MF-34

Overview

The new OEM compact monochromator MF34 has been designed around an aberration–corrected, type IV concave holographic grating. The diffraction grating plays a triple role:

  • Collimator 
  • Dispersing
  • Focusing

Features

  • Resolution: <1 nm FWHM (with 100 µm*4 mm slits) 
  • Wavelength accuracy: ± 1.5 nm with a fitting
  • More sophisticated motors can yield better wavelength

  • accuracy and reproducibility.

  • Step repeatability: ± 0.2 nm (with 1200 g/mm)

More sophisticated motors can yield better wavelength accuracy and reproducibility.

Specifications

With a 100 mm focal length and a F/2.6 aperture, the new MF34 is equipped with a rapid scanning direct drive system; the wavelength drive is directly coupled to a stepper motor

  • Concave grating.

  • Focal length : 100 mm.

  • Deviation : 34.7°.

  • Aperture : F/#:2.6.

  • Dispersion : 7 nm/mm (with 1200 g/mm).

Different models of slits are proposed depending on the resolution requested by the customer. The basic model is supplied with a pair of slits of 0.5 or 1 mm width.

Different models of stepper motors are proposed depending on the resolution requested by the customer.

In the basic model, the MF61 is equipped with a phases stepper motor with 12000 step/360°. The spectral range can be scanned in less than 1 sec.

The MF34 is made specifically for volume orders. We can offer custom modifications to volume customers.
