The Sciencetech 9010 is a 200 mm focal length, asymmetric Czerny-Turner scanning monochromator. The standard model has an f/3.5 aperture. The "faster" model 9010F has larger optics for higher light throughput and an f/2.6 aperture. Both models have a manual selector dial with readout for wavelength selection. Up to two gratings are supported on its sine drive rotating turret. A manual knob on top of the monochromator allows the user to select the active grating. Two bilaterally adjustable slits for its input and output ports, and two gratings are included.
The 9010 and 9010F scanning monochromators offer optimum resolution for all spectral ranges and low stray light levels. The optical layout has been optimized for minimum aberrations over the entire spectral range consistent with low stray light. The asymmetry of the layout is optimized for coma correction over a wide range of grating angles and line separations. This allows for good overall resolution and not just at the nominal wavelength. Please note that the 9010 and 9010F do not have a flat field output for spectrograph use, and therefore can only be used as scanning monochromators.
 
Port Locations
The input port can be optionally relocated onto the side panel with the use of an internal 45º mirror (9000-sideport-9010). The reason for this relocation is to allow sufficient space between the two ports for mating detectors, fibers or input light sources to them. If the two ports are located on the same front faceplate, their close proximity may not have enough room to mount such accessories.
 
Drive Mechanism
The 9010/9010F utilizes a manual sine drive mechanism to rotate its grating turret for wavelength selection. A manual control knob with readout on the side of the 9010/9010F allows the user to select the wavelength of the active grating. The gratings are mounted back to back on the rotating turret with the forward facing one being active. To switch between the two gratings, a separate manual knob at the top of the monochromator allows either of the two gratings to be forward facing, and thus making it active.
 
Bilaterally Adjustable Slits
The 9010/9010F monochromator includes two standard SS80 manual bilaterally adjustable slits pre-mounted at the input and output ports.
 
Available Detectors
Sciencetech has a wide selection of single channel and PMT detectors for use with the 9010/9010F monochromator. This includes a large collection of silicon, germanium, InGaAs, PbS, and other room temperature and cooled detectors. A range of PMT detectors are also available for low light applications. Please remember to purchase a corresponding detector mount with the detector. See Sciencetech's detector section for details. Since the 9010/9010F cannot be used as a spectrograph, linear array detectors such as CCDs and Photo-diode arrays cannot be used.
 
Similar Monochromator Models
The 9010 does not have a flat field output and therefore cannot be used as a spectrograph. Please consider the manual control 8010 spectrograph if the application demands a spectrograph configuration utilizing a linear array detector. For computer controlled motorized applications, please consider the 250mm Computer Controlled 9055 monochromator/spectrograph with a built-in motorized grating turret. A motorized version of the 9010/9010F with an external stepper motor is available upon special request, but not recommended due to the availability of the 9055.
