特征

Excellent Photodiode Linearity

全不銹鋼結(jié)構(gòu)

 

These photodiodes show excellent linearity over a large dynamic range. This is ideal for use in applications that require high accuracy measurements down to the pW level, especially when combined with a high sensitivity power meter that can accommodate the large dynamic range of the optical signal.

 

Responsivity Variation over Temperature

全不銹鋼結(jié)構(gòu)

 

A natural characteristic of a photodiode is for the its optical response to change as the temperature changes near the bandgap of semiconductor materials. Newport’s 918D series sensors feature a thermocouple near the photodiode, which allows certain Newport meters to read the temperature and automatically adjust the responsivity, ensuring the most accurate measurements.

 

Factors that Affect Maximum Measurable Power

 

The maximum measurable power of photodiode sensors is dependent on several factors such as the wavelength of incoming light, photodiode current output saturation, temperature, use of an attenuator and a power meter's maximum current input value. Newport provides maximum power specifications based on the power meter models, with and without an attenuator, and wavelength-dependent maximum power level. With these factors affecting measurable power in mind, choosing the proper detector for your application is critical.

 

增強(qiáng)功能

918D 系列光電二極管探頭通過*功能提升性能,旨在使其優(yōu)于 Newport 經(jīng)過業(yè)內(nèi)驗(yàn)證的 818 系列校準(zhǔn)光電二極管探頭。它們具有集成的校準(zhǔn)數(shù)據(jù)存儲器、內(nèi)置 OD1、OD2 或 OD3 衰減片(帶有電子衰減片開/關(guān)傳感器)以及用于溫度漂移補(bǔ)償?shù)膫鞲须娮悠骷墒固綔y器在溫度變化時(shí)測量更為準(zhǔn)確)。

寬動態(tài)范圍(具有內(nèi)置衰減器)

有的 OD3 衰減技術(shù)將我們探測器的校準(zhǔn)光學(xué)動態(tài)范圍擴(kuò)展了三個數(shù)量級。我們的衰減器設(shè)計(jì)提供高損傷閾值和光譜平坦度。通過與 Newport 正在使用的光電二極管相關(guān)聯(lián)的低 NEP,實(shí)現(xiàn)了更寬的動態(tài)范圍。對于小于 1 mW 的輸入功率,我們建議將衰減器置于 OFF 位置(對于 918D-UV-OD3R 在 200 - 400 nm 之間則為 0.1 mW),使信噪比達(dá)到大。該衰減器的通光孔徑為 10.3mm。

嚴(yán)格的校準(zhǔn)不確定性

918D 系列包括一個采用 NIST 可追溯標(biāo)準(zhǔn),利用 Newport 光學(xué)探頭校準(zhǔn)設(shè)施維護(hù)的高精度設(shè)備完成的全光譜響應(yīng)校準(zhǔn)。嚴(yán)格的校準(zhǔn)設(shè)備和過程控制可實(shí)現(xiàn)業(yè)內(nèi)嚴(yán)格的校準(zhǔn)不確定性。每個探頭都附有校準(zhǔn)數(shù)據(jù),這些數(shù)據(jù)以電子形式存儲在探測器的 EEPROM 中。每個探頭都附有校準(zhǔn)證書以及衰減器模式和無衰減器模式下的實(shí)際校準(zhǔn)曲線和數(shù)據(jù)。為了保持精度、保證性能,Newport 建議每年對光電二極管探頭進(jìn)行校準(zhǔn)。

Internal Temperature Sensor

 

The internal temperature sensor on the detector head is used to compensate the responsivity drift caused by the temperature change in the photodiode. The responsivity change is most sensitive around the bandgap, or towards the longer wavelength limit. The power meter calculates the temperature and automatically updates the responsivity value so that the measurements remain accurate. This feature is enabled with the power meter models 1936-R, 2936-R, 1919-R, and 841-PE-USB.

 

Photodiode Sensor Physics

全不銹鋼結(jié)構(gòu)

 

A photodiode consists of a semiconductor p-n junction similar to a laser diode and LED However, the fundamental radiation process involved is absorption. Light falling on the junction causes the formation of electron-hole pairs. In photovoltaic mode, the electron-hole pairs migrate to opposite sides of the junction, thus producing a voltage. One critical difference between a semiconductor photon source and a photon detector is that the former requires the use of a direct-gap semiconductor while the latter can utilize an indirectgap semiconductor. While the simultaneous requirement for energy and momentum conservation makes photon emission much less likely in indirect-gap semiconductors, this is not the case for absorption. A readily-achievable two-step process occurs where an electron is excited to a high level in the conduction band followed by a relaxation process where its momentum is transferred to phonons. Since this process can be sequential, it is much more likely than an emission process where the two steps must occur simultaneously. Please see our Photodiode Sensor Physics technical note for additional information.

 

Adapters for Fiber-Optic Applications

 

These photodiode sensors can be converted to measure optical power from connectorized or bare optical fibers. Newport offers a comprehensive set of screw-in fiber-optic adapters to match a variety of connector types. Our bare fiber holder and adapter mount are designed together to hold 250-µm bare fibers without damaging the fiber.
