Visible-NIR Mirror
Chenyu Optics supplies custom Visible-NIR mirrors according to the required reflection band, average or minimum reflectivity, angle of incidence, S/P polarization condition, substrate, surface flatness, surface quality and coating durability. Final reflectivity is confirmed for the specified wavelength range and measurement conditions rather than treated as one universal value.
Visible-NIR Mirror Overview
Visible-NIR Mirrors use a coating designed for a stated visible-to-near-infrared reflection band. The usable band must be defined numerically in the quotation or drawing.
Reflectivity may be specified as an average value across the band or a minimum value at every required wavelength. Angle of incidence and S/P polarization affect the coating response, particularly at non-normal incidence, and must be stated with the reflectivity requirement.
Chenyu Optics supports drawing-based Visible-NIR mirror production with substrate, dimensions, surface flatness, surface quality, clear aperture and coating durability requirements reviewed for prototype and repeat production.

Visible-NIR Mirror Selection Comparison
| Selection Factor | Visible-NIR Mirror | Broadband Dielectric Mirror | Protected Aluminum Mirror | Laser Line Mirror |
|---|---|---|---|---|
| Spectral Design | Specified visible-to-NIR reflection band | Broad dielectric reflection range defined by coating design | Broad metallic reflection across UV/VIS/NIR regions, depending on design | Narrow wavelength or defined laser-line range |
| Reflectivity | Specified as average or minimum across the required VIS-NIR band | Confirmed for the designed broadband range | Lower than many dielectric designs but covers a wider spectral range | Optimized for the specified laser wavelength and AOI |
| AOI & Polarization | Must be specified for coating review | Must be specified, especially at non-normal incidence | Generally less spectrally selective, but AOI still affects system behavior | Critical to reflectivity and laser-line performance |
| Choose When | The system needs a defined visible-to-NIR band with controlled dielectric reflectivity | A wider dielectric reflection band is required | Broad spectral coverage and metallic-mirror behavior are more important than maximum dielectric reflectivity | The system operates at one laser line or a narrow laser wavelength range |

Visible-NIR Mirror FAQ
What wavelength range do Visible-NIR mirrors support?
Visible-NIR mirrors are designed for reflection applications covering visible and near-infrared wavelength regions.
What is the difference between a Visible-NIR mirror and a broadband mirror?
Visible-NIR mirrors are optimized specifically for visible and near-infrared reflection, while broadband mirrors may cover wider spectral ranges.
Can Visible-NIR mirrors be used in laser systems?
They can be reviewed for laser systems when wavelength, angle of incidence, polarization, beam conditions and coating requirements are specified. LIDT should only be stated when supported by applicable test data or an agreed verification method.
Can the mirror size and coating be customized?
Yes. Custom dimensions, substrates, coating ranges, and optical specifications are available.
What information should I provide for a quotation?
Please provide the reflection wavelength band, average or minimum reflectivity, angle of incidence, S/P polarization condition, substrate, dimensions, surface flatness, surface quality, coating durability requirement, quantity and drawing. Include an LIDT requirement only with defined laser and test conditions.
