Edge optical filters
ECI designs edge filters for use in applications that require excellent durability and environmental stability.

• All-dielectric materials
• Steep transition
• High transmission with low pass band ripple
• Rejection levels typically better than < 0.1% (OD 3)
• UV, visible and NIR applications
• Substrates up to 175mm in diameter
• Filters meet environmental requirements of MIL-C-48497

• Typical Edge Pass filter designs:
