Attention! You can customise this product to your needs.
The main property of Off-axis parabolic mirror is to focus light at an angle with beam propagation axis. This allows to avoid comatic aberration (or coma) that would emerge in case of using spherical mirror at an angle. Off-axis parabolic mirrors come into assistance where usage of transmitting optics is limited, for example due to chromatic aberrations, group velocity dispersion (GVD) or spectral bandwidth. Standard items comprise parabolic mirrors machined by diamond turning technique and coated with protected gold and silver coatings.
