Broad Band Dielectric (BBHR) Mirror is universal optical component with optimized reflection value within designed wide range of wavelengths and angles. What is Broad Band Dielectric (BBHR) Mirror? Main purpose of broad band dielectric (BBHR) mirror is to reflect broad range of wavelengths at designed angle of incidence (AOI). These mirrors have higher (better) reflection, compared to metallic (Gold, Silver, Aluminum) mirrors, but still lower than highly specialized custom laser line or custom double-band mirrors. How broad band dielectric (BBHR) mirrors are made? Borad band dielectric (BBHR) mirror is optical component coated with broad band thin film dielectric optical coatings. Alien Photonics BBHR mirrors are prepared in such way that is very similar to Laser line (HR) mirrors (such as Nd:YAG, Yb:YAG, Ti:Sapphire and double band (DBHR) mirrors (like Nd:YAG, Yb:YAG, Ti:Sapphire, and starts with optical substrate polishing and quality inspection. Optical coating is applied on the substrates after those procedures. BBHR coating design differs from other dielectric mirror coating, because the main goal is to achieve broad desired wavelength range, instead of optimizing for maximal reflection for specific one or two wavelengths. On the other hand, the coating design and procedure itself, follows similar steps. Custom broad band (BBHR) mirrors At Alien Photonics we can customize broad band (BBHR) mirrors according to your needs – small and large size - either diameter, squares, rectangular and custom shapes.
