14. Dedicated digital microscope CCD/CMOS camera of resolution 5 Mpixels or better with USB
3.0 connectivity. Compatible C mount should be provided.
15. 3D Image analysis software capable of doing, measurements made by manually drawing on
selected image. Types include - Linear distance, Curved length, Area, Angle, Count, Grey
level. All measurements should be in real units. Width and colour of drawn lines may be
adjusted and labelled with measurements. Grouping so that objects that consist of multiple
fragments are measured as one. Results may apply to a single image or can be accumulated
over multiple images. Tracings may be stored and recalled for re-measurement by editing.
Advanced versatile features for producing excellent extended depth-of-focus images from
images acquired at different Z-positions. May create corresponding depth map and confidence
image. Automatic alignment of images obtained from non-telecentric optics.
16. Supplier should provide branded computer (HP/Dell) system with minimum specification of
Intel core i7 processor , 8GB RAM , 1 TB Hard disk, LED monitor of size 21 inch or more;
Minimum 1 KVA UPS with 30 minutes backup.
All the system like microscope, software and digital camera should be from the same
manufacturer for better comparability and future up gradation.
