裂隙灯使用要点(The slit lamp USES the key points)
This paper mainly introduces the function of slit lamp microscope, check, ad mainly judged by using the slit lamp microscope: the smooth surface of the lens and the integrity of the lens, so as to evaluate the process quality of the lens production; In the lens, there are all transparent impurities, spot adhesion and turbidity, etc., to infer the purity and mass of the lens materials. The surface of the old lens has no scratches, wear, and the type, color and form of the surface sediment of the lens.
2. Check the instrument before use
First, the focal rod is inserted into the corresponding socket of the instrument, and the lighting power (switch) is turned on.
According to the user's refractive error, rotate the adjusting ring of two eyescopes respectively:
Rotate the two eyepiece cones to align the center distance of the two mirrors with the eye contact.
Moving the microscope along the motion sliding table, the handle of one hand is coking in front and back, while the other hand grips the joystick before and after the handle, until the crack is as clear as it can be seen.
Observe the crack like brightness is sufficient and even. Generally not less than 20001x:
Open large fissures, turn the aperture disc, to see the shape of the aperture, whether the color filter is good and the rotation of the aperture is flexible. The fractur
