Now You Can Profit from the Advances in Our New Manufacturing Technology

Thin film polarizers based on glass substrates can be used with lasers that have the largest possible power density available. They are used at the Brewster angle and equipped on one side with a dielectric coating. The damage threshold (1064 nm, 10 ns pulse length) reaches into the GW/cm² range and is thus one of the highest available on the market.

New Manufacturing Technology
Said polarizers are manufactured using an IAD (ion assisted deposition) process. This ion assistance helps create compact and thermally stable layers. In addition, the coating process is monitored using a new broadband monitoring system, securing a high efficiency and reaching an accuracy previously not achievable.

What You Gain from the End Product:

• Adjustment-free Application
  In the past, a polarizer had to be adjusted to a certain angle in order to function as efficiently as possible. Now, this component can achieve peak performance when used at any angle between 53° and 59° (see graph; spectral distribution).

• Wavelength Independence
  These new components are available at any wavelength between 450 nm and 1064 nm.
• Improved Specifications
  Because the reflection and transmission values could be significantly improved these new polarizers can also be used for diverging beams or even across a limited wavelength range! For example, at a wavelength of
  532 nm guaranteed values amount to:
  Rs > 99.5?% and Tp > 95?% on average at an angle ranging from 53° – 59°. This corresponds to an extinction ratio of better than 300:1.
