Search By Specification


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.
   Frame Thickness:
 
     A pellicle beamsplitter is a thin, stretched plastic membrane cemented to a rigid supporting ring. Frame thickness refers to the thickness 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.
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.
 
   InconelĀ®
 
     InconelĀ® 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.
Pellicle Beamsplitter Surface




   Surface Quality:      Surface quality of the pellicle 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 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).
 
   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).
 
   lambda/2
 
     The biggest variation in surface height for the beamsplitter is no more then lambda/2 (lambda=633nm).
 
   Other
