The two collimating lenses are then bonded to the bench.
The lens system includes collimating lenses L1, L3 and focussing lenses L2, L4.
The collimating lens group (312) has an optical axis (328) that is de-centered with respect to the axis (322) of the imaging beam (320).
The de-centered collimating lens group (312) enables the use of more conventional projection optics, without the unacceptable displacement of the projected image.
Further, the optical axis (328) of the collimating lens group (312) forms a non-zero angle with the axis (322) of the imaging beam (320).
A collimating assembly includes a plurality of generally parallel collimating vanes formed of a photon attenuating material.
An elliptical field of view light source that utilizes an array of collimator lenses is also described.
The light source, the at least one collimating lens, and the condensing lens are aligned in a straight line along the optical axis ensuring minimising space and cost, and maximising efficiency of light transfer.
