Coating Type | Properties and Applications | |
Antireflection |
Single Layer MgF2 | Applied to materials with refractive indices from 1.45 to 2.4. The most popular antireflective coating for visible wavelengths. It is insensitive to change in incidence angles. |
Multilayer "V" | Used to provide low reflectance within a narrow durable wavelength band for most laser applications. Minimum reflection can be less than 0.1%. | |
Broadband Mutilayer | These coating have excellent performance over a broad special broadband. Coating performance is sensitive to angle of incidence. | |
Dual Wavelength Band | Offer very low reflectance at two widely spaced wave lengths, such as Nd: YAG Laser (1064) and its second harmonic (532). | |
Partial Reflection |
Narrow Band | Provide 50% reflection and transmission at an angle of 45° incidence for a single wavelength. Perfect for beamsplitter applications. Transmission/reflection (T/R) ratio of 20/80. Additional T/R ratios for beamsplitter are available upon request. |
Broadband | Provide 50% reflection and transmission over a wide bandwidth. CASIX also provides coating with different R/T ratios and specific angles of incidence. | |
Beamsplitter | Laser Line Polarizing Beamsplitters | High reflection for s-polarized and antireflection for p-polarized for laser applications. |
Broadband Polarizing Beamsplitters | Wide wavelength bandwidths provide high reflection to s-polarized and antireflection to p-polarized. | |
Dichroic Beamsplitter Mirrors | These coatings separate the laser fun damental and the pump wavelength or the fundamental and the second ha rmonic. They are specifically applied to laser mirrors. | |
DPSSLasers | Diode Pumped LaserOptics Coating (DPO) | These coatings are designed for a diode pumped laser. They can be deposited on a variety of substrates and have a high damage threshold. |
High Reflection | Dielectric High Reflective Coatings | Provide high reflectance over a broad bandwidth and are ideal for tunable lasers or white light applications. |
Metallic High Reflective Coatings | Metallic coating have low peak reflectance, mechanical durability and a high damage threshold, but they have an extremely broad bandwidth and low cost. They are insensitive to angle of incident light and polarization. | |
