Frequently Asked Questions

Standard catalog items: no minimum order — even single pieces are available. Custom products: prototypes from 1 piece; typical production MOQ 5-10 pieces depending on specifications. Volume production: capable of 10,000+ pieces; pricing scales with quantity.

We accept bank wire transfer (T/T) as standard, plus PayPal and major credit cards for sample and small orders. Letter of credit (L/C) is available for large orders. Standard terms are 50% advance and 50% before shipment; for established customers, net-30 terms may be available after credit approval.

Yes, tiered pricing is available for volume orders. Typical discount tiers start at 10+ pieces, 50+ pieces, and 100+ pieces. Contact our sales team for a customized quote based on your volume requirements.

Standard catalog items: ships within 1 week after payment. Custom specifications: lead time subject to engineering evaluation — confirmed with quotation after review of your requirements. Complex custom optics: lead time determined during engineering review based on specifications, materials, coatings and quantity. All lead times are estimates, subject to final confirmation based on specifications and order quantity.

Yes, we ship worldwide via DHL, FedEx, and UPS. Shipping costs are calculated based on weight, destination, and service level selected. Import duties, taxes, and customs fees are the responsibility of the customer.

Absolutely! We specialize in custom precision optics including lenses, mirrors, windows, prisms, filters, and more. We can work from your drawings, specifications, or even reverse engineer existing parts. Contact our engineering team to discuss your custom requirements.

We work with BK7 optical glass, UV Fused Silica, Sapphire, CaF2, MgF2, Germanium, Silicon, ZnSe, and various optical crystals. Specialty materials can be sourced upon request.

We offer a full range of optical coatings: Anti-Reflection (AR) coatings for VIS, NIR, SWIR, MWIR, LWIR bands; High-Reflection (HR) coatings; Partial reflectors; Broadband coatings; Laser line coatings; and custom coatings for specific wavelength ranges.

Our standard precision includes: surface quality 40-20 scratch-dig, surface accuracy λ/4 @ 633nm, centration < 3 arc minutes. Precision options up to 10-5 scratch-dig, λ/20 surface accuracy, and < 30 arc second centration are available for critical applications.

Our quality management processes are aligned with ISO 9001:2015, covering incoming material inspection through final product testing and shipping verification.

Yes, we can provide inspection and test reports upon request including interferometer surface maps, spectrophotometer transmission/reflection curves, and dimensional inspection data. Certificates of Compliance (CoC) are provided with every shipment.

Our engineering team can provide technical support for material selection, coating recommendations, and manufacturability feedback. While we don't offer full optical system design services, we can recommend trusted design partners if needed.

We can provide sample components for qualification testing, typically at standard pricing with credit applied toward future volume orders. Contact sales to discuss sample requirements for your project.

All our optical components come with a 12-month warranty against defects in materials and workmanship. Products must be stored and handled according to recommended guidelines. If you receive products that do not meet specifications, contact us within 30 days for resolution.

Standard catalog items may be returned within 30 days in original, unopened packaging for a refund (less shipping costs), subject to a 15% restocking fee. Custom manufactured products are non-returnable unless they fail to meet agreed specifications.
