Blue laser lens from LightPath Technologies for commercial blue diodes

The 352673 molded glass aspheric lens is optimized to collimate Nichia’s 408 nm blue laser diode, and is designed for the specific beam divergences, peak wavelength, and window material of commercial blue diodes from 400 to 415 nm. It has a large clear aperture and compensates for variation in window thickness.

Blue Laser Collimating Lens

• Optimized for Nichia® blue laser
• Compatible with other blue diode lasers
• Aspheric molded glass lens
• Diffraction limited performance
• Compact, single lens design
• Short wavelength provides smallest spot

LightPath’s 352673 molded glass aspheric lens is optimized to collimate Nichia’s® blue laser diode, and is manufactured and designed to meet extremely stringent optical standards.

Achieving good beam quality is particularly difficult for shorter wavelength lasers. The 352673 molded glass aspheric lenses are designed for the specific beam divergences, peak wavelength and
window material of commercial blue diode lasers, enabling blue laser applications to achieve excellent beam quality and performance.

Working with lasers from 400 nm to 415 nm with a design centered at 408 nm per the laser manufacturers’ specification, this design was optimized with a very large and forgiving clear aperture and is also compensated for the laser manufacturers’ variation in window thickness.

The 352673 lens utilizes LightPath’s ECO-550 glass, a lead-free alternative to traditional moldable glasses. This glass is fully RoHS compliant, in accordance with the new European restrictions on
hazardous substances.
