Field Emission Scanning Electron Microscope (FESEM) with cathodoluminescence (CL)
Following minor changes and amendments have been made in the technical specifications for
better clarity.
S. No. Changes
1
Annexure 1 point 1(h) in place of
“The system should be capable of working as an environmental SEM with a variable
pressure mode for observation of biological/ non conducting specimens and the pressure
should be adjustable from 10 – 300 Pa.”
should be read as
“The system should be capable of working as an environmental SEM with a variable
pressure mode for observation of biological / non conducting specimens and the pressure
should be adjustable from 10 – 300 Pa. However, high vacuum systems having similar
overall performance will also be considered”

Annexure 1 point 5, the sentence
“The UPS should be able to support the ion pumps for at least 200 hours continuously when
there is a power failure.”
Should be read as
“The UPS should be able to support the ion pumps for at least 2:00 hours continuously
when there is a power failure.”
3
Annexure 1 Point 2, 3rd para
“Imaging with filter mode should be provided. The filter mode should allow pure secondary
electron (SE) signals, pure backscattered electron (BSE) signals and mixture of SE and BSE
signals to be detected by the in lens secondary electron detector.”
Should read as
Imaging with filter mode or equivalent should be provided. The filter mode should allow
pure secondary electron (SE) signals, pure backscattered electron (BSE) signals and mixture
of SE and BSE signals to be detected by the in lens secondary electron detector.

Annexure 1 Point 2, last para
At least more than two camera devices should be attached to the specimen chamber to
facilitate viewing inside the analysis chamber from top and side.
Should be read as
At least two camera devices should be attached to the specimen chamber to facilitate
viewing inside the analysis chamber from top and side.
