Hard Coated Laser Clean-Up Filters

Our TECHSPEC® Hard Coated Laser Clean-Up Filters feature high transmission, deep blocking, and are perfectly tuned for today’s high performance laser systems. Fabricated utilizing our state-of-the-art Advanced Plasma Reactive Sputtering coating platform; the filters feature hard, durable coatings on a single substrate, ensuring reliable performance and extended lifetimes.

Narrow bandwidths of 3 – 5nm are ideal for eliminating noisy spontaneous emission from laser sources. Broad bandwidths for diode wavelengths are ideal for eliminating background noise when detecting the laser source, improving the system’s signal-to-noise ratio. The filters feature maximum blocking within a few nanometers of the laser wavelength, making these filters ideal for the most demanding laser-based instrumentation and applications.
