Single Negative (concave) Lens – SNL
Example of a designation: SNL – M – DY – Rz
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
where:
M – material
DY – lens diameter in micron
Rz – radius of curvature in mm
(ARz - aspherical radius of curvature)
*The exact type of optical materials is underlined in the drawing.
*The exact type of aspherical coefficients 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
