There are three basic parameters to consider when choosing a grating for your standard series monochromator

 

 A) Required Wavelength Range

 

The wavelength range available to you is determined by the grating groove density chosen and the angular mechanical limitation of the monochromator.

 

 B) Grating Efficiency

 

Ruled gratings may be blazed to increase their efficiency over a specific wavelength band.  Holographic gratings can be modulated such that they are more efficient at some wavelengths then at others.  Grating efficiency curves are the best tool for determining the most efficient grating available for your application.  It is important to note that grating efficiency curves do not represent the exact efficiency that should be expected when the grating is used in a monochromator as grating efficiency curves are taken at Littrow angle. 

 

 C)    Required Resolution and Bandwidth

 

Resolution is a measure of an instrument’s ability to separate adjacent spectral lines.  Resolution is generally given in nm.  The bandwidth (or bandpass) is the wavelength range that falls on the output port at any one time and is also given in nm.  This is an important parameter when integrating a camera such as a linear array or CCD on the output port of the monochromator.

Standard Czerney-Turner type monochromators suffer from astigmatism in the output beam due to the use of off-axis spherical mirrors.  Often the astigmatism is not an issue.  For imaging applications a torroidal mirror is used to compensate for the inherent astigmatism in the optical system produce a direct image of the input slit at the output port.  This is an important option for studying phenomena such as fast kinetics.

    9057F - Computer controlled 1/2m Monochromator, Fast Version

    The Sciencetech 9057F is a fast half meter motorized Czerny-Turner monochromator (and spectrograph) with an f/5.9 aperture. This is a "faster" model with larger optics for higher light throughput compared to the standard 9057 with f/8 aperture. Both models utilize a computer controlled motorized turret for automatic grating and wavelength selection. The regular 9057 model supports up to three 50 x 50mm gratings whereas the larger optics 9057F model supports up to two 64 x 64mm (clear aperture) gratings.

  2. 9057

    9057 - Half meter f/8 Monochromator

    The 9057 is a half meter monochromator and spectrograph with an f/8 aperture. This system is a Czerny-Turner design optimized to reduce aberrations.
    This monochromator supports up to three 50x50mm gratings on a computer controlled turret. It includes a single input slit by default; please select appropriate output mounting (slit, detector or CCD mounting, etc...) when ordering.
    A fast version of the 9057, the 9057F, operates with 64x64mm gratings and offers better throughput with the same optical pathlength. Please discuss with your Sciencetech technical sales staff member to find if the 9057F is a better choice for your particular application. Learn More

  3. 9055 250mm Monochromator

    9055F - Computer Controlled 1/4m f/2.5 Monochromator and Spectrograph

    The Sciencetech 9055F is a 250 mm focal length modified Czerny-Turner monochromator, with a flat field output for spectrograph use. This is designed as a faster version of the 9055 with larger optics for higher light throughput and f/2.5 aperture. All 9055Fs have a computer controlled, motorized turret for automatic grating and wavelength selection. Both input and output ports are situated on the front faceplate of the monochromator/spectrograph, and the system includes one adjustable SS80 slit at the input port. The 9055F supports up to two 64 x 64 mm (clear aperture) gratings.

  4. 9055DX

    9055DX-i Double Additive / Subtractive 1/4m Imaging Monochromator

    9055-DX is a motorized 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 .09nm with a 1200 l/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 tuneable bandpass or notch filter.
    This system includes two manual slits (one input and one intermediate). Motorized 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. Please speak with your Sciencetech technical sales member to ensure proper grating selection.
    Please see the technical datasheet for additional information.

    The imaging option 9055DX-i uses toroidal optics to compensate for astigmatism inherent in Czerney-Turner type monochromators and spectrographs. Learn More
