MONOCHRIMATORS / SPECTROGRAPHS

The M522 is a long-focal, automated universal monochromator-spectrograph known for its high spectral line quality and minimal stray light.

It supports up to two input and two output ports. The input port can be equipped with either a standard input slit or an optional crossed input slot. All spectral slits are automated, with software-controlled adjustable widths. Additionally, the slits feature a micro-screw for manual fine-tuning. Depending on the configuration, the M522 can be equipped with either a four-position diffraction grating turret or a single grating holder.

 The M266 monochromator is a versatile, high-aperture instrument offering excellent line quality and low stray light, with a 284 mm focal length and a 30×10 mm flat field. 

 The M266 monochromator-spectrograph is also available in a double-dispersive configuration, known as the Double M266. In this setup, the output slit of the first M266 serves as the input slit for the second M266.

This modification offers improved spectral resolution—twice the performance—along with reduced stray light, thanks to the larger focal length and added dispersion.

 The M150 is a versatile, compact monochromator-spectrograph. This low-cost, short-focus instrument offers flexibility and multifunctionality, combining impressive performance specifications with essential features typically found in larger spectrographs. 

 The MSA-130 is a compact double monochromator offering enhanced functionality and low stray light. Its standout feature is the ability to operate in both additive and subtractive dispersion modes, providing versatile performance for various applications. 

 The ML44 is a compact, high-aperture, short-focus monochromator that operates across the spectral range of 190-1200nm. When paired with a light source, the ML44 serves as an effective monochromatic illuminator for fluorescence excitation.
