Doric Gradient-Index Lenses

These 0.5 NA cylindrical microlenses are obtained by drawing the fiber-optic preform with radial refractive-index distribution and specific Luneburg type profile into smaller diameter rods. Their main application is for fast axis collimation (FAC) of laser diodes.

The feasibility of the selected configuration is to be confirmed by the Sales department.

ORDERING CODE: DGI_D_h₁_h₂_L_S(λ₁-λ₂)

D - Rod diameter (mm)
h₁ - Rod height above optical axis (0.4 x D < h₁ <= 0.5 x D) in mm
h₂ - Rod height below optical axis (0.4 x D < h₂ <= 0.5 x D) in mm
L - Rod length (mm)
S(λ₁-λ₂) - Coating code

S is reserved for the lens coating specification code. The most common examples are provided in Preferred Coating Table. AR means Anti-reflective coating. Unless otherwise specified, R<0.5% across usable numerical aperture of the lens and within appropriate spectral range.

EFL = 0.685 x D

WD = 0.185 x D
