The CM-3700A allows you to select a target mask from three types: LAV (for ø25.4mm measurements),
MAV (for ø8mm measurements) and SAV (for 3×5mm measurements), according to the specimen and your
application. Select and attach a suitable target mask (illumination area) for each measurement area.
Target Mask
Each target mask is equipped with pins at the bottom of the target mask plate; the number and position of
these pins indicate to the Spectrophotometer which target mask is attached (and thus which illumination
area is being used). However, changing the target mask does not automatically change the measurement
area of the Spectrophotometer. Therefore, when changing the target mask, follow the direction of the color
conditioning software CM-S100w.
The target mask for SAV measurements is essentially the same as the one for MAV measurements, but
with a 0.3 mm-thick diffusion plate attached to increase the illumination area and reduce the edge-loss error
which occurs with semitransparent specimens.
The target mask surface which faces into the integrating sphere has a high-reflectance white coating. Since
the reflectance of this coating affects measurements, be careful to protect the white surface from scratches
and never touch the white surface.
Measurement Area
When the measurement area is switched from one to another, the condensing lens of the receiving optical
system is moved by the motor according to the commands from
the software running on a personal computer.
