Products Description

Protected Aluminum Mirror | 420-680nm, Ravg > 90%

The OPTOStokes Protected Aluminum Mirror provides high, flat reflectivity across the entire visible wavelength range from 420 to 680 nm. Designed with a durable dielectric overcoat on a vacuum-deposited aluminum film, this broadband mirror delivers exceptional environmental resistance, preventing oxidation while maintaining an average reflectance greater than 90%. It is a versatile optical component for broad-spectrum light routing, alignment, and imaging systems.

Primary Applications

Due to its flat spectral response and cost-effective Broadband reflection, these specialized optical mirrors are widely integrated into:

  • Spectrophotometers & Spectrometers: Directing broad-spectrum visible illumination through optical paths without introducing color distortion.

  • Multispectral Imaging Systems: Folding optical paths and guiding light in compact industrial vision equipment.

  • Optical R&D Setup: Serving as reliable, general-purpose beam-steering elements for laboratory laser and broadband light sources.

Customization & Assembly Options

OPTOStokes stocks an extensive inventory of standard round and square planar reflectors for quick-turn dispatch. To support tailored OEM integrations, we provide custom processing including specialized geometries (elliptical, custom CNC cutouts), custom thickness profiling, and threaded mounting ring housing options. Our precision protected aluminum mirrors undergo strict spectrophotometric testing to meet stringent wavefront and scratch-dig standards.
