Thorlabs fused silica broadband dielectric film mirror provides excellent reflectivity in four different spectral ranges. Please note that due to different coating batches, the specified spectral range for each coating layer is smaller than the actual effective spectral range of the reflector.Reflectance curveThe label provides the performance characteristics of typical mirrors near the edge of the effective spectral range.
Ø 1/2 inch, Ø 1 inch, and Ø 2 inch circular reflectors are also sold in packs of 10, with lower individual prices.
As shown in Figure 1.1, the back of each reflector is engraved with the corresponding product model, except for Ø 7.0 mm reflectors.
Figure 1.2 shows the reflectance curves of each broadband reflective film in the BB series as a function of non polarized incident light wavelength, with incident angles of 6 ° or 8 °. The reason for choosing this incident angle is that the measurement at 0 ° incidence is limited; But this curve shows the reflectance at an incident angle close to 0 °. For details on reflectivity with different polarization states, please refer toReflectance curvelabel.
If your application requires a small portion of the light beam to pass through a mirror, please choose ourBack polished reflectorAdditionally, if your application requires mirrors to span across two different dielectric film ranges, you may consider using a coating with金属膜The reflector; If you need to order mirrors in bulk, please contact our technical team
