名称: 9072DS单色仪www.2138.com

型号: 9072DS

品牌: Sciencetech

  • 详细信息

在9072DS中,第二个单色仪中的光栅布置得使第一个单色仪的光谱色散反转。这会在第二个单色仪的输出端口处产生光谱均一的光束,并大大减少了杂散光,非常适合太阳辐射的光谱辐射,拉曼或UV测量。

 

9072DS的排列使其可以用作可调带通滤波器或可调陷波滤波器。作为可调带通滤波器,设备的带通由中间缝隙的宽度决定。当布置为可调陷波滤波器时,该陷波的宽度由放置在中间狭缝位置的不透明陷波的物理宽度确定。

 

9072DS还可以用于通过使用自定义的中间多狭缝掩模而不是单个宽度的中间狭缝来通过或滤除几个选定的波长。

9072DS - Double Subtractive 1/8 m (125 mm) Computer Controlled 

Monochromator/Spectrograph with USB

In the 9072DS, the grating in the second monochromator is arranged such that it reverses the spectral dispersion of the first monochromator. This leads to a spectrally homogenized beam at the output port of the second monochromator and greatly reduced stray light, ideal for spectroradiometry, Raman or UV measurements of solar radiation. 

 

The arrangement of the 9072DS allows it to act either as a tunable bandpass filter or a tunable notch filter. Arranged as a tunable bandpass filter the bandpass of the device is determined by the width of an intermediate slit. When arranged as a tunable notch filter the width of the notch is determined by the physical width of an opaque notch placed at the intermediate slit position. 

 

The 9072DS can also be used to pass or filter out several selected wavelengths by using a custom intermediate multi-slit mask instead of a single width intermediate slit.
