CM1-P01 In Stock

The CM1-P01 by ThorLabs is an exceptional cage cube-mounted turning mirror that provides increased flexibility when constructing optical devices from compatible cage systems and lens tube products. The CM1-P01 features a protected silver metallic coating and has the part number engraved on the housing, making it easy to identify.

One of the most significant benefits of the CM1-P01 is its pre-alignment, which ensures that the reflected beam exits to within ±20 arcmin of 90º, significantly reducing the time required to align the mirror in a setup. For even higher accuracy or greater alignment flexibility, 90 degree turning mirror kinematic mounts can be used. The reflective coating of protected silver enhances the performance of the mirror. The CM1-P01 is also highly versatile, with the ability to be post-mounted using a bottom-mounted M6 x 0.5 tap. It is compatible with 8­32 and M4 adapters, ensuring compatibility with both imperial and metric post systems. The entrance and exit ports feature SM1 threading, which is compatible with SM1 lens tubes, and four 4­40 taps that accept Ø6 mm cage rods. The CM1-P01 can also be connected to other cage cubes using compatible cage rods and ERSCA adapters.

Moreover, the CM1-P01 includes a Laser Induced Damage Threshold (LIDT), which is an important consideration when determining the suitability of an optic for a particular application. The LIDT varies depending on the type of laser used. For example, CW lasers tend to cause thermal damage to the material due to melting of the surface, while pulsed lasers can strip electrons from the lattice structure and lead to thermal damage before any visual changes occur. To use the specified CW damage threshold, it is necessary to know the laser's wavelength, the linear power density of the beam, the beam diameter, and the approximate intensity profile of the beam. It's critical to keep surfaces clean and free of debris when examining the LIDT to prevent dust and other particles on the optic's surface from causing damage at lower thresholds.
