Mirror Materials
          Mirror material refers to the classification of the material used to make the mirror. The material used influences the reflectivity characteristics of the mirror.
   Your choices are...         
   BK7 Glass       BK7 is boro-crown glass (borosilicate glass). 
   Copper       Copper is typically used in high power applications because of its high thermal conductivity. 
   Fused Silica       Fused silica has a very low coefficient of thermal expansion, and is ideal for use with moderately powered lasers or changing environmental conditions. 
   Nickel       Nickel is considerably more durable than glass substrates, both to thermal and physical damage. 
   Optical Crown Glass       Optical crown glass is typically used in non-imaging applications, including light gathering or conventional beam manipulation tasks. Crown glass is generally used when thermal stability is not a critical factor. 
   Pyrex®       Pyrex® can be used for a wide variety of mirror applications.  This material has good thermal stability. Pyrex is a registered trademark of Corning Incorporated. 
   UV Grade Fused Silica       UV grade fused silica is of higher quality than fused silica. 
   Zerodur®       Zerodur® is a glass-ceramic material that has great thermal stability. It is widely used in applications where the utmost in dimensional stability is needed. Zerodur is a registered trademark of Schott Glass Technologies, Inc. 
   Other Mirror Material       Any other mirror material not listed above.

Mirror Coatings
          Mirror coatings are used to enhance the reflectivity of a mirror.
   Your choices are...         
   Uncoated       No coating on the mirror. 
   Bare Aluminum       Aluminum is an excellent reflector in the upper UV, visible, and near infrared. The surface is soft and must be handled with care. 
   Enhanced Aluminum       Enhanced aluminum has a multilayer film of dielectrics on top to enhance the reflectance in the visible or ultraviolet region. The multilayer film also provides the handling characteristics of the protected aluminum coating. 
   Protected Aluminum       Protected aluminum has a coating as an overcoat to protect the delicate aluminum. This treatment provides an abrasion resistant surface while maintaining the performance of aluminum. 
   Dielectric       Dielectric coatings are multi-layer coatings, which offer excellent performance over a specific wavelength range and are relatively insensitive to small angle changes. Dielectric coatings tend to be more durable than metal coatings. 
   Bare Gold       Gold coatings provide consistently high reflectance in the near-IR to far-IR, and are the most widely used material in these regions. Gold, however, is soft and easily scratched. 
   Protected Gold       Protected gold coatings provide consistently high reflectance in the near-IR to far-IR, and are the most widely used material in these regions. Gold, however, is soft and easily scratched. A protective overcoat provides an abrasive resistant surface, while maintaining the performance of the gold. 
   Rhodium       Rhodium coating has a reflectivity of approximately of 80% throughout the visible spectrum. Rhodium coated nickel is considerably more durable then glass substrates both to thermal and physical damage. 
   Silver       Silver coatings are superior in reflectance to aluminum. However, its strong tendency to oxidize and tarnish means that it must be thoroughly sealed from the atmosphere in order to avoid degradation. 
   Other Mirror Coating       Any other mirror coating not listed above.

Mirror Surface
   Surface Quality:      Surface quality of the filter glass.
   Your choices are...         
   10-5 Scratch / Dig       A dig is a defect on a polished optical surface that is nearly equal in terms of its length and width. A scratch is a defect on a polished optical surface whose length is many times its width. 10 / 5 indicates the average diameter of the digs to be .05 mm and the average length of a scratch is .10 mm. 
   20-10 Scratch / Dig       A dig is a defect on a polished optical surface that is nearly equal in terms of its length and width. A scratch is a defect on a polished optical surface whose length is many times its width. 20 / 10 indicates the average diameter of the digs to be .10 mm and the average length of a scratch is .20 mm. 
   40-20 Scratch / Dig       A dig is a defect on a polished optical surface that is nearly equal in terms of its length and width. A scratch is a defect on a polished optical surface whose length is many times its width. 40 / 20 indicates the average diameter of the digs to be .20 mm and the average length of a scratch is .40 mm. 
   60-40 Scratch / Dig       A dig is a defect on a polished optical surface that is nearly equal in terms of its length and width. A scratch is a defect on a polished optical surface whose length is many times its width. 60 / 40 indicates the average diameter of the digs to be .40 mm and the average length of a scratch is .60 mm. 
   80-50 Scratch / Dig       A dig is a defect on a polished optical surface that is nearly equal in terms of its length and width. A scratch is a defect on a polished optical surface whose length is many times its width. 80 / 50 indicates the average diameter of the digs to be .50 mm and the average length of a scratch is .80 mm. 
   Other       Any other Scratch / Dig surface quality rating.
