Ø7.4mm Collimator Lens
1. CAY046 is the most popular bi-aspheric plastic laser collimating lens which is nearly the diffraction limited.
2. CAY046 is specified for use as a collimator in combination with a diode laser.
3. CAY046 is designed for making a more fine dot at short distance. The focus is very close.
4. AR coating: 400~900nm.
