This is HOT selling one with beautiful design .
Features :
*Wide measuring range:Measuring range of standard cylinder lens can
reach up to 6D with the revolution 0.*5D.In the range of *0
,accuracy will be lower than 0.5 ,using the rotary prism with
trimming gear.
*Synchronal cross cylinder:Rotating of the cross cylinder is
synchronal with the adjustment of the cylinder axis.If you change
the axis,the cross cylinder will adjust to the appropriate position
synchronously,it is highly-efficient.
*Convenient operation,clear scale:With the special design,you can
switch to the appropriate lens quickly.Because of oxidation
treatment,all the scale and symbols are persistently clear.
*Multifunctional adjustment:P.D. can be adjusted from *8mm to
*5mm,quick switch between near P.D. and far P.D.,between near
visial angle and far visual angle.You can ajust the binocular
horizon and the distance between the vertex of the cornea and the
instrument.
*Multifunctional auxiliary lens:The complete set of SIGM VT*1
multifunctional auxiliary lens includes the following:Red-Green
lens,polarizer,prism,stenopeic lens,etc.You can switch quickly
between anyone of them.
*Fast and accurate conclusion:There are two spherical lens
turntables with 0.*5D and 3D diopter steps.Measuring
range:**6.*5D~0~**9D.You can adjust it much more accurately if you
use the 0.*2 auxiliary lens.
