Modulation contrast converts the difference in surface heights of a sample to brightness contrast for observation. This allows for samples to be viewed in 3D and thus this microscopy is suitable for observing sperm and egg cells.

Biopsy and ICSI 


Microscopes for an optimized IVF procedures flow

CooperSurgical offers ideal solutions to allow optimised ICSI and Biopsy work in the lab. 

Our workstations can be equipped with inverted microscopes with room for manipulation that offer high resolution and high contrast imaging.

Modulation / Relief Contrast for IVF Procedures​

Also called relief contrast microscopy,or Hoffman modulation contrast, this technique is used when observing colourless, transparent samples. ​
