Our Capabilities
  •  knife edge lenses and hemispherical dome lensesPPO has 9 fully trained opticians, 1machinist and 1 optical inspector/assembler totaling over 200+ years of optical manufacturing experience.
  • PPO is ITAR registered
  • Complete gage calibration by an independent ISO/ANSI certified calibration lab
  • 60 conventional polishing spindles plus 9 single spindle polishing/grinding spindles
  • 2 curve generators,  1 plano grinding machine, 1 rounding machine
  • 1 SATISLOH C50 centering machine with freeform edging program
  • NEW - 1 SATISLOH SPM-55 CNC Curve Generator
  • NEW – 1 SATISLOH SPS-55 CNC Polisher
  • 1 Optotech assembly station
  • 1 - 4” Zygo Mark Series interferometer with Metro Pro and Windows 2007 fitted with a 1.5 meter laser Zygo Interferometric radius rail. 
  • 2 - 4” Zygo GPI interferometer with Metro Pro and Windows 2007 fitted with a 1.5 meter laser Zygo Interferometric radius rail. 
  • 4” transmission spheres f/0.65, f/0.75, f/1.5, f/3.3, f/7.2 plus 2 plano transmission flats
  • PPO manufactures spherical lenses ranging in sizes from 1mm to 100mm diameter.  Optical centering is fully supported to 60mm diameter with our Satisloh C50 centering machine. 
  • PPO has proven processes to routinely manufacture knife edge lenses and hemispherical dome lenses ranging in sizes from 3mm to 60mm diameter.
  • PPO works with all types of glass, Fused Silica and Calcium Fluoride.  PPO successfully produces CaF2 with surface irregularity tolerances < 1/10 wave and surface quality to < 20/10 scratch/dig requirements.
  • Typical tolerances with glass are +/-0.02mm CT, +/-2 fringes radius and < 1/8 wave surface irregularity.  We routinely polish to < 1/10 wave and often to <1/20 wave.
  • Proven polishing processes done with pitch result in low surface irregularity (1/20 wave) and low surface roughness (< 6 angstrom)
  • CNC processing for high quantity production, rapid lead times and competitive pricing
  • PPO has a complete machine shop on site allowing us to make all tooling and testplates in house
  • All work is done on work orders with a recorded manufacturing process and includes record of loss tracking for process improvement and lot traceability
  • Documentation routinely includes serialized inspection data for radius, irregularity, CT and SAGs.  Centering documentation includes all relevant centering data.  Surface interferograms can be provided upon request and will include radius and irregularity data.
