High-Precision Optics with Tight Tolerances - Custom & Stock for Your Projects
Dear Sir or Madam,
I’m Ella from Olis Optoelectronic Components Co., Ltd., a specialized manufacturer of optical components with over a decade of experience serving the laser, medical, semiconductor, and defense industries. I’m reaching out because I believe our capabilities could be a great match for your precision needs.
Here is a quick glance at what we can supply, with key specs highlighted in bold for your convenience:
· Spherical Lenses: Plano-convex, bi-convex, meniscus. Materials: N-BK7, UV Fused Silica, CaF2, ZnSe. Diameter: 3 mm – 300 mm. Surface quality: 40-20 S/D, centration: <3 arcmin. Coatings: AR@400-700 nm (R<0.5%), 532 nm & 1064 nm V-coat.
· Aspheres & Achromats: Precision-molded aspheres, achromatic doublets. RMS transmitted wavefront error: <λ/20. Coating: broadband AR 400-1000 nm.
· Mirrors: Protected aluminum, enhanced silver, dielectric HR. Flatness: λ/10 @ 633 nm, surface quality: 10-5 S/D. Reflectivity: >99.8% @ 1064 nm on Borofloat or Zerodur.
· Prisms: Right-angle, Penta, Dove, corner cube retroreflectors. Angular tolerance: ±5 arcsec, surface quality: 20-10 S/D, clear aperture: >90%.
· Windows & Optical Flats: UV to IR windows. Parallelism: <5 arcsec, thickness: 0.1 mm – 20 mm, transmitted wavefront: λ/10. Coatings: AR, BBAR, DLC.
· Filters & Dichroics: Bandpass (e.g., 532 nm ±2 nm), long-pass, short-pass, notch. Blocking: OD6, transmission: >90%, durable hard coatings.
· Polarizers & Waveplates: Glan-Laser, polarizing cubes, zero-order & achromatic waveplates. Extinction ratio: >10,000:1, retardation accuracy: λ/300.
· Germanium (Ge) Optics: Single-crystal Ge windows, lenses, and prisms for IR. Transmission range: 2–14 µm. Diameter: 2–200 mm, up to 300 mm on request. Surface quality: 20/10 S/D high-precision grade. Flatness: λ/10 @ 10.6 µm. AR coatings: 8–12 µm BBAR (R<0.5%), DLC/AR for harsh environments. Absorption: <0.02 cm⁻¹ @ 10.6 µm.
· Fluorphlogopite Mica (Synthetic Mica): Ideal for zero-order & multi-order waveplates, vacuum-compatible windows, and laser cavity spacers. Transmission: 190 nm – 3500 nm. Retardation accuracy: <λ/300 (ultra-high precision). Thickness: 0.05 mm – 0.5 mm for waveplates, up to 2 mm for windows. Temperature range: –200°C to +800°C with no delamination. Surface quality: 10/5 S/D, laser damage threshold: >5 J/cm² @ 1064 nm, 10 ns.
We hold a large in-stock inventory and also excel at custom optical design and OEM. Send us a drawing, and you will receive a detailed quotation within 24 hours. All components are tested with Zygo interferometers and comply with ISO 10110 / MIL-PRF-13830 standards.
Would you like to receive our full optical catalog and pricing list? If you have a specific requirement, I’d be happy to schedule a brief call. We can also arrange a free sample evaluation on standard items so you can test the quality firsthand.
Looking forward to your reply.
Best regards,
Ella Wang
