µPhase^® Lenses

µLens PLANO and SPHERO

The collimated test objectives μLens PLANO and the spherical objectives μLens SPHERO complement the μPhase^® interferometry systems and allow for increased flexibility and modularity of the complete system.

The μLens PLANO objectives allow for measurements of flat surfaces or optical systems in transmission from 2 mm - 150 mm. The spherical objectives μLens SPHERO enable to test spherical and aspherical surfaces with radii up to 225 mm (convex) and 98 mm diameter (convex), as well as optical systems in transmission.

Further Advantages:

• Existing μPhase^® systems can be expanded easily and at low cost thanks to the modularity and compatibility of the objective design.
• Testing of small samples with radii of curvature under 1mm is possible.
• High measuring accuracy through minimum wavefront aberration of μPhase^® and μLens SPHERO objectives.
• Field of view correction allows high measurement safety and interferometry with high fringe densities.
  

Select the Appropriate Objective from the Following Tables

Three Steps to Your Spherical Objective

1. Choose from "μLens SPHERO table" the spherical objectives which meets the requirement: CXmax > CS > CXmin or CCmax > CS> CCmin SPHERO"
   
   
2. Calculate the necessary f/# or max. diameter for the sample with
   
   
   
   and check if the objective is the right choice: check if the f/# of the choosen objective is smaller than the calculated value.
   
   
3. Choose from the table "μLens PLANO" the appropriate plano objective corresponding to the spherical objective
