890–920nm High Reflectivity Mirror | R>99%, 45° AOI

890–920nm High Reflectivity Mirror | R>99%, 45° AOI

The OPTOStokes 890–920nm high reflectivity mirror is engineered for precision near-infrared beam control. Ion-assisted dielectric thin-film coating delivers reflectance greater than 99 percent across the full band at a 45-degree angle of incidence, ensuring low-loss beam folding and wavelength combining with minimal wavefront distortion for OEM laser systems and NIR optical assemblies.

Technical Specifications

Applications

This NIR mirror serves 45-degree beam steering and wavelength combining in laser systems, 3D scanning and LiDAR modules, NIR spectroscopy, laser rangefinders, and multi-channel detection setups. The 890–920nm range covers common 905nm and 915nm laser sources used in industrial sensing and measurement.

Customization & Service

OPTOStokes manufactures this mirror in round, square, and custom geometries with optional edge bevels and anodized aluminum mounting rings. Standard diameters are maintained in stock for fast shipment, while custom substrates, dimensions, and coating variants are supported through our in-house coating facility. Every optic undergoes spectral verification and surface inspection before dispatch. Understanding AOI effects on coating performance is critical — our engineering team can advise on angle-tolerant designs for non-standard configurations.

Procurement & Support

Long lead times and inconsistent coating yield can disrupt prototype schedules and OEM production runs. OPTOStokes mitigates these risks with extensive in-stock inventory, responsive engineering support, and reliable volume delivery. Whether you need a single prototype or a scheduled production run, our team ensures consistent quality and predictable timelines.
