◦A data of transmitted wavefront measurement or reflected wavefront by the interferometer is provided.
◦We offer a selection of substrates made from various low-expansion material suitable to the required accuracy and environment of your use.
◦Thin film coatings are also available on the master optics. However, depending on the type of coating it we may not be able to guarantee the surface flatness.

| Guide | ▶Optical flats (HMPQP / HMPZP) that has been standardized by the reflecting surface flatness are available. WEB Reference Catalog Code/W3145 ▶Optical flats (OFPXP) with surface flatness of λ/10 and less φ150mm are available. WEB Reference Catalog Code/W3151 |
| Attention | ▶Surface flatness may not be guaranteed if coating is applied to master optics. ▶Due to the difficulty in procurement of the materials and processing conditions, lead-time may be longer, please check with our Sales Division for accurate delivery. ▶If the holder is fixed to the master optics, by tightening screws too strongly, or the use of curable adhesives the surface flatness may be reduce on the master optics. |
