FIRST IN PHOTONICS
The Sciencetech 9055 series are 250mm asymmetric focal length modified Czerny-Turner monochromators. They have a flat field output for use as a spectrograph. The 9055 model has an f/3.5 aperture, although a faster f/2.5 is available as a 9055F model. The 9055 series has a computer controlled turret for automatic grating and wavelength selection.
Both the input and output port are located on the front faceplate of the monochromator, and the system includes one SS80 slit at the input port.
This system does not include gratings, software, or a host computer. If you require any of these components, please contact us to discuss your options.
For applications requiring better signal to noise, reduced stray light and better resolution than the standard model, a double additive/subtractive model (9055DX) is available.
9055DX is a motorised double 1/4m monochromator that can be switched between additive and subtractive configurations. Double monochromators have the advantage of extremely low stray light levels by virtue of using two gratings. An intermediate slit between the two units, used to define the wavelengths that pass to the second unit, also masks off light scattered within the body of the first unit. In double additive operation the 9055DX effective focal length (1/2m), dispersion and resolution (1.7nm/mm and 0.09nm with a 1200l/mm grating) are doubled compared to a single unit, making this mode useful where high resolution is important. In double subtractive operation there is no dispersion in the output beam and only a single slit image appears at the output instead of a broad spread of spectral images. This allows the system to operate as a tunable bandpass or notch filter.
This system includes two manual slits (one input and one intermediate). Motorised upgrades and additional slits may be purchased separately. Gratings also need to be purchased separately, with a minimum of 2 gratings required for the system to operate.
We also also offer an imaging monochromator (9055DXi) which uses toroidal optics to compensate for astigmatism inherent in Czerney-Turner type monochromators and spectrographs.
The 9057 series of standard monochromators are also available.
