. The opening allows IR light to reach the detector from within a narrow angle, but absorbs undesirable emitted IR light that is reflected by oily build-up or “smudge” left on a cover of the device. The film allows visible light to pass for a wider angle to better determine average ambient light.
