Polarizer Construction
Back to Top
|
| ||
| Polarizer Construction: | Polarizing beamsplitter cubes consist of two halves, which must be fixed in relation to one another by either mounting or cement. | ||
| Your choices are... | |||
| Cement | Two halves cemented together. | ||
| Mounted | Two halves mounted together. | ||
| 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. | ||
| |||
| Cube Side Length: | The length of one side of the cube. From that length the area of the cube can be determined. | ||
| 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. | ||
| |||
Polarizer Performance

|
|
| ||
| Transmission: | Transmission is the ratio of total straight through output to total unpolarized input. | ||
| Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||
| |||
| Wavelength Range: | The wavelength range the polarizer 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. | ||
| |||
| Extinction Ratio: | The ratio of the power of a plane-polarized beam that is transmitted through a polarizer placed in its path with its polarizing axis parallel to the beam's plane, as compared with the transmitted power when the polarizer's axis is perpendicular to the beam's plane. | ||
| Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||
| |||
| Beam Deviation: | The deviation of the polarized beam from normal. | ||
| Search Logic: | All matching products will have a value less than or equal to the specified value. | ||
| |||
Polarizer Features

|
|
| ||
| Coating: | Some polarizers are coated to increase transmission of light at the polarizer-air interface. | ||
| Your choices are... | |||
| None | Polarizing beamsplitter cube has no coating. | ||
| Antireflective | Polarizing beamsplitter cube has an antireflective coating. | ||
| 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. | ||

Polarizer Material
Back to Top
|
|
| ||
| Polarizer Material | Since polarizing cube beamsplitters use reflection to polarize light, materials that comprise these cubes lack the bifringency provided by other types of polarizers. The materials tend to be more bandpass oriented. | ||
| Your choices are... | |||
| BK7 Glass | BK7 Glass is boro-crown glass (borosilicate glass). BK7 has a wavelength range of 330-2100 nm. | ||
| SF2 Glass | SF2 Glass is dense flint (alkaline silicate glasses with 47% wt. PbO). | ||
| UV grade fused Silica | UV grade fused silica offer improved transmission in the ultraviolet region compared to crown glass. The wavelength range is 200-2500 nm. | ||
| Other Material | Any other polarizing beamsplitter cube material. | ||
| 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. | ||
