9055DX单色仪

名称: 9055DX单色仪

型号: 9055DX

品牌: Sciencetech

  • 详细信息

9055-DX是电动双1 / 4m单色仪,可以在加法和减法配置之间切换。通过使用两个光栅,双单色器具有极低的杂散光水平的优势。两个单元之间的中间狭缝(用于定义传递到第二单元的波长)也掩盖了散射在第一单元主体内的光。在双重加法操作中,与单个单元相比,9055DX的有效焦距(1 / 2m),色散和分辨率(在1200 l / mm光栅下的色散和分辨率(1.7nm / mm和.09nm)增加了一倍,使该模式非常有用重要。在双减法运算中,输出光束中没有色散,并且在输出处仅出现一个狭缝图像,而不是光谱图像的广泛散布。

该系统包括两个手动狭缝(一个输入和一个中间)。电动升级和其他狭缝可单独购买。

光栅也需要单独购买,系统运行至少需要2个光栅。请与我们联系,以确保正确选择光栅。

9055DX - Double Additive/Subtractive 1/4m Monochromator

9055-DX is a motorized double 1/4m monochromator that can be switched between additive and subtractive configurations. Double monochromators have the advantage of extremely low stray light levels by virtue of using two gratings. An intermediate slit between the two units, used to define the wavelengths that pass to the second unit, also masks off light scattered within the body of the first unit. In double additive operation the 9055DX effective focal length (1/2m), dispersion and resolution (1.7nm/mm and .09nm with a 1200 l/mm grating) are doubled compared to a single unit, making this mode useful where high resolution is important. In double subtractive operation there is no dispersion in the output beam and only a single slit image appears at the output instead of a broad spread of spectral images. This allows the system to operate as a tuneable bandpass or notch filter.

This system includes two manual slits (one input and one intermediate). Motorized upgrades and additional slits may be purchased separately.

Gratings also need to be purchased separately, with a minimum of 2 gratings required for the system to operate.
