Abstract: An actuating and sensing module is disclosed and includes a bottom plate, a gas pressure sensor, a thin gas transportation device and a cover plate. The bottom plate includes a pressure relief orifice, a discharging orifice and a communication orifice. The gas pressure sensor is disposed on the bottom plate and seals the communication orifice. The thin gas transportation device is disposed on the bottom plate and seals the pressure relief orifice and the discharging orifice. The cover plate is disposed on the bottom plate and covers the gas pressure sensor and the thin gas-transportation device. The cover plate includes an intake orifice. The thin gas transportation device is driven to inhale gas through the intake orifice, the gas is then discharged through the discharging orifice by the thin gas transportation device, and a pressure change of the gas is sensed by the gas pressure sensor.

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.
