Quality Thin Films (QTF) is now part
of the Edmund Optics^® Family!

Edmund Optics has acquired QTF, a leader in the industry offering a wide range of optical components with high laser damage threshold and laser crystal coatings from the UV to the far IR. This acquisition allows Edmund Optics to expand its laser optics manufacturing capabilities across crystal and glass fabrication, polishing, metrology, high laser damage threshold and diamond-like carbon coatings, inspection, and testing. QTF’s 14,000 square foot facility, located outside of Tampa, FL, is home to approximately 30 employees, many of whom are laser optics experts.

Capabilities

Depositing coatings with a high laser-induced damage threshold (LIDT) requires advanced process control and monitoring of manufacturing parameters, including cleanliness and coating repeatability. A continuous industry push towards higher-power lasers makes LIDT increasingly important for laser optics. QTF’s superior and proven high LIDT coating capabilities, combined with Edmund Optics’ in-house LIDT testing, ensure that the optics you receive can meet your application’s demanding LIDT requirements.

High LIDT coating options covering 248nm to 12µm
All common laser optics substrates including N-BK7 and Nd:YAG

Laser crystals function as gain media for solid-state laser sources. They are typically doped with rare earth or transition metal ions, which amplify the laser light through stimulated emission. Non-linear laser crystals are used for frequency conversion of laser sources. QTF has the capabilities to both polish and coat laser crystals in a wide variety of materials. Their precision polishing improves coating adhesion, which minimizes losses and increases LIDT.

Crystal materials including YAG, YALO, YLF, KTP, YVO4, PPLN, and PPSLT
Form factors including round, rectangular, and zigzag slabs
Crystal polishing and high LIDT coatings

LEARN MORE

Diamond-like carbon (DLC) coatings feature properties similar to natural diamonds like hardness and stress and corrosion resistance. They offer high transmission in the infrared (IR) and are ideal for harsh environment IR applications requiring anti-reflective coatings. They are often used in defense applications and applications that might expose the coatings to potential scratches, contamination, and stress.
