Abstract:
A conventional capacitive accelerometer has a limitation in reducing a distance between a sensing electrode and a reference electrode, and requires a complex process and a separate method of correcting a clearance difference caused by a process error. However, the capacitive accelerometer of the present invention has high sensitivity, can be simply manufactured by maintaining a very narrow distance between a reference electrode and a sensing electrode, and can make it unnecessary to individually correct each manufactured accelerometer by removing or drastically reducing a functional difference due to a process error.

Abstract:
An apparatus for testing transmission of a lens includes a light source, a focusing device, an integrating sphere, a moveable carrier, a detector, and a processor. Light, in a specific wavelength range, is emitted from the light source. The focusing device is configured for collimating and focusing the light to transmit the light onto the lens being tested. The integrating sphere is configured for receiving light transmitted through the lens. The moveable carrier is configured for facilitating a relative movement between the lens and the integrating sphere. The detector includes a light sensor configured for detecting a light intensity received by the integrating sphere and transforming the light intensity into a comparing signal for comparison. The processor is configured for comparing a signal of the intensity of the light transmitted to the lens with the comparing signal to obtain a transmission efficiency/percentage of the lens.
