Compensation of short- or far-sightedness. This can be done for each eye
using the two individual eyepieces (range: +5 to -5 diopters).
Distance from the common main objective (CMO) to the object or area of
interest.
Refers to the color characteristic of a light source. Using color
temperature, one can set the color of a light source to 'warm' or 'cold'
light relative to the color of natural light. The unit of measure for color
temperature is Kelvin (K).
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 color filter that darkens red and blue light and brightens green light. This
improves the contrast of an image with red tones, improving the visibility
of blood vessels.
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 tubes through 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 from the common main objective (CMO). This distance is
equal to the working distance.
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.
(Charge-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 image
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, or co-observation.
The rotoplate reduces neck craning, making it comfortable to view hard-to-
see regions of the mouth from the 9 and 3 o'clock seated positions.
The double Iris diaphragm kit allows greater depth of field, which is
particularly valuable for photography.
