Optomechanical Medical Devices (Instruments) use lightwaves (UV, Visible, IR) for one or more of the following functions; to observe, to measure, to record, to test (align) and or to cut/repair.
The evolution of Optomechanical Medical Devices probably started when the first torch or candle or petrochemical lamp used a polished reflector (possibly with a concave configuration) to examine a part of a patient's body (possibly a wound).Once the glass lens was invented, light sources of any type could be forcussed to increase illuminating power on a selected area. Medical Devices have come a great distance since these early items. Skipping across time to three rather significant inventions and advancements, we are well into the era of Laser and Fiber Optics and Advanced Photodetectors, all being integrated into Medical Devices. The most notable fields have been Ophthalmology, Dermatology, and Surgery. All three fields have been able to incorporate both the use of the Laser and the use of Fiber Optics (and at times the use of Photodetectors), into a single device (instrument).
Historical: Philipp Bozzini (a Doctor, maybe) in the early 1800's used a hollow tube (tube material not identified) to project the light of a candle through the tube to view a patient's 'what ever'. Only Philipp, the patient and G-d knows what was being viewed. This ws the first recorded information on what could be considered the very first 'Endoscope examination'
The reward for doing a survey of commercially available optomechanical laboratory hardware is a stack of glossy covered thick
catalogs over a foot tall. On top of that you will have an additional foot of smaller catalogs and booklets. With a number of
selected articles written over the last few years you will have an excellent coverage of the field. Over the last thirty five years
(my coverage in the field) the amount and range of hardware has grown tremendously. As a first step, this paper presents an
organization of the field in nine main topics. The second level down (only partially covered to conserve space) gives a
number of sub topics which would appear in each of the main topic levels.
The reams of index pages in every catalog were surveyed in order to produce this two level organization. As a natural follow
on to the organization charts are the terminologies. It was felt that in a paper of this nature (again particularly to conserve
space) that "one-lines" would be in order. In an earlier paper (Fine adjustment for optical alignment) a number of little
controversies were stirred and it is assumed that will occur again. The words listed are defmed because of their frequent use in
this field. There are many times that definitions in the world of engineering are slightly "bent" to fit a particular field.
Therefore, "one-liners" are only a quick reference with further investigation and clarification obtained in a number of available
dicüonaries. Now that things have been organized and defmed, a section has been provided for comments "of special interest".
This will consist of industrial experiences, particular hardware worth mentioning and technical coverage, all related to the field
of optomechanical laboratory hardware.
