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.
Manufactured by HORIBA Scientific
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.
