9030DA单色仪

名称: 9030DA单色仪

型号: 9030DA

品牌: Sciencetech

  • 详细信息

9030DA双单色仪由两个串联的9030单色仪组成。在双重单色仪中,杂散光被大大减少,而在9030DA中,通过使用凹面全息光栅将杂散光进一步最小化。入射光被第一个光栅散射,然后又被第二个光栅散射。两个光栅同时沿相同方向旋转,并且在DA中耦合单色仪,以使色散是单个9030单色仪的两倍。对于相同的输出狭缝,带通是相应的9030单色仪的一半,使用100 μm狭缝的分辨率为0.4 nm。

9030DA - Double Additive Compact 100mm Monochromator

The 9030DA double additive monochromator consists of two 9030 monochromators placed in series. Stray light is drastically reduced in a double monochromator, and in the 9030DA it is further minimized by the use of concave holographic gratings. The inbound light is dispersed by the first grating and again by the second. Both gratings rotate simultaneously in the same direction, and in the DA the monochromators are coupled so that the dispersion is double that of a single 9030 monochromator. Bandpass is half of the corresponding 9030 monochromator for the same output slit, and resolution using a 100 μm slit is 0.4 nm.

This includes one set of standard slits, but the grating must be selected/specified separately.
