F number meter– SMD-81T2

F number deviations (dEV) are measured against the reference aperture diameter of cameras or replacement lenses, etc
The quantity of a parallel light passing through an aperture is accurately measured
The quantity of light can be measured in vertical or horizontal position of the product
F-No. can be changed easily with the knob
The sensitivity can be adjusted from WIDE to long focal point with a convenient 4 level switch
Full remote control with USB or RS-232 communication control
The parallel light lens model 100mm in diameter(SMD-100T2)
LED light source model(SMD-100T2LE)
