The standard filters for use with LDSS are listed in Table 3. Observers may supply their own filters. The specification is that the diameter must be 100mm (0.1mm) and the thickness less than 8mm. Filters should only be installed by qualified personnel. In the case of user-supplied filters, staff should be notified in advance to give time for any additional spacers to be manufactured.
