Product features:
1. Wide spectral range, wide application area Wide spectral range can be applied to a variety of different samples, such as responding to the deep ultraviolet detector in the solar blind zone; Solar cells that respond in visible light; Fiber optic sensors that respond in the near infrared; The spectral responsivity can be measured on this system for any photoelectric sensor that responds in the middle and far infrared
2. Monitor the light path to facilitate sample positioning
3. Using the monitoring light path, the use of high-precision microscope and CCD camera to achieve visual control of tiny devices, can clearly observe the position relationship between the test light spot and the effective area of the sample in the dark room, and with the precision displacement table to achieve accurate sample positioning
4.TurnKey "concept," OneKey "application, high system integration. Adhering to the "TurnKey" concept of "delivery is used", we will design the system
Highly integrated structure. On the premise of retaining the high compatibility of the modular system and large upgrade space, the integration of many adjustment links can be used without additional adjustment. In order to avoid the tedious operation of calibration, the system adopts alternative method for testing. As a general testing method for national metrology departments, the alternative method is more accurate and convenient than the traditional method, which avoids the tedious calibration of each related component in the system and the introduction of multiple errors
5. According to the structural characteristics of different devices, different test modes are configured to cooperate with two different optical path forms
5.1. Samples with small effective area need to be tested for responsiveness by illuminance method. Integrating sphere uniform optical path design, high optical uniformity In a wide spectral range of optical design, using integrating sphere to achieve uniform light output is a common means. A reasonable baffle set in the integrating sphere can effectively prevent the direct emission of the incident light and ensure the uniformity of the output light
5.2. For samples with large effective area, the flux method can be used to test the responsiveness. The full reflection imaging optical path can improve the light utilization rate and increase the signal-to-noise ratio. In the optical design of wide spectral range, the reflective optical path has higher image quality than the transmitted optical path. Chromatic aberration is an important factor affecting imaging in transmission-type optical systems, which comes from the different refractive indices of radiation of different wavelengths in optical materials, and the wider the wavelength range, the more obvious the chromatic aberration. In reflective optical systems, there is no chromatic aberration because there is no refraction involved. Therefore, the imaging quality is better than that of the transmitted optical path when the reflective optical path is used
