1. Purpose and Features
1.1 Purpose
The surgical microscope OMS2360, OMS2365 (OMS2360, OMS2365) is applicable to the
microsurgery and fine examination of dental clinical subjects (except ophthalmology).
1.2 main structure composition
OMS2360, OMS2365 composed of the optical system, including the variable
magnification zoom lens, the binocular eyepiece, as well as the lighting system, stents,
electrical devices, can all be configured according to different application requirements
along with the corresponding accessories.
1.3 features
OMS2360, OMS2365 can enable teaching through built in photography and video capture
accessories.
OMS2360, OMS2365 use 190 °adjustable binoculars eyepieces that can be angled to match
the desired positioning for optimal operator viewing comfort.
A specially designed LED light source provides the maximum intensity of illumination needed
to work confidently.
OMS2360 for six times system, OMS2365 to five times.The eyepiece is wide Angle design, the
optical system image is clear, the field is big, the field is long.The built-in zoom lens provides a
larger range of work distance adjustment for doctors.
Built-in color filters with a yellow filter and green filter, Yellow for anti polymerization, green for
surgery.
Stepless brightness adjustment knobs conveniently located on the instrument allow for the
exact level of illumination required to be easily selected.
The cross arm is designed with a spring balance, so that the microscope stays at the right
operating height after positioning without moving up/down. While the microscope is in regular
use, the LED illumination will remain ON, and if the microscope is moved out of operating
range, the LED illumination will automatically turn off allowing for efficient storage when not in
use.
1.4 performance
After taking magnification into account, the viewing point of reference offset is not greater
than 10% of the diameter of the field.
The uniform illumination of the field of view has a color rendering index greater than 85%,
allowing for more accurate visualization of structures and media.
working noise of 65 dB (A) or less.
The large zoom objective lens working distance error is not more than 15%, for example the
shortest working distance is 200 +/- 30 mm, the longest working distance is 450 + / - 67.5 mm.
1.5 contraindications
No clear contraindications have been found.

are almost equivalent.
● When adding or removing accessories, readjustment of the balance of the second
arm is necessary.
4.3.2 Adjusting the microscope
● Carry out this adjustment in your normal working position, switch to 0.3 x magnification，
adjust the working distance and pupil distance of the microscope.
● Emmetropes/ operators who do not need corrective glasses：adjust the eyepiece to 0.
● Operators using his/her corrective glasses: adjust the eyepiece to 0.
● Ametropes/ operators who need corrective glasses who know their refractive powers
and perform surgery without wearing their glasses：adjust the eyepiece to his/her own
eyesight.
● Ametropes/ operators who need corrective glasses, who do not know their refractive
powers and perform surgery without wearing their glasses, use the following
procedure：Adjust both eyepieces to +5D，take the eyepiece and eyepiece tube from
the microscope, observe a distant object through the eyepiece, just like using a
telescope. Then rotate the diopter adjustment hoop until the image is clear. If
necessary, repeat this process for three times. Use the same method to adjust the
second eyepiece. Assemble the eyepiece and eyepiece tube back to microscope
body, tighten the fixation screw [10].
● Adjust the eye-cover until the whole visual field can be observed. Adjust the
magnification to 3x , when you feel the image is clear, return to the magnification you
want. The image is still clear when you change the magnification, but different in
depth of field for each magnification.
