Compensation of short- or far-sightedness. This can be done for each eye
individually by means of the two eye-pieces (range: +5 to -5 diopters).
Distance front lens to object level (= 300 mm).
Specifies the colour impression of a light source. Using colour temperature,
one can set the colour of a light source in relation ('hot' or 'cold' light) with
the colour of natural light (sunlight). The unit of measurement for colour
temperature is Kelvin (K).
The size of the field, which is illuminated at a distance of 300 mm.
The visible area of an object that can be seen through the colposcope. The
greater the magnification level, the smaller the field of view and vice versa.
A colour filter that darkens red and blue light and brightens green light.
Thus, the contrast of the image is increased, blood vessels are shown more
clearly.
Specifies the luminous flux from a light source onto a certain area. The unit
of measurement for illumination intensity is lux (Abbrev.: lx).
Light Emitting Diode. Electronic semiconductor device that emits light when
an electrical current passes through.
The optical portion facing towards the eyes, with which the enlarged image
produced by the colposcope can be viewed.
The two light beams for the eyes run together in a point that lies at a distance of
300 mm in front of the front lens. This distance is in accordance with the
working distance. This way, the eye does not has to focus on this point on its
own, as it is the case with a parallel beam path.
White balance is used to calibrate the camera to the colour temperature of the
light at the location.
(Digital single-lens reflex camera) with a digital imaging sensor.
(Charge-coupled device) a camera with a technology to store electro charge
and move this charge out of photo sensor in organized way.
(Complementary Metal Oxide Semiconductor) cameras in which image sensors
are silicon chips that capture and read light.
(Double beam splitter) Splits each light beam into two directions (eye and to
side port) for simultaneous user view & photography, videography or co-
observations.
Ratio of light distribution is 70% for eyes & 30% to side ports for photography,
videography or co-observations, installed between observation head and main
microscope.
