Perkins Precision Developments

Perkins Precision Developments (PPD) manufactures custom IBS coatings, including anti-reflection coatings. PPD utilizes Ion Beam Sputtering coating technology because it is ideal for complex spectral designs, high power Nd:YAG and fiber lasers and applications where it is critical to minimize losses from absorption and/or scatter. IBS thin films have densely packed micro-structures resulting in stable, easy to clean optics that are insensitive to environmental changes such as heat, humidity and pressure. Our AR coatings exceed damage thresholds of 25 J/cm² or sometimes even >60 J/cm² at 1064 nm.

Perkins Precision Developments (PPD) manufactures polarizing and non-polarizing beam splitters, beam splitter cubes, dichroic laser mirrors, prism polarizers, partial reflectors and output couplers for both R & D and OEM applications. Because we utilize Ion Beam Sputtering (IBS) coating technology, our beam splitters and beam splitter assemblies are environmentally stable, thus there is no spectral shift caused by either time, moisture or temperature.

As with all of our precision laser optics and optical assemblies, PPD's laser-line and broadband beam splitters and output couplers exhibit both low absorption and high damage thresholds (>20 J/cm²!), making them ideal for use with high energy Nd:YAG and fibers lasers as well as other high-power pulsed and CW laser systems.
