The SS82-HR is a high resolution bilaterally adjustable slit designed specifically for Sciencetech's large monochromators (models 9040, 9490, and 9150) due to their high resolution tolerance requirements. The slit has a manual micrometer knob for fine slit width adjustment between 0mm~6mm. The slit height can also be adjusted between 0mm~40mm through a manual metal curtain slider. However, the maximum slit height is limited by the 38mm port diameter of Sciencetech's large monochromators. Most Sciencetech large monochromators such as the Model 9040 already includes one Model SS82-HR slit at the input port. Purchase an additional slit only if a single-channel or PMT detector is to be mated to the output port. 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.
Dual Input Port Option
If the monochromator or spectrograph has the dual input port option, an additional SS82 slit is likely required if the port is directly coupled to a light source. An additional SS82 slit is likely not required if the input port is mated to an incoming illumination fiber bundle. In consideration of the many input possibilities, please ask our Applications Specialists for details pertaining to your particular requirement.
Dual Output Port Option
If the monochromator has the dual output port option, an additional SS82 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 SS82 slit is also likely required at the output port if the monochromator is to be used as a tunable light source. An additional SS82 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 SS82 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.
Model SS80 Standard Resolution Slit
Please note that this high resolution slit is for Sciencetech's large monochromators and spectrographs with focal lengths greater than 500mm (half meter). For Sciencetech standard size and small size monochromators and spectrographs, please consider Sciencetech Model SS80 Standard resolution slit which has less precision, but is significantly cheaper.
