Transmission polarizers have polarizing coatings on both sides of the polarizer. They can be optimized for highest transmission of p polarization Tp>94% or best contrast of polarizations Tp:Ts>20:1.
Reflection Polarizers have polarizing coating on the input face while the output face is AR coated for both s and p polarizations. They can be optimized for highest reflection of s polarization Rs>98% or best contrast of polarizations Rs:Rp>60:1. Moreover, the AR coated side of a polarizer can have wedge to minimize ghosting.
Standard thin film polarizers are designed for optimum performance in the 750 - 850 nm or 980 - 1090 nm range. Design of custom wavelength range is also available.
|Efficiently separates the s and p polarization components|
|Many Broadband (ultrafast) Thin Film polarizers are available from STOCK with fast delivery|
|Available in dimensions up to 160x50 mm|
|Optimised for popular laser wavelengths|
Polymer film First Contact™ is a unique product designed for laser optics protection, preservation and cleaning. For all sorts of optical items it serves as a protection layer from damages during shipping, long term storage, environment changes, etc. and removes all dust and other contamination after the film is removed from the optical surface. It is absolutely safe for almost all types of optics and optical coatings.*
- Protects against scratching, abrasion, dirt, and water damage. Also protects against corrosion caused by water vapor, oxygen, and sulfur.
- Cleans the surface, removes particulates and organic contaminants.
- Leaves no residue.
- Leaves no hazardous waste.
- Safe to store for up to 4 years (period may be extended depending on storing conditions).
- Comes off in one piece.
- Does not lift metal from metal films.
- Safe with temperatures up to 200° C.
- Environmentally friendly
* Protective polymer cannot be used with optical components sensitive to acetate.
Price – 3 EUR per item (price includes coating service and polymer)
If you want to order protective coating please select "Optics Protection" in the catalog list.
Holding the sticker slowly peel the film starting from the edge. If necessary place the optic in its corresponding mount prior to removing the film.
