A large range of optional accessories are offered with the VSR instrument allowing you to get the right configuration for your demanding application 3 different telescope options are available wide field of view medium field of view and narrow field of view Additionally 2 different configurations of cold subtraction sources are offered to maximize the contrast A bore siding camera is available to help you point the instrument to remote targets 2 Packing and Visual Inspection 2 1 Front View of the VSR This is a view of the front side of the VSR instrument Connections are made on this side of the instrument The power supply block is removable and can be relocated from the instrument Figure 1 Front view of the VSR Description Cold subtraction source Optical module Contains the instrument modulator and detectors External heat sinks Help keep the instrument stable in temperature Power supply Provide power when not operating on airborne platforms Optical module access purge Electronic module Contains all the electronics of the instrument LR Tech Inc VSR Instrument User Manual 2 2 Rear View of the VSR This is a view of the rear of the VSR instrument facing the target it is currently observing Telescope and additional optics are installed on this side of the instrument Figure 2 Rear view of the VSR Description Electronic module Contains most electronics of the instrument Electr2. Hygroscopic Materials Notice If the beam splitter of your VSR is made from KBr material follow this section attentively This is a popular material used in IR spectroscopy because of its spectral coverage characteristics KBr is hygroscopic and must be manipulated and store with special care It withstands thermal and mechanical shock well but must not be cleaned with aqueous solvent glycerol the lower alcohols or stored in a high level of humidity environment Inside the sealed interferometer module with fresh desiccant the KBR is well protected Desiccant inside the cartridge must be replaced every year or if indicators 1 wire housekeeping humidity sensor or colored dots show internal humidity of 3096 or higher The Interferometer module Gold finish or stainless steel cylinder module most only be opened by authorized and trained personnel Mishandling of hygroscopic material may results in severe damage of the instrument Under the proper conditions KBR beam splitter will maintain its integrity for several year without any problems 5 Instrument Specifications The following specifications are for the standard version of the VSR If you have a custom modified version of the VSR please refer to the specific specifications provided to you 5 1 Instrument Weight Component Weight Kg VSR Instrument 21 Cold Source 1 Wide FOV Telescope 1 Medium FOV Telescope 3 2 Narrow FOV Telescope 7 Tripod With head
