Excimer Laser Optics

 

 

Acton Optics include the highest quality optical components for all excimer laser wavelengths, including:

We are continuously improving our thin film designs and coating processes to meet the rigorous applications these and other markets:

  • Medical
  • Semiconductor
  • Industrial
  • Research

Excimer Laser Mirrors

Our high-power excimer laser mirrors are multi-layer dielectric coated mirrors designed for use with high energy excimer lasers. These coatings have yielded superior high damage thresholds. We maintain a stock supply of these beam-turning and normal incidence mirrors for fast delivery to your facility. Mirrors and coatings on Acton mirror blanks or customer supplied material can be produced and supplied in volume, keeping the price very competitive.

Acton Optics multi-layer dielectric coatings are ideal for beamsplitting applications, laser cavity output couplers, and beam attenuators. These coatings are manufactured with extremely low absorption characteristics. They are calibrated for reflectance and transmittance at the laser wavelength and angle of incidence specified to insure excellent performance in high power laser applications.

Beamplitter coatings can be specifically designed with transmission values between 10 +/-2% to 90 +/-5%. Standard beamsplitters are designed for random polarization, but can be optimized for horizontal "P" polarization or vertical "S" polarization if required. Beamsplitters are available with or without antireflection coatings.

Excimer Laser Antireflection Coatings

UV antireflection coatings are durable electron-beam deposited dielectrics designed to minimize reflections that normally occur with uncoated surfaces. These low-absorption coatings are ideal for increasing the transmittance properties of lenses and for reducing second-surface reflections of beamsplitters. They offer high resistance to laser damage, making them suitable for high-energy laser usage. Coatings can be applied to customer-supplied material or provided on our substrates and lenses. (Reflectance of uncoated fused silica is 4.8% per surface at 193 nm and 4.1% per surface at 248 nm).

Listed below are standard excimer laser antireflection coatings with specifications and calibration curves for your reference.
