Compensation of short-or-far-sightedness. This can be done for each
eye using the two individual eyepieces (range: +5 to -5 diopters).
Distance front lens to object level (250mm).
Refers to the colour characteristic of a light source. Using colour temperature,
one can set the colour of a light source to warm or cold light Relative to the
colour of natural light. The unit of measure for colour temperature is Kelvin (K).
The size of the field, which is illuminated at a distance of 250mm.
The visible area of an object that can be seen through the microscope. 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
measure for illumination intensity is Lux (Lx).
Light Emitting Diode. Electronic semiconductor device that emits light when an
electrical current passes through it.
The optical portion facing towards the eyes, with which the enlarged image
produced by the microscope can be viewed.
The two light beams for the right and left eye run together at a point that lies at
a distance of 250mm 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
in its own, as it is the case with a parallel beam path.
White balance is used to calibrate the camera to the color temperature of the
light at the location.
(Digital Single Lens Reflex) camera with a digital imaging sensor
(Charged Coupled Device) camera with a technology to store a charge and move
this charge out of the photo sensor in an organized way.
(Complementary Metal Oxide Semiconductor) camera in which images sensor
is a silicon chip that captures and reads light.
(Double Beam Splitter) splits light beam into two directions (one to eye and one
to side port) for simultaneous user viewing and photography, videography, or
co-observation. Ratio of light distribution is 70% for eyes and 30% to side ports
for photography, videography and co-observation.
