The Krug and Lau interference microscope (Fig. 4.26) is also 

 based on the same principle. The beams are spht on the 45°-slan- 

 ted semi-reflective face G, located in the prism Q. Rienitz also 

 achieved particular interference microscopes based on a similar 

 principle. 



Hilger and Watt, and C. Baker, have also designed two-wave 

 interference microscopes for investigating reflective objects. The Hilger
