The ThorLabs BB05-E02 is a premium dielectric mirror designed to deliver high reflectance across a broad spectrum of 400 to 750 nanometers. The BB05-E02’s circular design has a Ø1/2" diameter and is constructed with a substrate made of fused silica for exceptional durability.
The BB05-E02 is specifically designed to be used with both nanosecond and continuous wave lasers, providing a minimum average reflectance of 99% for S-polarization and P-polarization for the angle formed at the point of incident in the 0 degree to 45 degree angle range. The back of the mirror is conveniently engraved with its unique part number for easy identification. It is important to note that the BB05-E02's spectral range is smaller than the actual spectral region over which the mirror is effective, which is a result of run-to-run coating variations.
