상품 상세설명




MS520 series 


Monochromator-spectrograph MS520 series have a unique combination of high-intensity, accuracy and spectral resolution. Large angle of rotation of the grating allows to use Echelle grating, providing extremely high spectral resolution (up to 0.002 nm), as well as extended operating wavelength range for the other gratings.

MS520 are completely automated spectral devices with focal length of 520 mm and F-number of 1/5.4.

High-quality optics and wide choice of diffraction gratings provide devices operation in a wide range from 185 nm up to 60 ?m (depending on the selected grating).

M520 Series monochromator-spectrographs are based on Cherny?Turner asymmetric scheme that allows to minimize of aberrations and exclude spectra re-entrance from diffraction gratings and mirrors.

Model MS5201i and model MS5204i have the astigmatism-corrected optics what makes these devices applicable in multi-channel spectroscopy.

Monochromators?spectrographs of MS520 series have one input port and two output ports. Selection of an output port is realized with an automated mirror. Either output spectral slits or multi-channel detectors can be installed on each of the output ports.

We offer monochromators?spectrographs of MS520 Series with two types of input and output spectral slits: manual, operated with a micrometer screw and automated (combined), when the slit width is operated automatically or manually (with micrometer).

A wide choice of changeable gratings gives the best combination of high energetic efficiency and maximal spectral resolution for different spectrum areas.

We also offer a wide range of additional accessories for Monochromators?spectrographs of MS350 series: Filter Wheel FWS-8A, -6A, Fast shutters, Fiber optics with adapters, input and output Condensres, Detectors and etc.

Extremely high spectral resolution ? 0,0020nm for Echelle grating 75 grooves/mm - in combination with small size and a variety of configurations and accessories make monochromators-spectrographs of MS520 series ideal devices for high resolution spectroscopy and Raman spectroscopy. High optical throughput makes it essential for luminescent investigations.

In the devices with the standard optics (model MS5201 and model MS5204) a flat entrance deflecting mirror is used, and in the astigmatism?compensated devices (model MS5201i and model MS5204i) a cylindrical mirror is used as an entrance deflecting.

As well as in all Czerny?Turner design spectral devices, in the MS520 series an axis of the diffraction gratings rotation goes through the center of grating operating surface and coincides with the direction of grooves. This fact provides the stability of the geometry of the beams for formation of a flat and fixed focal field. The image quality in the whole flat focal field is optimized due to the use of an asymmetric scheme and use of a focusing large-size mirror allows one to use the whole focal field width without vignetting. Besides, Cherny?Turner asymmetric scheme provides a low level stray light and light re-entrance from the optical elements and detectors can be avoided.

In MS5204 and MS5204i the gratings rotation axes are arranged perpendicular to the spectrum scanning axis, providing a high repeatability of wavelength setting at replacing of gratings.

Optical scheme is optimized for:

  • minimization of coma aberration over the whole operating spectral range
  • elimination of the light re-entrance from two basic mirrors
  • elimination of the light re-entrance between mirrors of the instrument and input windows of the detectors in the focal plane
  • a large plane focal field for the whole operating spectral range
  • astigmatism compensation for the whole operating spectral range by means of special correcting optics (for imaging modifications MS5204i and MS5201i)
