LBTEK-High-power laser focusing lens

Product Description

Single-point low-reflection anti-reflective coating, R<0.25% at working wavelength
Air-gap quartz design, high damage threshold
Clear aperture: Ø18 mm
Outer diameter Ø30.5 mm, SM1 external thread on input end for easy installation

LBTEK laser focusing lenses are made of UV fused silica and feature an air-spaced design, enabling diffraction-limited focusing under high power while equipped with ultra-low reflectivity anti-reflection coatings (R < 0.25% @ operating wavelength). They are specifically designed and optimized for the three mainstream laser wavelengths: 355 nm, 532 nm, and 1064 nm, serving as cost-effective alternatives to high-power objective lenses. LBTEK offers high-power laser focusing lenses with operating wavelengths of 355 nm, 532 nm, and 1064 nm, covering focal lengths of 30 mm, 50 mm, 60 mm, 75 mm, 100 mm, 150 mm, and 200 mm. The mounting housing has a uniform diameter of Ø30.5 mm, with an SM1 external thread on the input end, and the surface is engraved with product model, focal length, and collimated light incidence side markings for convenient installation and use. Additionally, LBTEK provides flexible customization of dimensions and focal lengths. For details, please contact LBTEK technical support.

High-power laser focusing lens, 355 nm

Ultraviolet fused silica material, diffraction-limited design
Operating wavelength: 355 nm
Clear aperture: Ø18 mm

LBTEK laser focusing lens with an operating wavelength of 355 nm is made of UV fused silica, with a single-point low-reflection high-power anti-reflection coating at 355 nm, enabling diffraction-limited focusing under high-power lasers. The mounting housing diameter of the laser focusing lens is uniformly Ø30.5 mm, the incident end features an SM1 external thread, and the surface is engraved with markings such as product model, focal length, and arrow. The arrow points to the parallel light incident surface, facilitating customer installation and use.
