codixx provides following standard products for UV polarizers:
| colorPol® product | Wavelength range [nm] | Transmittance [%] | Contrast k1:k2 | Thickness unlaminated [µm] | Thickness laminated [mm] | Size [mm2] | ||
|---|---|---|---|---|---|---|---|---|
| UV 375 BC5 | 362 - 392 | >40 - 47 | >100,000:1 | 220±50 | 2.0±0.2 | ≤100 x 50 | non laminated / laminated | |
| UV 380 BC4 | 372 - 388 | >52 - 57 | >100,000:1 | 220±50 | 2.0±0.2 | ≤100 x 50 | non laminated / laminated |
The contrast ration in defined to be k1:k2, where k1is the transmittance of a polarized beam passing the filter and k2 is the transmittance of a polarized beam blocked by the filter.
Contrast ratios ≥100,000:1, other thicknesses, shapes or dimensions on request. Reflection losses can be minimized by antireflection coating. AR-coatings are available for different wavelength ranges as V-coating or wide-band version.
