MONOCHROMATORS SPECTROGRAPHS

 The WM100 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. 

 The WM200 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 WM300 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 WM400 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 WM500 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.

 The WM600 monochromator-spectrograph is also available in a double-dispersive configuration, known as the Double WM300. In this setup, the output slit of the first WM300 serves as the input slit for the second WM300.

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