SFS Double-Convex Lens

Mastering the Spectrum: The Premier Choice for UV-NIR Focusing

The VenusLab SFS Series Double-Convex Lenses are versatile focusing elements engineered for high-precision optical systems. Fabricated from premium JGS1 UV Fused Silica, these lenses offer superior thermal stability and spectral transmission compared to standard BK7 glass, excelling in broadband applications ranging from Deep UV (185nm) to Near-Infrared (2000nm).

The symmetrical bi-convex design is optimized to minimize spherical aberration in 1:1 imaging (unit conjugate) scenarios. With a high-precision Surface Quality of 40-20, the SFS Series ensures minimal scattering loss and maintains excellent wavefront quality for demanding laser applications.

Key Applications

• UV Laser Systems:Ideal for 266nm, 355nm laser focusing and beam expansion due to JGS1's UV transparency.
• High-Power Laser Focusing:Quartz material withstands higher thermal loads than standard glass.
• Imaging Relay Systems:Perfect for 1:1 image transfer in optical trains.
• Biomedical & Fluorescence Instruments:Low autofluorescence material ensures accurate signal detection.
