Single Negative (concave) Cylindrical lens – SNC
Example of a designation: SNC – M – DY – RZ
where:
M – material
Y – lens diameter (or width) in micron
Z – radius of curvature in mm
(ARZ - aspherical radius of curvature)
Applied materials are coded as follow:
Q – fused silica
GB – glass BK7
GT – glass S-TiH53 or S-TiH10
G – glass other type
P – plastic
P(G) – polymer lens on glass substrate
*The exact type of optical materials is underlined in the drawing.
*The exact type of aspherical coefficients is underlined in the drawing.

[aµs] manufactures the arrays with any pitch within a 10 µm – 4000 µm range and with any correlatable radius of curvature.
Arrays can be available as monolithic 2-side units with thickness from 2 mm to 10 mm.
Alignment preciseness of the lenslet optical axis on both sides is not worse than ±2 µm
Alignment preciseness of the lenslet optical axis on both sides is not worse than ±2 µm
