TFM-40C06-1064 40 mm Diameter N-BK7 Laser Line Mirror; t=6mm Dielectric Multi-Layer 1064nm

The TFM-40C06-1064 is a high-quality laser line mirror from OptoSigma, designed with a 40 mm diameter and a thickness of 6mm. This mirror is specifically engineered for use with a 1064nm wavelength, making it an ideal choice for a variety of applications that require precise laser control.

The mirror is made from N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is particularly prized for its low coefficient of thermal expansion, high homogeneity, and excellent transmission in the visible and near-infrared regions of the spectrum. The use of N-BK7 ensures that the mirror provides reliable and consistent performance, even in challenging environmental conditions.

The mirror's coating is a dielectric multi-layer, designed to optimize reflectivity at the 1064nm wavelength. This coating is applied to the front surface of the mirror, and it is characterized by its high damage threshold and excellent environmental stability. The AOI (Angle of Incidence) for this coating is 45 degrees, which is a common angle for many laser applications.

The mirror's shape is thin lens, which means it has been specifically designed to minimize optical aberrations and distortions. This shape, combined with the mirror's high-quality materials and coatings, ensures that the mirror provides precise and accurate laser control.
