Brand: ThorLabs | Category: Scientific & Laboratory Equipment
Diamond turned off-axis parabolas that focus a collimated beam or collimate a point source without spherical or chromatic aberration. The off-axis geometry moves the focus clear of the beam path, which is useful for spectroscopy and ultrafast work.
| Parameter | Value |

| Average reflectance | greater than 97% from 450 nm to 2 micrometres, greater than 95% from 2 to 20 micrometres |
| Specification | Effective focal lengths from 15 mm (0.59") to 8" (203.2 mm) |
| Reflected wavefront error | less than lambda/4 RMS at 633 nm on most models |
| Surface roughness | less than 100 angstroms RMS |
| Clear aperture | greater than 90% of diameter |
| Mounting adapters | SM-threaded, unthreaded and 8-32 (M4) tapped versions |
