Designed to focus light into a single line rather than a point. Ideal for laser scanning and transforming circular beams into elliptical shapes.
Plano-concave mirrors are designed to reflect and focus (or converge) incident light beams. By applying various reflective coatings to the concave surface, these mirrors can be optimized for the ultraviolet (UV), visible, or infrared (IR) spectral ranges. We offer both uncoated substrates and protected aluminum-coated mirrors, with fully customized solutions available upon request to meet your specific application requirements.

Hengpu also offers high-reflectivity coatings, including Aluminum, Gold, Silver, and UV-Enhanced Aluminum.
Protected Gold Coatings: Enhances reflectivity across the visible and infrared (IR) spectrums.
Protected Silver Coatings: Provides higher reflectivity than aluminum coatings in the visible and near-infrared (NIR) spectrums.
Protected Aluminum Coatings: Boosts reflectivity within the visible light range.
UV-Enhanced Aluminum Coatings: Delivers enhanced reflectivity in both the ultraviolet (UV) and visible spectrums.
