Add CLUE to your SEM
Designed for your SEM and application
The CLUE family offers dedicated CL systems for imaging and
spectroscopic analysis suitable for most SEMs. In addition, when
combined with other techniques such as EBIC or EDS, CLUE adds
enhanced analytical capabilities to SEMs, by keeping the sample in
the same spot while performing these techniques.

The modular and flexible design of the CLUE systems provides
optimal CL performance for a wide range of applications, with
each component configured to satisfy most rigorous experimental
requirements. It also makes upgrading the system easy by adding
components to the existing CL-collecting interface.

Maintains
original SEM
functionality
In a CL experiment, the specimen is
excited by an energetic electron beam
from the SEM. The emitted light is
collected by a parabolic mirror installed
under the electron beam. The original
functionality of the SEM is maintained,
for the mirror is fully retractable.

High-efficiency CL
signal-collection
The customized CL-collecting system uses
a diamond-turned parabolic mirror designed
with optimal optical properties, e.g., wide
solid angle of collection for maximum
photon-capture and specific optical coatings
to enhance the efficiency at your working
wavelengths. The mechanical interface is
adapted for large-specimen chambers,
and is fully adjustable and retractable under
vacuum.
Please check with your local representative for
compatibility with your SEM.

Flexible spectral CL analysis
By separating the spectroscopic systems and CLcollector section, the CLUE series provides high
flexibility, ensuring compatibility with various types
of SEMs. In an environment of limited size, the
spectrometer is coupled to the collecting optics
via a fiber-optic cable. For extended capabilities,
a mirror-based coupling is available, perfect
for multi-spectrometer and/or multi-detector
systems, thereby optimizing the efficiency over
the various spectral regions of interest.
