Collimator Lens – High-Precision Laser Collimating Optics

⭐ Overview

Our collimator lenses are designed to convert divergent light from laser diodes or fiber sources into a parallel, stable beam. With high-precision optical materials, aspheric structures and advanced AR coatings, they provide excellent beam quality and long-distance stability.

Applicable wavelengths: 405 nm / 450 nm / 520 nm / 635 nm / 808 nm / 980 nm / 1064 nm / 1310 nm / 1550 nm.

⭐ Key Features

High Beam Parallelism – Stable and uniform collimated output
Aspheric Optical Design – Low divergence and high efficiency
Ultra-low Loss AR Coating – Ravg < 0.2% at custom wavelength
High Power Support – Optional fused silica for 10W–300W lasers
Precise Optical Tolerance – Ideal for industrial & scientific systems
OEM/ODM Customization – Coating, focal length, housing, size
