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.

• 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 D-ZK3 Glass is used for all Laser Tool Lenses.

Aspheric lenses provide a single lens solution to laser projection. These aspheric lenses provide a cost savings over spherical doublets and triplets without sacrificing performance. Time consuming and expensive mounting and alignment of doublets and triplets can be replaced with a simple single lens mount.

Aspheric lenses also have higher transmission than multi-lens systems due to less optical material and allow more compact packaging to be produced.

• Single lens provides same performance as doublets and triplets

• Reduces system cost through simple, compact design

• Molded lenses for greater performance repeatability

• Designed for high volume production

Contact LightPath to take advantage of the power of Aspheric Optics for a simpler optical system.

In today’s manufacturing environment, laser tools are a common method for generating guidelines and measuring distances or surface profiles. These tools include laser levels, laser pointers, line projectors, laser scanners, and laser trackers. LightPath’s aspheric lenses are designed for use in today’s high performance laser tools and measurement systems.
