Etalon,F-P Etalon,Solid Etalon,Air-Gap Etalon
Photonchina Co., Ltd. manufactures solid-state and air-gap Fabry-Perot etalons designed for precision optical filtering and wavelength control. Their solid etalons use H-K9L or BK7 optical glass and quartz substrates, with surface parallelism better than 1-5 arc-seconds to ensure low wavefront distortion. Air-gap variants feature dual mirror stacks with controlled cavity spacing, enabling free spectral range values between 12.5 GHz and 500 GHz. These devices are engineered for applications requiring narrowband transmission, such as laser mode selection and spectral line analysis in atomic physics.
The substrate material choice directly affects thermal stability: fused silica is used when minimal temperature drift is critical, while silicon substrates are selected when a high temperature coefficient is needed for active tuning. Typical transmission peak finesse ranges from 10 to 50, depending on coating reflectivity and surface quality. Standard coatings are dielectric multilayers with reflectivity above 99% at target wavelengths. Surface roughness is maintained below 5 angstroms RMS to reduce scattering losses. These specifications align with industry standards for high-resolution interferometric systems used in telecom and laser research.
End users include laser manufacturers, spectroscopy labs, and optical instrumentation firms requiring stable, narrowband filters. Buyers typically request custom FSR values, transmission bandwidths, and mounting configurations. Packaging is done in anti-static, humidity-controlled containers with protective caps. Lead times vary by complexity, and samples are available upon request. Incoterms are typically FOB Fuzhou, with payment via T/T. All units undergo interferometric testing before shipment.

Sourcing Etalon,F-P Etalon,Solid Etalon,Air-Gap Etalon from Photonchina Co., Ltd. - China Import Guide
Before ordering, confirm the exact FSR, transmission bandwidth, and substrate material with the supplier. Request the interferometric test report for your specific unit to verify finesse, peak alignment, and reflectivity. Ensure the coating is designed for your laser wavelength, and ask for a sample if the application demands high precision. Do not assume standard specs apply - each unit is custom-built to order.
Lead time for custom etalons is typically 4 to 8 weeks, depending on complexity. Standard FSR units may be available sooner. Incoterms are usually FOB Fuzhou, with payment via 30% deposit and 70% against shipping documents. Buyers should request packaging details to ensure the etalon is protected from humidity and vibration during transit. Air freight is recommended for urgent deliveries.
Quality checks should include verification of surface flatness using a Fizeau interferometer, transmission spectrum analysis, and inspection of coating uniformity. Request documentation of the polishing process and coating stack design. Ensure the supplier provides a certificate of compliance with the specified FSR and finesse values. Inspect for scratches or contamination under magnification before acceptance.
