20d lens:
this lens provides ultra resolution retinal image with the binocular indirect ophthalmoscope during clinical practice or in the operating room
20d diagnosticlaser lens is perfectly corrected for field curvature, astigmatic aberrations and coma – delivering the best retinal image.
It is designed further maintains linear image magnification and perfect image clarity across the entire field of view for unsurpassed fundus examinations.
Specifications
field of view : 46° 60°
image mag. : 3.13x
laser spot mag. : .32x
working distance : 50 mm
78d lens
this slit lamp lens offers an ideal combination of field and magnification. This lens provides an extended working distance from cornea.
The 78d aspheric lens is an excellent general diagnostic and laser treatment lens offering an ideal .93x image magnification and wide 97 dynamic field of view. It is optimally designed for use within the range of motion of all slit lamps.
Specifications
field of view : 81° 97°
image mag. : .93x
laser spot mag. : 1.08x
working distance: 8mm
primary application
general diagnosis and treatment.
90d lens
this slit lamp lens is the most popular power for non-contact fundus examination. It offers a wide-field fundus imaging out to and beyond the equator. A high magnification provides an increased illuminated field area which makes it ideal for posterior pole scanning.
