Narrow aspherical glass lens has chucking area

January 26, 2017 // By Julien Happich
Alps Electric has developed the “FLGPJ Series” Narrow Aspherical Glass Lens for compact, high-density optical transceivers.

The square aspherical FLGPJ Series has a narrow width of 0.6mm across and a chucking area at the top improves ease of handling during end product assembly, contributing to higher-density assemblies.

Despite its compact dimensions (0.6x0.8x1.5mm), the lens achieves an effective numerical aperture (NA) of 0.5. It employs lead-free glass compliant with both RoHS 6 and REACH regulations. Transmittance is 98% at 1310nm and 1550nm, focal length is 0.45mm at 1310nm.
