An optical lens set to form a lens comprising a first lens set element (30) including a lens (31) having a curved lens surface (32) having an entrance pupil with a first diameter (41), wherein the first lens set element if of a first width (39) taken along a direction perpendicular to the optical axis; and a second lens set element (40) including a lens (44) having a curved lens surface (46) having an entrance pupil with a different, second diameter (48) which is smaller than the first diameter. The second lens set element has an inner part (56) and an outer part (54; 154), the inner part including the second lens (44). The outer part (54) extends to a second width (52) which is greater than the width of the first lens set element, in order to improve handling and stress propagation characteristics for the smaller, second lens (44).
An optical lens set comprising:
An optical lens set according to any preceding claim, wherein said first width is the maximum width of said first lens set element perpendicular to said first optical axis and said second width is the maximum width of said second lens set element perpendicular to said second optical axis.
An optical lens set according to any preceding claim, wherein said first or second set element has a protrusion which is shaped to interfit with a surface of said second or first set element, respectively.
An optical lens set according to any preceding claim, wherein said outer part includes a removable part arranged to be removed during an assembly process.
An optical lens set according to any preceding claim, wherein said inner part is attachable to said first optical element to form a lens stack, and wherein the thickness of said outer part in a direction parallel to said second optical axis is greater than the maximum thickness of said lens stack when so formed.
An optical lens assembly comprising an optical lens set according to any preceding claim, wherein said first and second lens set elements are mutually attached.
A method of assembling an optical lens set comprising:
