Long Edge Ultra-Steep

Steeper edges means better performance for your Spectroscopy instruments. High blocking edge filters eliminate the need for multiple filters for spectral noise reduction. All filters use hard dielectric coatings and do not require cover glass for durability. This greatly improves the transmission levels in all our filters compared to traditional filters.
