Array Negative (concave) Cylindrical – ANC
Example of a designation: ANC – a –
Py – Rz
a – material
Py – pitch in micron
Rz – 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
GL – glass S-LaH60
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
Pitch is the shortest distance between optical axis of two neighbouring lenses.
