Masking off
areas of interest
The Reflex aperture allows areas outside you sampling area to be
masked off. The dual apertures prevent light from reaching the
medium surrounding your sample and minimize the effects of scatter
and diffusion, particularly as your sampling area approaches 50 µm.
Using the TruView feature, you can view the sample at all times,
including during data collection. In dual aperture mode, this allows
you to see the actual area that is exposed to the infrared beam. The
outlying areas that are masked by the Reflex aperture are not visible.
By positioning the aperture while viewing the sample, you ensure
that “what you see is what you get.”
Each time the microscope is powered on, the physical aperture
initializes. At the end of the initialization, the physical aperture is
synchronized with the virtual aperture that is tracked by software.
The Reflex aperture illumination control adjusts the illumination
intensity of the aperture image in either transmission mode or
reflection mode.
The selectable, adjustable, Reflex aperture lets you define the
infrared beam area, ensuring that the infrared energy strikes only the
area of interest and not the adjacent sample medium. It also ensures
that the small amount of diffracted radiation that passes around the
edges of the sample area of interest does not reach the detector.
