Overview

Gold coatings provide very high reflectivity across the infrared, from roughly 800nm through the far infrared, which is why gold mirrors are the standard metallic-mirror choice for thermal-imaging and IR-spectroscopy instrumentation. This is the same general coating category referenced on Dongqiao's IR Mirrors page — gold coating is one of the metallic options within that broader IR-mirror category, distinct from the dielectric coating used on wavelength-specific Laser Mirrors. Procurement review should center on using gold coating for infrared reflection while considering visible alignment and surface protection.

Key Selection Points

High reflectivity across the infrared, a standard choice for thermal-imaging and IR-spectroscopy mirrors
Chemically stable coating relative to some other metallic mirror coatings
Complements Dongqiao's existing IR Mirrors and thermal-imaging optics coverage

Applications

Gold mirrors are used in thermal-imaging systems, FTIR and IR spectroscopy instrumentation, and other applications requiring high reflectivity across the infrared spectral range.

Technical Reference

Spectral Performance

This module explains which spectral variables must be defined before measured performance can be reviewed. For Gold Mirrors, the module focuses on using gold coating for infrared reflection while considering visible alignment and surface protection.

Review measured performance against supplier or test-lab data tied to the exact configuration.
Record wavelength region, angle of incidence and polarization with the measurement context.
Confirm transmission, reflectance and blocking requirements against approved evidence for the selected configuration.
Product-specific review: connect infrared band with gold coating construction and document the trade-off against protected aluminum mirrors.

Frequently Asked Questions

Is this the same as your IR Mirrors page?

Gold coating is one of the metallic coating options within the broader IR mirror category — this page focuses specifically on gold-coated mirrors; see IR Mirrors for the general category overview.

Can I get a custom size or mount for Gold Mirrors?

Gold Mirrors requires this decision to be tied to infrared band and AOI and polarization. Share your drawing or exact dimensions through the RFQ form and we will confirm feasibility.

Which specification should be fixed first for Gold Mirrors?

Begin with infrared band. It determines how AOI and polarization and gold coating construction should be evaluated before the mechanical details are finalized.

When is Gold Mirrors a better fit than protected aluminum mirrors?

Choose between them by testing the requirement for using gold coating for infrared reflection while considering visible alignment and surface protection. If that requirement is absent, the comparison product may provide a simpler procurement path.

What should an RFQ for Gold Mirrors include?

State infrared band, AOI, whether visible alignment is needed and exposure conditions. Also include quantity, drawing revision and the required acceptance evidence. Final availability is confirmed during quotation.
