Frequently Asked Questions

Q. I intend using a laser beam with a Reflecting Objective. What beam diameter should I use for best performance?

A. Ideally the beam should fill the secondary (small convex) mirror. Diameters are to be found in the Interface Drawings above.

Q. I intend using a laser beam with a Reflecting Objective. What focussed spot size will I get?

A. For a Gaussian beam filling the secondary (small convex) mirror the the 1/e2 spot diameter = 2λ/πNA.

Q. Does the central obscuration affect the spot size?

A. No, though there will be more energy in the outer diffracted zones. Please see our technical paper for furtther information.
