Glossary: Active diameter – Wavelength peak
14 Glossary
A
Active diameter
area of the effective optical cross-section of the
LED light beam at the optical guide tip
F
Ferrule
metal ring placed on the end of the optical guide.
Makes it easier to insert the optical guide into the
handpiece nosepiece and prevents the optical
guide from rotating.
Flexible protection shield
available in 5.5mm-diameter and 7.5mm-
diameter sizes. In contact with the patient, it must
be sterilised after each use. Suitable for
autoclaving. Previously called the cup
I
Irradiance
term used in radiometry to quantify the power of
an electromagnetic radiation per unit area. It is
expressed in watts per square metre. Often
confused with the power of a light source
L
LED
electroluminescent diode, more commonly
known as Led (light-emitting diode). Designates
an optoelectronic component that allows the
emission of monochromatic light
O
Optical guide
light conductor fitted to the handpiece nosepiece
and transmitting light to the cure site. Can be
cleaned and is suitable for autoclaving
P
Protection plug
two plastic plugs used to protect the handpiece
connectors and electronics during cleaning. One
fits to the nosepiece and the other fits to the
handpiece's electrical connectors
R
Rigid protection shield
removable oval shield forming an integral part of
the handpiece once in place. Cleaned with
wipes.Not suitable for autoclaving
W
Wavelength peak
maximum amplitude of a wavelength spectrum
