PEEK integrating sphere

PEEK integrating sphere

Core Features

  • Superior Diffuse Reflectance: When precision-machined from high-purity PEEK, the internal surface provides excellent lambertian reflectance, essential for uniform light distribution and measurement.
  • Extreme Thermal Stability: Maintains a perfect spherical geometry and dimensional accuracy in continuous operating temperatures up to 250°C (482°F).
  • High-Purity & Low Outgassing: Manufactured from 100% virgin PEEK, ensuring zero metallic ion contamination and minimal outgassing, which is critical for sensitive optical sensors in vacuum environments.
  • Absolute Chemical & UV Immunity: Completely resistant to aggressive cleaning solvents and organic acids, with high natural resistance to UV degradation that could yellow or degrade lower-grade plastics.
  • Precision CNC Port Machining: Engineered with sub-millimeter tolerances for detector ports, light entry points, and sample holders, ensuring seamless integration with fiber optics and sensors.

At Kriloha Ltd., we understand that in precision optics, even the slightest structural deformation can lead to significant measurement errors. Our PEEK Integrating Spheres are our engineered answer for “Uniform-Light-Precision” and “Total-Environmental-Isolation”. As a premier provider of customized PEEK solutions, Kriloha has developed a specialized manufacturing division that translates complex optical and mechanical requirements into high-performance protective realities.

The engineering of our spheres is founded on Structural-Rigidity and Surface-Integrity. By utilizing state-of-the-art 5-axis CNC machining, we eliminate the structural inconsistencies often found in standard plastic housings, ensuring perfectly aligned internal mounting points and robust wall thicknesses. At Kriloha, we verify the dimensional stability of every sphere under maximum thermal load, resulting in “Failure-Resistant” interfaces that protect your sensitive instrumentation in the most demanding environments.

Manufacturing these advanced optical components involves strict Dimensional, Thermal, and Purity Verification. We collaborate directly with your engineering teams to process bespoke configurations—including integrated wiring channels, proprietary mounting tabs, and non-standard port layouts—ensuring the sphere perfectly integrates with your hardware. By choosing Kriloha Ltd., you are investing in a “Future-Proof” manufacturing partnership that optimizes your system’s reliability through superior material performance.

Primary Use Cases

  • Optical Sensor Calibration: Providing a uniform light source for calibrating high-precision cameras and photodetectors in aerospace and laboratory settings.
  • Spectroscopy & Laser Analysis: Acting as a mixing chamber for measuring total luminous flux or spectral power distribution of lasers and LEDs.
  • Semiconductor Metrology: Specialized optical housings used in wafer-handling systems where metallic contamination and particulate generation are strictly prohibited.
  • Medical Diagnostic Instrumentation: Non-magnetic and radiolucent frameworks for MRI-compatible optical sensors and diagnostic imaging hardware.
  • Aerospace & Satellite Radiometry: Lightweight, high-strength protective spheres for avionic sensors that must survive extreme altitudes and high-vibration environments.

Frequently Asked Questions

  1. Why use PEEK for an integrating sphere instead of Aluminum?

Metal housings can interfere with electromagnetic signals, are prone to corrosion, and transfer heat rapidly to internal electronics. PEEK provides the structural strength of a metal while being non-magnetic, non-conductive, and thermally insulating.

  1. Can these spheres be used in Ultra-High Vacuum (UHV) environments?

Yes. PEEK has exceptionally low outgassing properties, making these spheres an industry standard for semiconductor vacuum chambers and aerospace instrumentation where maintaining vacuum integrity is mandatory.

  1. Is it possible to integrate metal inserts or mounting points?

Absolutely. We can manufacture custom PEEK spheres with over-molded or press-fitted stainless steel or titanium inserts to provide specific mechanical attachment points while maintaining total isolation.

  1. How does PEEK handle exposure to aggressive cleaning chemicals?

PEEK is chemically inert to almost all organic solvents, acids, and bases. The sphere will remain structurally sound and will not dissolve or swell when cleaned with industrial-grade reagents.

  1. Are custom layouts available for non-standard port sizes?

Yes. As a customization specialist, Kriloha can process proprietary geometries, custom-shaped internal compartments, and unique mounting interfaces based specifically on your CAD designs.
