  • Page 227: Cleaning Procedures

    Cleaning Procedures The Cleaning Kit A full cleaning kit contains the following items: Isopropyl alcohol This is usually available from pharmaceutical suppliers or chemists. If possible, use alcohol supplied for medical purposes, rather than impure alcohol or alcohol with additives. Caution Do not use other solvents as some can damage plastic materials and claddings.
  • Page 228 Pipe-cleaner This is available from tobacco shops. Ensure that the bristles of the pipe-cleaner are soft, so that they do not scratch your device during cleaning. Caution Store your pipe-cleaners carefully and never reuse them as dust and dirt from the air or from previous cleaning can scratch and dirty your optical device.
  • Page 229 Do not use normal washing-up liquid, as it can leave behind an iridescent lm. These are available from HP. The part number is HP 92193N (80 Wipes per Premoistened box).
  • Page 230: Preserving Connectors

    Preserving Connectors Listed below are some hints on how to keep your connectors in the best possible condition. Making Before you make any connection you must ensure that all cables and connectors are clean. If they are dirty, use the appropriate cleaning procedure. Connections When inserting the ferrule of a patchcord into a connector or an adapter, make sure that the ber end does not touch the outside of the mating connector or...
  • Page 231 Dry means without index matching compound. If there is a need to use an index matching compound, use only HP index matching oil (part number 8500-4922). Clean the connectors, interfaces and bushings carefully each time after use.
  • Page 232 To assess the projection of the emitted light beam you can use an infrared sensor card. Hold the card approximately 5 cm from the output of the connector. The invisible emitted light is projected onto the card and becomes visible as a small circular spot. 1.
  • Page 233 Cleaning Connector Interfaces Caution Be careful when using pipe-cleaners, as the core and the bristles of the pipe-cleaner are hard and can damage the interface. Do not use pipe-cleaners on optical head adapters, as the hard core of normal pipe cleaners can damage the bottom of an adapter.
  • Page 234 Cleaning Bare Fiber Adapters Bare ber adapters are dicult to clean. Protect from dust unless they are in use. Caution Never use any kind of solvent when cleaning a bare ber adapter as Solvents can damage the foam inside some adapters. They can deposit dissolved dirt in the groove, which can then dirty the surface of an inserted ber.
  • Page 235: Cleaning Lenses

    Cleaning Lenses Some lenses have special coatings that are sensitive to solvents, grease, liquid and mechanical abrasion. Take extra care when cleaning lenses with these coatings. Lens assemblies consisting of several lenses are not normally sealed. Therefore, use as little alcohol as possible, as it can get between the lenses and in doing so can change the properties of projection.
  • Page 236 Cleaning Large Area Lenses and Mirrors Caution Some mirrors, such as those from a monochromator, are very soft and sensitive. Therefore, never touch them and do not use cleaning tools such as compressed air or polymer lm. Some lenses have special coatings that are sensitive to solvents, grease, liquid and mechanical abrasion.
  • Page 237 Cleaning Fixed Connector Interfaces A few instruments, such as the HP 8158B, have xed connector interfaces. Generally, avoid cleaning this kind of interface, because it is dicult to remove any used alcohol or lint from the input of the optical block. Keep the dust caps on the interfaces unless it is in use.
  • Page 238 4. Blow away any remaining lint with compressed air. Cleaning Fragile Optical Devices Some optical devices, such as the HP 81000BR Reference Re ector, which has a gold plated surface, are very sensitive to mechanical stress or pressure. Do not use cotton-swabs, soft-tissues or other mechanical cleaning tools, as these can scratch or destroy the surface.
  • Page 239 Cleaning Metal Filters or Attenuator Gratings This kind of device is extremely fragile. A misalignment of the grating leads to inaccurate measurements. Never touch the surface of the metal lter or attenuator grating. Be very careful when using or cleaning these devices. Do not use cotton-swabs or soft-tissues, as there is the danger that you cannot remove the lint and that the device will be destroyed by becoming mechanically distorted.
