Thorlabs C660TME-C Mounted Geltech Aspheric Lens

The Thorlabs C660TME-C is a mounted Geltech™ molded glass aspheric lens designed to provide high-performance focusing or collimation with minimized spherical aberration. Aspheric surfaces are optimized to deliver improved image quality or beam shaping compared to simple spherical lenses.

Key Optical Specifications:

• Effective Focal Length (EFL): approximately 2.97 mm

• Numerical Aperture (NA): 0.6

• AR Coating: Broadband anti-reflection coating for 1050 – 1620 nm wavelength range, suitable for near-IR applications (e.g., fiber lasers, telecommunications wavelengths).

• Lens Type: Geltech™ molded glass aspheric (mounted in a mechanical housing)

📌 Typical Applications

• Coupling light into optical fibers or photodetectors

• Collimating output from laser diodes or fiber sources

• Miniature laser scanning or sensing systems

• Optical test setups and prototyping
