Infrared Optics Questions, Answered for Engineering Buyers

We are an optical component manufacturer focused on infrared optics, optical filters, optical crystals, and related precision optical parts. Our team supports both standard components and drawing-based custom optics for engineering and purchasing teams.

Common material paths include CVD ZnSe, Germanium, Silicon, ZnS, CaF2, and other optical materials depending on wavelength, environment, coating target, and mechanical requirements. If you are not sure which material fits your application, share the wavelength band and operating conditions for review.

Yes. We can review customer drawings for dimensions, tolerances, surface quality, coating requirements, quantity, and delivery schedule. For custom optics, the final feasibility, tolerance, coating stack, and lead time are confirmed during engineering review and quotation.

Useful inquiry details include material, wavelength band, dimensions, thickness, surface quality, flatness or radius, coating target, operating temperature, quantity, drawing file if available, and target delivery date. Clear specifications help reduce back-and-forth and improve quotation accuracy.

For available stock items, there is usually no strict minimum order quantity. For custom or out-of-stock parts, MOQ depends on material, geometry, coating, processing complexity, and setup requirements. Small-batch prototype orders can be reviewed case by case.

Yes. Sample availability depends on existing stock, material type, and requested specifications. You can send your requirement through the contact form, and we will confirm whether a stock sample or custom sample path is practical.

Lead time depends on stock status and manufacturing complexity:

• Available stock items: usually 1-3 business days after confirmation.
• Drawing-based custom optics: commonly 7-25 business days, depending on material, quantity, coating, and inspection requirements.

A confirmed delivery date is provided with the quotation or order confirmation.

Inspection can include dimensional checks, visual inspection, surface quality review, coating appearance, and packaging verification. Depending on the order requirements, we can provide inspection records, material-related documentation, or coating information for customer review.

Coating support depends on the material, wavelength band, angle of incidence, substrate geometry, and durability target. Please provide the transmission or reflection target, wavelength range, and operating environment so the coating requirement can be reviewed before quotation.

Optics are packed to reduce contact, abrasion, dust, and handling risk during transport. Packaging method depends on component size, coating sensitivity, order quantity, and shipping destination. Special packing requirements can be discussed before shipment.

Common payment methods include bank transfer (T/T) and PayPal. If your purchasing process requires a different method or documentation workflow, contact us before placing the order.

Production capacity depends on product type, material, tolerance level, coating, and inspection requirements. For planning purposes, please share the part type, drawing, annual or batch quantity, and delivery schedule so we can review a practical production path.
