IPL Filters & Light Guides

Optical filter and light guide components for IPL systems requiring wavelength control, thermal stability and precise surface quality.

Microwork supplies custom IPL filters and IPL light guides for intense pulsed light systems used in aesthetic, dermatology and related optical equipment.

IPL systems typically use broadband pulsed light, often within the 400–1200 nm range. Filters and light guides are used to control the transmitted wavelength band, reduce unwanted UV or short-wavelength energy, guide the optical output and help protect the treatment interface.

Available Cut-Off Wavelength Options

Typical IPL filter wavelength options include:

• 515–1200 nm
• 530–1200 nm
• 550–1200 nm
• 560–1200 nm
• 570–1200 nm
• 590–1200 nm
• 615–1200 nm
• 645–1200 nm
• 695–1200 nm
• 755–1200 nm
• 780–1200 nm

Custom wavelength requirements can be reviewed according to the lamp source, coating design and application target.

Engineering Considerations

When selecting an IPL filter or light guide, engineers should consider the target cut-off wavelength, lamp spectrum, optical power density, heat load, cooling method, coating durability, surface quality and dimensional fit inside the handpiece.

BK7 is commonly used for cost-sensitive optical components, while fused silica may be preferred for higher UV transmission and thermal stability. Sapphire can be considered when mechanical durability, scratch resistance, heat resistance or harsh operating conditions are important.

Coating design is critical for IPL components. The final optical performance depends not only on the base material, but also on the cut-off coating, anti-reflective coating, surface finish and operating temperature.
