Help with Pellicle Beamsplitters specifications:

Pellicle Beamsplitter Geometry
   Frame Diameter:       A pellicle beamsplitter is a thin, stretched plastic membrane cemented to a rigid supporting ring. Frame diameter refers to the diameter of the supporting ring. 
   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.
   Clear Aperture:       A pellicle beamsplitter is a thin, stretched plastic membrane cemented to a rigid supporting ring. Clear aperture refers to the diameter of the effective area of the pellicle. 
   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.

Pellicle Beamsplitter Performance
   Temperature Range:       The temperature range in which the beamsplitter is designed to work. 
   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.
   Wavelength Range:       The wavelength range in which the beamsplitter is designed to work. 
   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.
   Transmission:       The percent transmitted light of the incident light. 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.

Coatings
           
   Your choices are...         
   None       The beamsplitter has no coating. 
   Dielectric       Dielectric coatings are designed for a specific wavelength. 
   Inconel®       Inconel® coating contains nickel, chromium, cobalt, and iron. A thin Inconel film balances the transmission of each element, resulting in a wavelength neutral coating.  Inconel is a registered trademark of the INCO family of companies. 
   Search Logic:      Products with the selected attribute will be returned as matches. Leaving or selecting "No Preference" will not limit the search criteria for this question; products with all attribute options will be returned as matches.

   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 pellicle beamsplitter, given in terms of lambda(lambda=633nm).
   Your choices are...         
   lambda/4       The biggest variation in surface height for the beamsplitter is no more then lambda/4 (lambda=633nm).
