Laser Diode Collimator Lens-Anteryon AC405,10PCS

• AC405 is the Hybrid Aspherical Polymer on Glass lens, which is diffraction limited and have low wave front aberration.
• Long focus length (23mm) can provide more stable optical system.
• AC405 is the ideal choice for collimating or focusing the light of a laser diode.
