Beamsplitter Geometry
   Beamsplitter Shape:      Beamsplitters can either come round, square, or rectangular.
   Your choices are...         
   Circular       The beamsplitter is circular shaped. 
   Square       The beamsplitter is square shaped. 
   Rectangular       The beamsplitter is rectangular shaped. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Diameter, Square Side, or Rectangular Length:       If the beamsplitter is circular, the diameter. If the beamsplitter is square, the length of a side. If the beamsplitter is rectangular, the length of its longest side. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Rectangular Width:       If the beamsplitter is rectangular, the length of its shorter side. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Thickness:       The thickness of the beamsplitter. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Beamsplitter Performance
   Wavelength Range:       The wavelength range the beamsplitter is designed to work in . 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
   Minimum Beam Diameter       The minimum beam diameter for 50/50 reflectance / transmittance. 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.

Window Surface
   Surface Quality:      Surface quality of the beamsplitter.
   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. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Surface Flatness:      The surface flatness of the beamsplitter, given in terms of lambda(lambda=633nm).
   Your choices are...         
   lambda/2       The biggest variation in surface height for the beamsplitter is no more then lambda/2 (lambda=633nm). 
   lambda/4       The biggest variation in surface height for the beamsplitter is no more then lambda/4 (lambda=633nm). 
   lambda/5       The biggest variation in surface height for the beamsplitter is no more then lambda/5 (lambda=633nm). 
   lambda/8       The biggest variation in surface height for the beamsplitter is no more then lambda/8 (lambda=633nm). 
   lambda/10       The biggest variation in surface height for the beamsplitter is no more then lambda/10 (lambda=633nm). 
   lambda/20       The biggest variation in surface height for the beamsplitter is no more then lambda/20 (lambda=633nm). 
   Other       Any other surface flatness in terms of lambda(lambda=633nm). 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
