Laserline Filters
Lightwaves2020 supplies industrial leading laser line filters for various applications. Lightwaves2020's coating, highly energetic process in conjunction with precise layer thickness control to atomic level, produces high performance and high quality optical thin film laser line filters with superior environmental stability.
 Features
- High transmission: > 90%
- Steep slope (roll-off to 5 OD): < 1% of laser wavelength
- Wide blocking range (customer application specific)
- Negligible temperature dependence of laser wavelength (can be as small as 0.7pm/oC)
- Hard dielectric coating with superior environmental reliability and durability (for telecom application, meeting Telecordia standards)
