The Model SS83 Motorized Bi-laterally adjustable slit is the motorized upgrade to any Model of Sciencetech's bilaterally adjustable slits. An electrical actuator replaces the manual micrometer thumbwheel for computer control. Most Sciencetech monochromators/spectrograph models already include one manual slit at the input port but an additional one at the output port is usually required if the monochromator is to be mated to a single channel detector, PMT detector, or used as a tunable wavelength light source. Hence if the customer purchases a Sciencetech monochromator and an additional slit, two Motorized Upgrades will be required. Each motorized slit requires a a USB port to control it. Sciencetech's motorized slits come with Windows Active-X Software. The slit width can be adjusted between 0~5.5mm, in 10µm increments. Sciencetech also offers a line of height adjustment options with manual control.

Where To Use A Slit
Most Sciencetech monochromators such as the Model 9055 already includes one manual Model SS80 slit at the input port. Only purchase an additional slit for the output port if a single-channel or PMT detector is to be mated to the output. Multi-channel linear array detectors such as CCDs and Photo-diode arrays do not require a slit at the output port. Additional slits may also be required if a dual input or output port is selected. Please contact a Sciencetech Applications Specialist at sales@sciencetech-inc.com if you are unsure whether an additional slit is required in your application. 

Motor Controller
Please note that a USB port is required to operate each motorized slit. 

Software Control
A free Active-X software comes with the Motorized slit to control its width. The controller also includes option for local control through an interface panel.

Standard vs High Resolution
The manual control Model SS80 slit is a standard resolution slits designed for Sciencetech's regular line of monochromators/spectrographs such as the Model 9010, 8010, 9055, 9035, and 9057. These monochromators and spectrographs have focal lengths between 200mm to 457mm. The manual control Model SS82-HR slit and computer control SS83-HR slit are both high resolution slits designed for Sciencetech's large line of monochromators/spectrographs such as the Model 9040, 9490 and 9150. These monochromators and spectrographs have focal lengths between 500mm ~1.5m. It is not recommended to cross use the slits between the different classes of monochromators. Using a standard resolution slit on a large size monochromator/spectrograph will degrade its optical resolution. Using a high resolution slit on regular size monochromator/spectrograph will not improve its optical resolution.

Model 9010 Monochromator
Please note the the Model 9010 Monochromator already includes two manual SS80 slits for both input and output ports. Therefore, upgrade prices are available for both ports.

Dual Output Port Option
If the monochromator has the dual output port option, an additional slit is likely required if the output port is to be mated to single channel or PMT detector. In addition to this slit, these detectors also require a specific detector mount. An additional SS80/SS83 slit is also likely required at the output port if the monochromator is to be used as a tunable light source. An additional SS80 manual or SS83 motorized slit is not required if the outport is mated to a multi-channel detector such as a CCD, photo-diode array or linear InGaAs detector and used as a spectrograph. For such detectors, please check our selection of multi-channel detector mounts which is required. An additional SS80 slit is also not required if an output fiber is attached to the output port. In consideration of the many possibilities, please ask our Applications Specialists for details pertaining to your particular requirement.
