Our Specialization

Notch Optics specializes in manufacturing a wide range of high-performance optical filters covering the spectrum from 240 nm to 2600 nm. These filters are crafted using advanced deposition methods such as Ion Beam Sputtering (IBS), Leybold APS, or Ion-Assisted E-beam (IAD) deposition systems. Each method is chosen to ensure that the coatings meet stringent requirements for optical performance, laser damage threshold, and environmental stability.

Key features of Notch Optics's optical filter manufacturing capabilities include:

Deposition Methods: Utilizing Ion Beam Sputtering (IBS), Leybold APS, or Ion-Assisted E-Beam (IAD) to deposit thin film designs that optimize performance across various applications.
Substrate Compatibility: Coatings are applied to wafers, custom optics, polymers, fibers, crystals, semiconductors, garnet, and glass substrates up to 200 mm in diameter.
Clean Room Facilities: Ensuring compliance with rigorous surface quality standards to meet demanding application needs.
Design Flexibility: Notch Optics's design team collaborates closely with customers to identify and create optimal filter designs tailored to specific requirements. Sample designs can illustrate theoretical coating performance under varying conditions, such as angle of incidence, substrate type, incident medium, and wavelength range.
